Obj. 2: Further, we share bodies with the brutes. If therefore Christ was the Head of men as to their bodies, it would follow that He was the Head of brute animals; and this is not fitting.

Obj. 3: Further, Christ took His body from other men, as is clear from Matt. 1 and Luke 3. But the head is the first of the members, as was said above (A. 1, ad 3). Therefore Christ is not the Head of the Church as regards bodies.

On the contrary, It is written (Phil. 3:21): "Who will reform the body of our lowness, made like to the body of His glory."

I answer that, The human body has a natural relation to the rational soul, which is its proper form and motor. Inasmuch as the soul is its form, it receives from the soul life and the other properties which belong specifically to man; but inasmuch as the soul is its motor, the body serves the soul instrumentally. Therefore we must hold that the manhood of Christ had the power of influence, inasmuch as it is united to the Word of God, to Whom His body is united through the soul, as stated above (Q. 6, A. 1). Hence the whole manhood of Christ, i.e. according to soul and body, influences all, both in soul and body; but principally the soul, and secondarily the body: First, inasmuch as the "members of the body are presented as instruments of justice" in the soul that lives through Christ, as the Apostle says (Rom. 6:13): secondly, inasmuch as the life of glory flows from the soul on to the body, according to Rom. 8:11: "He that raised up Jesus from the dead shall quicken also your mortal bodies, because of His Spirit that dwelleth in you."

Reply Obj. 1: The spiritual sense of grace does not reach to the body first and principally, but secondarily and instrumentally, as was said above.

Reply Obj. 2: The body of an animal has no relation to a rational soul, as the human body has. Hence there is no parity.

Reply Obj. 3: Although Christ drew the matter of His body from other men, yet all draw from Him the immortal life of their body, according to 1 Cor. 15:22: "And as in Adam all die, so also in Christ all shall be made alive." _____

THIRD ARTICLE [III, Q. 8, Art. 3]

Whether Christ Is the Head of All Men?

Objection 1: It would seem that Christ is not the Head of all men. For the head has no relation except to the members of its body. Now the unbaptized are nowise members of the Church which is the body of Christ, as it is written (Eph. 1:23). Therefore Christ is not the Head of all men.

Obj. 2: Further, the Apostle writes to the Ephesians (5:25, 27): "Christ delivered Himself up for" the Church "that He might present it to Himself a glorious Church, not having spot or wrinkle or any such thing." But there are many of the faithful in whom is found the spot or the wrinkle of sin. Therefore Christ is not the Head of all the faithful.

Obj. 3: Further, the sacraments of the Old Law are compared to Christ as the shadow to the body, as is written (Col. 2:17). But the fathers of the Old Testament in their day served unto these sacraments, according to Heb. 8:5: "Who serve unto the example and shadow of heavenly things." Hence they did not pertain to Christ's body, and therefore Christ is not the Head of all men.

On the contrary, It is written (1 Tim. 4:10): "Who is the Saviour of all men, especially of the faithful," and (1 John 2:2): "He is the propitiation for our sins, and not for ours only, but also for those of the whole world." Now to save men and to be a propitiation for their sins belongs to Christ as Head. Therefore Christ is the Head of all men.

I answer that, This is the difference between the natural body of man and the Church's mystical body, that the members of the natural body are all together, and the members of the mystical are not all together—neither as regards their natural being, since the body of the Church is made up of the men who have been from the beginning of the world until its end—nor as regards their supernatural being, since, of those who are at any one time, some there are who are without grace, yet will afterwards obtain it, and some have it already. We must therefore consider the members of the mystical body not only as they are in act, but as they are in potentiality. Nevertheless, some are in potentiality who will never be reduced to act, and some are reduced at some time to act; and this according to the triple class, of which the first is by faith, the second by the charity of this life, the third by the fruition of the life to come. Hence we must say that if we take the whole time of the world in general, Christ is the Head of all men, but diversely. For, first and principally, He is the Head of such as are united to Him by glory; secondly, of those who are actually united to Him by charity; thirdly, of those who are actually united to Him by faith; fourthly, of those who are united to Him merely in potentiality, which is not yet reduced to act, yet will be reduced to act according to Divine predestination; fifthly, of those who are united to Him in potentiality, which will never be reduced to act; such are those men existing in the world, who are not predestined, who, however, on their departure from this world, wholly cease to be members of Christ, as being no longer in potentiality to be united to Christ.

Reply Obj. 1: Those who are unbaptized, though not actually in the Church, are in the Church potentially. And this potentiality is rooted in two things—first and principally, in the power of Christ, which is sufficient for the salvation of the whole human race; secondly, in free-will.

Reply Obj. 2: To be "a glorious Church not having spot or wrinkle" is the ultimate end to which we are brought by the Passion of Christ. Hence this will be in heaven, and not on earth, in which "if we say we have no sin, we deceive ourselves," as is written (1 John 1:8). Nevertheless, there are some, viz. mortal, sins from which they are free who are members of Christ by the actual union of charity; but such as are tainted with these sins are not members of Christ actually, but potentially; except, perhaps, imperfectly, by formless faith, which unites to God, relatively but not simply, viz. so that man partake of the life of grace. For, as is written (James 2:20): "Faith without works is dead." Yet such as these receive from Christ a certain vital act, i.e. to believe, as if a lifeless limb were moved by a man to some extent.

Reply Obj. 3: The holy Fathers made use of the legal sacraments, not as realities, but as images and shadows of what was to come. Now it is the same motion to an image as image, and to the reality, as is clear from the Philosopher (De Memor. et Remin. ii). Hence the ancient Fathers, by observing the legal sacraments, were borne to Christ by the same faith and love whereby we also are borne to Him, and hence the ancient Fathers belong to the same Church as we. _____

FOURTH ARTICLE [III, Q. 8, Art. 4]

Whether Christ Is the Head of the Angels?

Objection 1: It would seem that Christ as man is not the head of the angels. For the head and members are of one nature. But Christ as man is not of the same nature with the angels, but only with men, since, as is written (Heb. 2:16): "For nowhere doth He take hold of the angels, but of the seed of Abraham He taketh hold." Therefore Christ as man is not the head of the angels.

Obj. 2: Further, Christ is the head of such as belong to the Church, which is His Body, as is written (Eph. 1:23). But the angels do not belong to the Church. For the Church is the congregation of the faithful: and in the angels there is no faith, for they do not "walk by faith" but "by sight," otherwise they would be "absent from the Lord," as the Apostle argues (2 Cor. 5:6, 7). Therefore Christ as man is not head of the angels.

Obj. 3: Further, Augustine says (Tract. xix; xxiii in Joan.), that as "the Word" which "was in the beginning with the Father" quickens souls, so the "Word made flesh" quickens bodies, which angels lack. But the Word made flesh is Christ as man. Therefore Christ as man does not give life to angels, and hence as man He is not the head of the angels.

On the contrary, The Apostle says (Col. 2:10), "Who is the head of all Principality and Power," and the same reason holds good with the other orders of angels. Therefore Christ is the Head of the angels.

I answer that, As was said above (A. 1, ad 2), where there is one body we must allow that there is one head. Now a multitude ordained to one end, with distinct acts and duties, may be metaphorically called one body. But it is manifest that both men and angels are ordained to one end, which is the glory of the Divine fruition. Hence the mystical body of the Church consists not only of men but of angels. Now of all this multitude Christ is the Head, since He is nearer God, and shares His gifts more fully, not only than man, but even than angels; and of His influence not only men but even angels partake, since it is written (Eph. 1:20-22): that God the Father set "Him," namely Christ, "on His right hand in the heavenly places, above all Principality and Power and Virtue and Dominion and every name that is named not only in this world, but also in that which is to come. And He hath subjected all things under His feet." Therefore Christ is not only the Head of men, but of angels. Hence we read (Matt. 4:11) that "angels came and ministered to Him."

Reply Obj. 1: Christ's influence over men is chiefly with regard to their souls; wherein men agree with angels in generic nature, though not in specific nature. By reason of this agreement Christ can be said to be the Head of the angels, although the agreement falls short as regards the body.

Reply Obj. 2: The Church, on earth, is the congregation of the faithful; but, in heaven, it is the congregation of comprehensors. Now Christ was not merely a wayfarer, but a comprehensor. And therefore He is the Head not merely of the faithful, but of comprehensors, as having grace and glory most fully.

Reply Obj. 3: Augustine here uses the similitude of cause and effect, i.e. inasmuch as corporeal things act on bodies, and spiritual things on spiritual things. Nevertheless, the humanity of Christ, by virtue of the spiritual nature, i.e. the Divine, can cause something not only in the spirits of men, but also in the spirits of angels, on account of its most close conjunction with God, i.e. by personal union. _____

FIFTH ARTICLE [III, Q. 8, Art. 5]

Whether the Grace of Christ, As Head of the Church, Is the Same As His Habitual Grace, Inasmuch As He Is Man?

Objection 1: It would seem that the grace whereby Christ is Head of the Church and the individual grace of the Man are not the same. For the Apostle says (Rom. 5:15): "If by the offense of one many died, much more the grace of God and the gift, by the grace of one man, Jesus Christ, hath abounded unto many." But the actual sin of Adam is distinct from original sin which he transmitted to his posterity. Hence the personal grace which is proper to Christ is distinct from His grace, inasmuch as He is the Head of the Church, which flows to others from Him.

Obj. 2: Further, habits are distinguished by acts. But the personal grace of Christ is ordained to one act, viz. the sanctification of His soul; and the capital grace is ordained to another, viz. to sanctifying others. Therefore the personal grace of Christ is distinct from His grace as He is the Head of the Church.

Obj. 3: Further, as was said above (Q. 6, A. 6), in Christ we distinguish a threefold grace, viz. the grace of union, capital grace, and the individual grace of the Man. Now the individual grace of Christ is distinct from the grace of union. Therefore it is also distinct from the capital grace.

On the contrary, It is written (John 1:16): "Of His fulness we all have received." Now He is our Head, inasmuch as we receive from Him. Therefore He is our Head, inasmuch as He has the fulness of grace. Now He had the fulness of grace, inasmuch as personal grace was in Him in its perfection, as was said above (Q. 7, A. 9). Hence His capital and personal grace are not distinct.

I answer that, Since everything acts inasmuch as it is a being in act, it must be the same act whereby it is in act and whereby it acts, as it is the same heat whereby fire is hot and whereby it heats. Yet not every act whereby anything is in act suffices for its being the principle of acting upon others. For since the agent is nobler than the patient, as Augustine says (Gen. ad lit. xii, 16) and the Philosopher (De Anima iii, 19), the agent must act on others by reason of a certain pre-eminence. Now it was said above (A. 1; Q. 7, A. 9) grace was received by the soul of Christ in the highest way; and therefore from this pre-eminence of grace which He received, it is from Him that this grace is bestowed on others—and this belongs to the nature of head. Hence the personal grace, whereby the soul of Christ is justified, is essentially the same as His grace, as He is the Head of the Church, and justifies others; but there is a distinction of reason between them.

Reply Obj. 1: Original sin in Adam, which is a sin of the nature, is derived from his actual sin, which is a personal sin, because in him the person corrupted the nature; and by means of this corruption the sin of the first man is transmitted to posterity, inasmuch as the corrupt nature corrupts the person. Now grace is not vouchsafed us by means of human nature, but solely by the personal action of Christ Himself. Hence we must not distinguish a twofold grace in Christ, one corresponding to the nature, the other to the person as in Adam we distinguish the sin of the nature and of the person.

Reply Obj. 2: Different acts, one of which is the reason and the cause of the other, do not diversify a habit. Now the act of the personal grace which is formally to sanctify its subject, is the reason of the justification of others, which pertains to capital grace. Hence it is that the essence of the habit is not diversified by this difference.

Reply Obj. 3: Personal and capital grace are ordained to an act; but the grace of union is not ordained to an act, but to the personal being. Hence the personal and the capital grace agree in the essence of the habit; but the grace of union does not, although the personal grace can be called in a manner the grace of union, inasmuch as it brings about a fitness for the union; and thus the grace of union, the capital, and the personal grace are one in essence, though there is a distinction of reason between them. _____

SIXTH ARTICLE [III, Q. 8, Art. 6]

Whether It Is Proper to Christ to Be Head of the Church?

Objection 1: It seems that it is not proper to Christ to be Head of the Church. For it is written (1 Kings 15:17): "When thou wast a little one in thy own eyes, wast thou not made the head of the tribes of Israel?" Now there is but one Church in the New and the Old Testament. Therefore it seems that with equal reason any other man than Christ might be head of the Church.

Obj. 2: Further, Christ is called Head of the Church from His bestowing grace on the Church's members. But it belongs to others also to grant grace to others, according to Eph. 4:29: "Let no evil speech proceed from your mouth; but that which is good to the edification of faith, that it may administer grace to the hearers." Therefore it seems to belong also to others than Christ to be head of the Church.

Obj. 3: Further, Christ by His ruling over the Church is not only called "Head," but also "Shepherd" and "Foundation." Now Christ did not retain for Himself alone the name of Shepherd, according to 1 Pet. 5:4, "And when the prince of pastors shall appear, you shall receive a never-fading crown of glory"; nor the name of Foundation, according to Apoc. 21:14: "And the wall of the city had twelve foundations." Therefore it seems that He did not retain the name of Head for Himself alone.

On the contrary, It is written (Col. 2:19): "The head" of the Church is that "from which the whole body, by joints and bands being supplied with nourishment and compacted groweth unto the increase of God." But this belongs only to Christ. Therefore Christ alone is Head of the Church.

I answer that, The head influences the other members in two ways. First, by a certain intrinsic influence, inasmuch as motive and sensitive force flow from the head to the other members; secondly, by a certain exterior guidance, inasmuch as by sight and the senses, which are rooted in the head, man is guided in his exterior acts. Now the interior influx of grace is from no one save Christ, Whose manhood, through its union with the Godhead, has the power of justifying; but the influence over the members of the Church, as regards their exterior guidance, can belong to others; and in this way others may be called heads of the Church, according to Amos 6:1, "Ye great men, heads of the people"; differently, however, from Christ. First, inasmuch as Christ is the Head of all who pertain to the Church in every place and time and state; but all other men are called heads with reference to certain special places, as bishops of their Churches. Or with reference to a determined time as the Pope is the head of the whole Church, viz. during the time of his Pontificate, and with reference to a determined state, inasmuch as they are in the state of wayfarers. Secondly, because Christ is the Head of the Church by His own power and authority; while others are called heads, as taking Christ's place, according to 2 Cor. 2:10, "For what I have pardoned, if I have pardoned anything, for your sakes I have done it in the person of Christ," and 2 Cor. 5:20, "For Christ therefore we are ambassadors, God, as it were, exhorting by us."

Reply Obj. 1: The word "head" is employed in that passage in regard to exterior government; as a king is said to be the head of his kingdom.

Reply Obj. 2: Man does not distribute grace by interior influx, but by exteriorly persuading to the effects of grace.

Reply Obj. 3: As Augustine says (Tract. xlvi in Joan.): "If the rulers of the Church are Shepherds, how is there one Shepherd, except that all these are members of one Shepherd?" So likewise others may be called foundations and heads, inasmuch as they are members of the one Head and Foundation. Nevertheless, as Augustine says (Tract. xlvii), "He gave to His members to be shepherds; yet none of us calleth himself the Door. He kept this for Himself alone." And this because by door is implied the principal authority, inasmuch as it is by the door that all enter the house; and it is Christ alone by "Whom also we have access . . . into this grace, wherein we stand" (Rom. 5:2); but by the other names above-mentioned there may be implied not merely the principal but also the secondary authority. _____

SEVENTH ARTICLE [III, Q. 8, Art. 7]

Whether the Devil Is the Head of All the Wicked?

Objection 1: It would seem that the devil is not the head of the wicked. For it belongs to the head to diffuse sense and movement into the members, as a gloss says, on Eph. 1:22, "And made Him head," etc. But the devil has no power of spreading the evil of sin, which proceeds from the will of the sinner. Therefore the devil cannot be called the head of the wicked.

Obj. 2: Further, by every sin a man is made evil. But not every sin is from the devil; and this is plain as regards the demons, who did not sin through the persuasion of another; so likewise not every sin of man proceeds from the devil, for it is said (De Eccles. Dogm. lxxxii): "Not all our wicked thoughts are always raised up by the suggestion of the devil; but sometimes they spring from the movement of our will." Therefore the devil is not the head of all the wicked.

Obj. 3: Further, one head is placed on one body. But the whole multitude of the wicked do not seem to have anything in which they are united, for evil is contrary to evil and springs from divers defects, as Dionysius says (Div. Nom. iv). Therefore the devil cannot be called the head of all the wicked.

On the contrary, A gloss [*St. Gregory, Moral. xiv] on Job 18:17, "Let the memory of him perish from the earth," says: "This is said of every evil one, yet so as to be referred to the head," i.e. the devil.

I answer that, As was said above (A. 6), the head not only influences the members interiorly, but also governs them exteriorly, directing their actions to an end. Hence it may be said that anyone is the head of a multitude, either as regards both, i.e. by interior influence and exterior governance, and thus Christ is the Head of the Church, as was stated (A. 6); or as regards exterior governance, and thus every prince or prelate is head of the multitude subject to him. And in this way the devil is head of all the wicked. For, as is written (Job 41:25): "He is king over all the children of pride." Now it belongs to a governor to lead those whom he governs to their end. But the end of the devil is the aversion of the rational creature from God; hence from the beginning he has endeavored to lead man from obeying the Divine precept. But aversion from God has the nature of an end, inasmuch as it is sought for under the appearance of liberty, according to Jer. 2:20: "Of old time thou hast broken my yoke, thou hast burst my bands, and thou saidst, 'I will not serve.'" Hence, inasmuch as some are brought to this end by sinning, they fall under the rule and government of the devil, and therefore he is called their head.

Reply Obj. 1: Although the devil does not influence the rational mind interiorly, yet he beguiles it to evil by persuasion.

Reply Obj. 2: A governor does not always suggest to his subjects to obey his will; but proposes to all the sign of his will, in consequence of which some are incited by inducement, and some of their own free-will, as is plain in the leader of an army, whose standard all the soldiers follow, though no one persuades them. Therefore in the same way, the first sin of the devil, who "sinneth from the beginning" (1 John 3:8), is held out to all to be followed, and some imitate at his suggestion, and some of their own will without any suggestion. And hence the devil is the head of all the wicked, inasmuch as they imitate Him, according to Wis. 2:24, 25: "By the envy of the devil, death came into the world. And they follow him that are of his side."

Reply Obj. 3: All sins agree in aversion from God, although they differ by conversion to different changeable goods. _____

EIGHTH ARTICLE [III, Q. 8, Art. 8]

Whether Antichrist May Be Called the Head of All the Wicked?

Objection 1: It would seem that Antichrist is not the head of the wicked. For there are not several heads of one body. But the devil is the head of the multitude of the wicked. Therefore Antichrist is not their head.

Obj. 2: Further, Antichrist is a member of the devil. Now the head is distinguished from the members. Therefore Antichrist is not the head of the wicked.

Obj. 3: Further, the head has an influence over the members. But Antichrist has no influence over the wicked who have preceded him. Therefore Antichrist is not the head of the wicked.

On the contrary, A gloss [*St. Gregory, Moral. xv] on Job 21:29, "Ask any of them that go by the way," says: "Whilst he was speaking of the body of all the wicked, suddenly he turned his speech to Antichrist the head of all evil-doers."

I answer that, As was said above (A. 1), in the head are found three things: order, perfection, and the power of influencing. But as regards the order of the body, Antichrist is not said to be the head of the wicked as if his sin had preceded, as the sin of the devil preceded. So likewise he is not called the head of the wicked from the power of influencing, although he will pervert some in his day by exterior persuasion; nevertheless those who were before him were not beguiled into wickedness by him nor have imitated his wickedness. Hence he cannot be called the head of all the wicked in this way, but of some. Therefore it remains to be said that he is the head of all the wicked by reason of the perfection of his wickedness. Hence, on 2 Thess. 2:4, "Showing himself as if he were God," a gloss says: "As in Christ dwelt the fulness of the Godhead, so in Antichrist the fulness of all wickedness." Not indeed as if his humanity were assumed by the devil into unity of person, as the humanity of Christ by the Son of God; but that the devil by suggestion infuses his wickedness more copiously into him than into all others. And in this way all the wicked who have gone before are signs of Antichrist, according to 2 Thess. 2:7, "For the mystery of iniquity already worketh."

Reply Obj. 1: The devil and Antichrist are not two heads, but one; since Antichrist is called the head, inasmuch as the wickedness of the devil is most fully impressed on him. Hence, on 2 Thess. 2:4, "Showing himself as if he were God," a gloss says: "The head of all the wicked, namely the devil, who is king over all the children of pride will be in him." Now he is said to be in him not by personal union, nor by indwelling, since "the Trinity alone dwells in the mind" (as is said De Eccles. Dogm. lxxxiii), but by the effect of wickedness.

Reply Obj. 2: As the head of Christ is God, and yet He is the Head of the Church, as was said above (A. 1, ad 2), so likewise Antichrist is a member of the devil and yet is head of the wicked.

Reply Obj. 3: Antichrist is said to be the head of all the wicked not by a likeness of influence, but by a likeness of perfection. For in him the devil, as it were, brings his wickedness to a head, in the same way that anyone is said to bring his purpose to a head when he executes it. _____

QUESTION 9

OF CHRIST'S KNOWLEDGE IN GENERAL (In Four Articles)

We must now consider Christ's knowledge; concerning which the consideration will be twofold. First, of Christ's knowledge in general; secondly, of each particular kind of knowledge He had.

Under the first head there are four points of inquiry:

(1) Whether Christ had any knowledge besides the Divine?

(2) Whether He had the knowledge which the blessed or comprehensors have?

(3) Whether He had an imprinted or infused knowledge?

(4) Whether He had any acquired knowledge? _____

FIRST ARTICLE [III, Q. 9, Art. 1]

Whether Christ Had Any Knowledge Besides the Divine?

Objection 1: It would seem that in Christ there was no knowledge except the Divine. For knowledge is necessary that things may be known thereby. But by His Divine knowledge Christ knew all things. Therefore any other knowledge would have been superfluous in Him.

Obj. 2: Further, the lesser light is dimmed by the greater. But all created knowledge in comparison with the uncreated knowledge of God is as the lesser to the greater light. Therefore there shone in Christ no other knowledge except the Divine.

Obj. 3: Further, the union of the human nature with the Divine took place in the Person, as is clear from Q. 2, A. 2. Now, according to some there is in Christ a certain "knowledge of the union," whereby Christ knew what belongs to the mystery of the Incarnation more fully than anyone else. Hence, since the personal union contains two natures, it would seem that there are not two knowledges in Christ, but one only, pertaining to both natures.

On the contrary, Ambrose says (De Incarnat. vii): "God assumed the perfection of human nature in the flesh; He took upon Himself the sense of man, but not the swollen sense of the flesh." But created knowledge pertains to the sense of man. Therefore in Christ there was created knowledge.

I answer that, As said above (Q. 5), the Son of God assumed an entire human nature, i.e. not only a body, but also a soul, and not only a sensitive, but also a rational soul. And therefore it behooved Him to have created knowledge, for three reasons. First, on account of the soul's perfection. For the soul, considered in itself, is in potentiality to knowing intelligible things. since it is like "a tablet on which nothing is written," and yet it may be written upon through the possible intellect, whereby it may become all things, as is said De Anima iii, 18. Now what is in potentiality is imperfect unless reduced to act. But it was fitting that the Son of God should assume, not an imperfect, but a perfect human nature, since the whole human race was to be brought back to perfection by its means. Hence it behooved the soul of Christ to be perfected by a knowledge, which would be its proper perfection. And therefore it was necessary that there should be another knowledge in Christ besides the Divine knowledge, otherwise the soul of Christ would have been more imperfect than the souls of the rest of men. Secondly, because, since everything is on account of its operation, as stated De Coel. ii, 17, Christ would have had an intellective soul to no purpose if He had not understood by it; and this pertains to created knowledge. Thirdly, because some created knowledge pertains to the nature of the human soul, viz. that whereby we naturally know first principles; since we are here taking knowledge for any cognition of the human intellect. Now nothing natural was wanting to Christ, since He took the whole human nature, as stated above (Q. 5). And hence the Sixth Council [*Third Council of Constantinople, Act. 4] condemned the opinion of those who denied that in Christ there are two knowledges or wisdoms.

Reply Obj. 1: Christ knew all things with the Divine knowledge by an uncreated operation which is the very Essence of God; since God's understanding is His substance, as the Philosopher proves (Metaph. xii, text. 39). Hence this act could not belong to the human soul of Christ, seeing that it belongs to another nature. Therefore, if there had been no other knowledge in the soul of Christ, it would have known nothing; and thus it would have been assumed to no purpose, since everything is on account of its operation.

Reply Obj. 2: If the two lights are supposed to be in the same order, the lesser is dimmed by the greater, as the light of the sun dims the light of a candle, both being in the class of illuminants. But if we suppose two lights, one of which is in the class of illuminants and the other in the class of illuminated, the lesser light is not dimmed by the greater, but rather is strengthened, as the light of the air by the light of the sun. And in this manner the light of knowledge is not dimmed, but rather is heightened in the soul of Christ by the light of the Divine knowledge, which is "the true light which enlighteneth every man that cometh into this world," as is written John 1:9.

Reply Obj. 3: On the part of what are united we hold there is a knowledge in Christ, both as to His Divine and as to His human nature; so that, by reason of the union whereby there is one hypostasis of God and man, the things of God are attributed to man, and the things of man are attributed to God, as was said above (Q. 3, AA. 1, 6). But on the part of the union itself we cannot admit any knowledge in Christ. For this union is in personal being, and knowledge belongs to person only by reason of a nature. _____

SECOND ARTICLE [III, Q. 9, Art. 2]

Whether Christ Had the Knowledge Which the Blessed or Comprehensors Have?

Objection 1: It would seem that in Christ there was not the knowledge of the blessed or comprehensors. For the knowledge of the blessed is a participation of Divine light, according to Ps. 35:10: "In Thy light we shall see light." Now Christ had not a participated light, but He had the Godhead Itself substantially abiding in Him, according to Col. 2:9: "For in Him dwelleth all the fulness of the Godhead corporeally." Therefore in Christ there was not the knowledge of the blessed.

Obj. 2: Further, the knowledge of the blessed makes them blessed, according to John 17:3: "This is eternal life: that they may know Thee, the only true God, and Jesus Christ Whom Thou hast sent." But this Man was blessed through being united to God in person, according to Ps. 64:5: "Blessed is He Whom Thou hast chosen and taken to Thee." Therefore it is not necessary to suppose the knowledge of the blessed in Him.

Obj. 3: Further, to man belongs a double knowledge—one by nature, one above nature. Now the knowledge of the blessed, which consists in the vision of God, is not natural to man, but above his nature. But in Christ there was another and much higher supernatural knowledge, i.e. the Divine knowledge. Therefore there was no need of the knowledge of the blessed in Christ.

On the contrary, The knowledge of the blessed consists in the knowledge of God. But He knew God fully, even as He was man, according to John 8:55: "I do know Him, and do keep His word." Therefore in Christ there was the knowledge of the blessed.

I answer that, What is in potentiality is reduced to act by what is in act; for that whereby things are heated must itself be hot. Now man is in potentiality to the knowledge of the blessed, which consists in the vision of God; and is ordained to it as to an end; since the rational creature is capable of that blessed knowledge, inasmuch as he is made in the image of God. Now men are brought to this end of beatitude by the humanity of Christ, according to Heb. 2:10: "For it became Him, for Whom are all things, and by Whom are all things, Who had brought many children unto glory, to perfect the author of their salvation by His passion." And hence it was necessary that the beatific knowledge, which consists in the vision of God, should belong to Christ pre-eminently, since the cause ought always to be more efficacious than the effect.

Reply Obj. 1: The Godhead is united to the manhood of Christ in Person, not in essence or nature; yet with the unity of Person remains the distinction of natures. And therefore the soul of Christ, which is a part of human nature, through a light participated from the Divine Nature, is perfected with the beatific knowledge whereby it sees God in essence.

Reply Obj. 2: By the union this Man is blessed with the uncreated beatitude, even as by the union He is God; yet besides the uncreated beatitude it was necessary that there should be in the human nature of Christ a created beatitude, whereby His soul was established in the last end of human nature.

Reply Obj. 3: The beatific vision and knowledge are to some extent above the nature of the rational soul, inasmuch as it cannot reach it of its own strength; but in another way it is in accordance with its nature, inasmuch as it is capable of it by nature, having been made to the likeness of God, as stated above. But the uncreated knowledge is in every way above the nature of the human soul. _____

THIRD ARTICLE [III, Q. 9, Art. 3]

Whether Christ Had an Imprinted or Infused Knowledge?

Objection 1: It would seem that there was not in Christ another infused knowledge besides the beatific knowledge. For all other knowledge compared to the beatific knowledge is like imperfect to perfect. But imperfect knowledge is removed by the presence of perfect knowledge, as the clear "face-to-face" vision removes the enigmatical vision of faith, as is plain from 1 Cor. 13:10, 12. Since, therefore, in Christ there was the beatific knowledge, as stated above (A. 2), it would seem that there could not be any other imprinted knowledge.

Obj. 2: Further, an imperfect mode of cognition disposes towards a more perfect, as opinion, the result of dialectical syllogisms, disposes towards science, which results from demonstrative syllogisms. Now, when perfection is reached, there is no further need of the disposition, even as on reaching the end motion is no longer necessary. Hence, since every created cognition is compared to beatific cognition, as imperfect to perfect and as disposition to its term, it seems that since Christ had beatific knowledge, it was not necessary for Him to have any other knowledge.

Obj. 3: Further, as corporeal matter is in potentiality to sensible forms, so the possible intellect is in potentiality to intelligible forms. Now corporeal matter cannot receive two forms at once, one more perfect and the other less perfect. Therefore neither can the soul receive a double knowledge at once, one more perfect and the other less perfect; and hence the same conclusion as above.

On the contrary, It is written (Col. 2:3) that in Christ "are hid all the treasures of wisdom and knowledge."

I answer that, As stated above (A. 1), it was fitting that the human nature assumed by the Word of God should not be imperfect. Now everything in potentiality is imperfect unless it be reduced to act. But the passive intellect of man is in potentiality to all intelligible things, and it is reduced to act by intelligible species, which are its completive forms, as is plain from what is said De Anima iii, 32, 38. And hence we must admit in the soul of Christ an infused knowledge, inasmuch as the Word of God imprinted upon the soul of Christ, which is personally united to Him, intelligible species of all things to which the possible intellect is in potentiality; even as in the beginning of the creation of things, the Word of God imprinted intelligible species upon the angelic mind, as is clear from Augustine (Gen. ad lit. ii, 8). And therefore, even as in the angels, according to Augustine (Gen. ad lit. iv, 22, 24, 30), there is a double knowledge—one the morning knowledge, whereby they know things in the Word; the other the evening knowledge, whereby they know things in their proper natures by infused species; so likewise, besides the Divine and uncreated knowledge in Christ, there is in His soul a beatific knowledge, whereby He knows the Word, and things in the Word; and an infused or imprinted knowledge, whereby He knows things in their proper nature by intelligible species proportioned to the human mind.

Reply Obj. 1: The imperfect vision of faith is essentially opposed to manifest vision, seeing that it is of the essence of faith to have reference to the unseen, as was said above (II-II, Q. 1, A. 4). But cognition by infused species includes no opposition to beatific cognition. Therefore there is no parity.

Reply Obj. 2: Disposition is referred to perfection in two ways: first, as a way leading to perfection; secondly, as an effect proceeding from perfection; thus matter is disposed by heat to receive the form of fire, and, when this comes, the heat does not cease, but remains as an effect of this form. So, too, opinion caused by a dialectical syllogism is a way to knowledge, which is acquired by demonstration, yet, when this has been acquired, there may still remain the knowledge gained by the dialectical syllogism, following, so to say, the demonstrative knowledge, which is based on the cause, since he who knows the cause is thereby enabled the better to understand the probable signs from which dialectical syllogisms proceed. So likewise in Christ, together with the beatific knowledge, there still remains infused knowledge, not as a way to beatitude, but as strengthened by beatitude.

Reply Obj. 3: The beatific knowledge is not by a species, that is a similitude of the Divine Essence, or of whatever is known in the Divine Essence, as is plain from what has been said in the First Part (Q. 12, A. 2); but it is a knowledge of the Divine Essence immediately, inasmuch as the Divine Essence itself is united to the beatified mind as an intelligible to an intelligent being; and the Divine Essence is a form exceeding the capacity of any creature whatsoever. Hence, together with this super-exceeding form, there is nothing to hinder from being in the rational mind, intelligible species, proportioned to its nature. _____

FOURTH ARTICLE [III, Q. 9, Art. 4]

Whether Christ Had Any Acquired Knowledge?

Objection 1: It would seem that in Christ there was no empiric and acquired knowledge. For whatever befitted Christ, He had most perfectly. Now Christ did not possess acquired knowledge most perfectly, since He did not devote Himself to the study of letters, by which knowledge is acquired in its perfection; for it is said (John 7:15): "The Jews wondered, saying: How doth this Man know letters, having never learned?" Therefore it seems that in Christ there was no acquired knowledge.

Obj. 2: Further, nothing can be added to what is full. But the power of Christ's soul was filled with intelligible species divinely infused, as was said above (A. 3). Therefore no acquired species could accrue to His soul.

Obj. 3: Further, he who already has the habit of knowledge, acquires no new habit, through what he receives from the senses (otherwise two forms of the same species would be in the same thing together); but the habit which previously existed is strengthened and increased. Therefore, since Christ had the habit of infused knowledge, it does not seem that He acquired a new knowledge through what He perceived by the senses.

On the contrary, It is written (Heb. 5:8): "Whereas . . . He was the Son of God, He learned obedience by the things which He suffered," i.e. "experienced," says a gloss. Therefore there was in the soul of Christ an empiric knowledge, which is acquired knowledge.

I answer that, As is plain from A. 1, nothing that God planted in our nature was wanting to the human nature assumed by the Word of God. Now it is manifest that God planted in human nature not only a passive, but an active intellect. Hence it is necessary to say that in the soul of Christ there was not merely a passive, but also an active intellect. But if in other things God and nature make nothing in vain, as the Philosopher says (De Coel. i, 31; ii, 59), still less in the soul of Christ is there anything in vain. Now what has not its proper operation is useless, as is said in De Coel. ii, 17. Now the proper operation of the active intellect is to make intelligible species in act, by abstracting them from phantasms; hence, it is said (De Anima iii, 18) that the active intellect is that "whereby everything is made actual." And thus it is necessary to say that in Christ there were intelligible species received in the passive intellect by the action of the active intellect—which means that there was acquired knowledge in Him, which some call empiric. And hence, although I wrote differently (Sent. iii, D, xiv, A. 3; D, xviii, A. 3), it must be said that in Christ there was acquired knowledge, which is properly knowledge in a human fashion, both as regards the subject receiving and as regards the active cause. For such knowledge springs from Christ's active intellect, which is natural to the human soul. But infused knowledge is attributed to the soul, on account of a light infused from on high, and this manner of knowing is proportioned to the angelic nature. But the beatific knowledge, whereby the very Essence of God is seen, is proper and natural to God alone, as was said in the First Part (Q. 12, A. 4).

Reply Obj. 1: Since there is a twofold way of acquiring knowledge—by discovery and by being taught—the way of discovery is the higher, and the way of being taught is secondary. Hence it is said (Ethic. i, 4): "He indeed is the best who knows everything by himself: yet he is good who obeys him that speaks aright." And hence it was more fitting for Christ to possess a knowledge acquired by discovery than by being taught, especially since He was given to be the Teacher of all, according to Joel 2:23: "Be joyful in the Lord your God, because He hath given you a Teacher of justice."

Reply Obj. 2: The human mind has two relations—one to higher things, and in this respect the soul of Christ was full of the infused knowledge. The other relation is to lower things, i.e. to phantasms, which naturally move the human mind by virtue of the active intellect. Now it was necessary that even in this respect the soul of Christ should be filled with knowledge, not that the first fulness was insufficient for the human mind in itself, but that it behooved it to be also perfected with regard to phantasms.

Reply Obj. 3: Acquired and infused habits are not to be classed together; for the habit of knowledge is acquired by the relation of the human mind to phantasms; hence, another habit of the same kind cannot be again acquired. But the habit of infused knowledge is of a different nature, as coming down to the soul from on high, and not from phantasms. And hence there is no parity between these habits. _____

QUESTION 10

OF THE BEATIFIC KNOWLEDGE OF CHRIST'S SOUL (In Four Articles)

Now we must consider each of the aforesaid knowledges. Since, however, we have treated of the Divine knowledge in the First Part (Q. 14), it now remains to speak of the three others: (1) of the beatific knowledge; (2) of the infused knowledge; (3) of the acquired knowledge.

But again, because much has been said in the First Part (Q. 12) of the beatific knowledge, which consists in the vision of God, we shall speak here only of such things as belong properly to the soul of Christ. Under this head there are four points of inquiry:

(1) Whether the soul of Christ comprehended the Word or the Divine Essence?

(2) Whether it knew all things in the Word?

(3) Whether the soul of Christ knew the infinite in the Word?

(4) Whether it saw the Word or the Divine Essence clearer than did any other creature? _____

FIRST ARTICLE [III, Q. 10, Art. 1]

Whether the Soul of Christ Comprehended the Word or the Divine Essence?

Objection 1: It would seem that the soul of Christ comprehended and comprehends the Word or Divine Essence. For Isidore says (De Summo Bono i, 3) that "the Trinity is known only to Itself and to the Man assumed." Therefore the Man assumed communicates with the Holy Trinity in that knowledge of Itself which is proper to the Trinity. Now this is the knowledge of comprehension. Therefore the soul of Christ comprehends the Divine Essence.

Obj. 2: Further, to be united to God in personal being is greater than to be united by vision. But as Damascene says (De Fide Orth. iii, 6), "the whole Godhead in one Person is united to the human nature in Christ." Therefore much more is the whole Divine Nature seen by the soul of Christ; and hence it would seem that the soul of Christ comprehended the Divine Essence.

Obj. 3: Further, what belongs by nature to the Son of God belongs by grace to the Son of Man, as Augustine says (De Trin. i, 13). But to comprehend the Divine Essence belongs by nature to the Son of God. Therefore it belongs by grace to the Son of Man; and thus it seems that the soul of Christ comprehended the Divine Essence by grace.

On the contrary, Augustine says (Qq. lxxxiii, qu. 14): "Whatsoever comprehends itself is finite to itself." But the Divine Essence is not finite with respect to the soul of Christ, since It infinitely exceeds it. Therefore the soul of Christ does not comprehend the Word.

I answer that, As is plain from Q. 2, AA. 1, 6, the union of the two natures in the Person of Christ took place in such a way that the properties of both natures remained unconfused, i.e. "the uncreated remained uncreated, and the created remained within the limits of the creature," as Damascene says (De Fide Orth. iii, 3, 4). Now it is impossible for any creature to comprehend the Divine Essence, as was shown in the First Part (Q. 12, AA. 1, 4, 7), seeing that the infinite is not comprehended by the finite. And hence it must be said that the soul of Christ nowise comprehends the Divine Essence.

Reply Obj. 1: The Man assumed is reckoned with the Divine Trinity in the knowledge of Itself, not indeed as regards comprehension, but by reason of a certain most excellent knowledge above the rest of creatures.

Reply Obj. 2: Not even in the union by personal being does the human nature comprehend the Word of God or the Divine Nature, for although it was wholly united to the human nature in the one Person of the Son, yet the whole power of the Godhead was not circumscribed by the human nature. Hence Augustine says (Ep. ad Volusian. cxxxvii): "I would have you know that it is not the Christian doctrine that God was united to flesh in such a manner as to quit or lose the care of the world's government, neither did He narrow or reduce it when He transferred it to that little body." So likewise the soul of Christ sees the whole Essence of God, yet does not comprehend It; since it does not see It totally, i.e. not as perfectly as It is knowable, as was said in the First Part (Q. 12, A. 7).

Reply Obj. 3: This saying of Augustine is to be understood of the grace of union, by reason of which all that is said of the Son of God in His Divine Nature is also said of the Son of Man on account of the identity of suppositum. And in this way it may be said that the Son of Man is a comprehensor of the Divine Essence, not indeed by His soul, but in His Divine Nature; even as we may also say that the Son of Man is the Creator. _____

SECOND ARTICLE [III, Q. 10, Art. 2]

Whether the Son of God Knew All Things in the Word?

Obj. 1: It would seem that the soul of Christ does not know all things in the Word. For it is written (Mk. 13:32): "But of that day or hour no man knoweth, neither the angels in heaven nor the Son, but the Father." Therefore He does not know all things in the Word.

Obj. 2: Further, the more perfectly anyone knows a principle the more he knows in the principle. But God sees His Essence more perfectly than the soul of Christ does. Therefore He knows more than the soul of Christ knows in the Word. Therefore the soul of Christ does not know all things in the Word.

Obj. 3: Further, the extent depends on the number of things known. If, therefore, the soul of Christ knew in the Word all that the Word knows, it would follow that the knowledge of the soul of Christ would equal the Divine knowledge, i.e. the created would equal the uncreated, which is impossible.

On the contrary, on Apoc. 5:12, "The Lamb that was slain is worthy to receive . . . divinity and wisdom," a gloss says, i.e. "the knowledge of all things."

I answer that, When it is inquired whether Christ knows all things in the Word, "all things" may be taken in two ways: First, properly, to stand for all that in any way whatsoever is, will be, or was done, said, or thought, by whomsoever and at any time. And in this way it must be said that the soul of Christ knows all things in the Word. For every created intellect knows in the Word, not all simply, but so many more things the more perfectly it sees the Word. Yet no beatified intellect fails to know in the Word whatever pertains to itself. Now to Christ and to His dignity all things to some extent belong, inasmuch as all things are subject to Him. Moreover, He has been appointed Judge of all by God, "because He is the Son of Man," as is said John 5:27; and therefore the soul of Christ knows in the Word all things existing in whatever time, and the thoughts of men, of which He is the Judge, so that what is said of Him (John 2:25), "For He knew what was in man," can be understood not merely of the Divine knowledge, but also of His soul's knowledge, which it had in the Word. Secondly, "all things" may be taken widely, as extending not merely to such things as are in act at some time, but even to such things as are in potentiality, and never have been nor ever will be reduced to act. Now some of these are in the Divine power alone, and not all of these does the soul of Christ know in the Word. For this would be to comprehend all that God could do, which would be to comprehend the Divine power, and, consequently, the Divine Essence. For every power is known from the knowledge of all it can do. Some, however, are not only in the power of God, but also in the power of the creature; and all of these the soul of Christ knows in the Word; for it comprehends in the Word the essence of every creature, and, consequently, its power and virtue, and all things that are in the power of the creature.

Reply Obj. 1: Arius and Eunomius understood this saying, not of the knowledge of the soul, which they did not hold to be in Christ, as was said above (Q. 9, A. 1), but of the Divine knowledge of the Son, Whom they held to be less than the Father as regards knowledge. But this will not stand, since all things were made by the Word of God, as is said John 1:3, and, amongst other things, all times were made by Him. Now He is not ignorant of anything that was made by Him.

He is said, therefore, not to know the day and the hour of the Judgment, for that He does not make it known, since, on being asked by the apostles (Acts 1:7), He was unwilling to reveal it; and, on the contrary, we read (Gen. 22:12): "Now I know that thou fearest God," i.e. "Now I have made thee know." But the Father is said to know, because He imparted this knowledge to the Son. Hence, by saying "but the Father," we are given to understand that the Son knows, not merely in the Divine Nature, but also in the human, because, as Chrysostom argues (Hom. lxxviii in Matth.), if it is given to Christ as man to know how to judge—which is greater—much more is it given to Him to know the less, viz. the time of Judgment. Origen, however (in Matth. Tract. xxx), expounds it of His body, which is the Church, which is ignorant of this time. Lastly, some say this is to be understood of the adoptive, and not of the natural Son of God.

Reply Obj. 2: God knows His Essence so much the more perfectly than the soul of Christ, as He comprehends it. And hence He knows all things, not merely whatever are in act at any time, which things He is said to know by knowledge of vision, but also what ever He Himself can do, which He is said to know by simple intelligence, as was shown in the First Part (Q. 14, A. 9). Therefore the soul of Christ knows all things that God knows in Himself by the knowledge of vision, but not all that God knows in Himself by knowledge of simple intelligence; and thus in Himself God knows many more things than the soul of Christ.

Reply Obj. 3: The extent of knowledge depends not merely on the number of knowable things, but also on the clearness of the knowledge. Therefore, although the knowledge of the soul of Christ which He has in the Word is equal to the knowledge of vision as regards the number of things known, nevertheless the knowledge of God infinitely exceeds the knowledge of the soul of Christ in clearness of cognition, since the uncreated light of the Divine intellect infinitely exceeds any created light received by the soul of Christ; although, absolutely speaking, the Divine knowledge exceeds the knowledge of the soul of Christ, not only as regards the mode of knowing, but also as regards the number of things known, as was stated above. _____

THIRD ARTICLE [III, Q. 10, Art. 3]

Whether the Soul of Christ Can Know the Infinite in the Word?

Objection 1: It would seem that the soul of Christ cannot know the infinite in the Word. For that the infinite should be known is repugnant to the definition of the infinite which (Phys. iii, 63) is said to be that "from which, however much we may take, there always remains something to be taken." But it is impossible for the definition to be separated from the thing defined, since this would mean that contradictories exist together. Therefore it is impossible that the soul of Christ knows the infinite.

Obj. 2: Further, the knowledge of the infinite is infinite. But the knowledge of the soul of Christ cannot be infinite, because its capacity is finite, since it is created. Therefore the soul of Christ cannot know the infinite.

Obj. 3: Further, there can be nothing greater than the infinite. But more is contained in the Divine knowledge, absolutely speaking, than in the knowledge of Christ's soul, as stated above (A. 2). Therefore the soul of Christ does not know the infinite.

On the contrary, The soul of Christ knows all its power and all it can do. Now it can cleanse infinite sins, according to 1 John 2:2: "He is the propitiation for our sins, and not for ours only, but also for those of the whole world." Therefore the soul of Christ knows the infinite.

I answer that, Knowledge regards only being, since being and truth are convertible. Now a thing is said to be a being in two ways: First, simply, i.e. whatever is a being in act; secondly, relatively, i.e. whatever is a being in potentiality. And because, as is said Metaph. ix, 20, everything is known as it is in act, and not as it is in potentiality, knowledge primarily and essentially regards being in act, and secondarily regards being in potentiality, which is not knowable of itself, but inasmuch as that in whose power it exists is known. Hence, with regard to the first mode of knowledge, the soul of Christ does not know the infinite. Because there is not an infinite number in act, even though we were to reckon all that are in act at any time whatsoever, since the state of generation and corruption will not last for ever: consequently there is a certain number not only of things lacking generation and corruption, but also of things capable of generation and corruption. But with regard to the other mode of knowing, the soul of Christ knows infinite things in the Word, for it knows, as stated above (A. 2), all that is in the power of the creature. Hence, since in the power of the creature there is an infinite number of things, it knows the infinite, as it were, by a certain knowledge of simple intelligence, and not by a knowledge of vision.

Reply Obj. 1: As we said in the First Part (Q. 8, A. 1), the infinite is taken in two ways. First, on the part of a form, and thus we have the negatively infinite, i.e. a form or act not limited by being received into matter or a subject; and this infinite of itself is most knowable on account of the perfection of the act, although it is not comprehensible by the finite power of the creature; for thus God is said to be infinite. And this infinite the soul of Christ knows, yet does not comprehend. Secondly, there is the infinite as regards matter, which is taken privatively, i.e. inasmuch as it has not the form it ought naturally to have, and in this way we have infinite in quantity. Now such an infinite of itself, is unknown: inasmuch as it is, as it were, matter with privation of form as is said Phys. iii, 65. But all knowledge is by form or act. Therefore if this infinite is to be known according to its mode of being, it cannot be known. For its mode is that part be taken after part, as is said Phys. iii, 62, 63. And in this way it is true that, if we take something from it, i.e. taking part after part, there always remains something to be taken. But as material things can be received by the intellect immaterially, and many things unitedly, so can infinite things be received by the intellect, not after the manner of infinite, but finitely; and thus what are in themselves infinite are, in the intellect of the knower, finite. And in this way the soul of Christ knows an infinite number of things, inasmuch as it knows them not by discoursing from one to another, but in a certain unity, i.e. in any creature in whose potentiality infinite things exist, and principally in the Word Himself.

Reply Obj. 2: There is nothing to hinder a thing from being infinite in one way and finite in another, as when in quantities we imagine a surface infinite in length and finite in breadth. Hence, if there were an infinite number of men, they would have a relative infinity, i.e. in multitude; but, as regards the essence, they would be finite, since the essence of all would be limited to one specific nature. But what is simply infinite in its essence is God, as was said in the First Part (Q. 7, A. 2). Now the proper object of the intellect is "what a thing is," as is said De Anima iii, 26, to which pertains the notion of the species. And thus the soul of Christ, since it has a finite capacity, attains to, but does not comprehend, what is simply infinite in essence, as stated above (A. 1). But the infinite in potentiality which is in creatures can be comprehended by the soul of Christ, since it is compared to that soul according to its essence, in which respect it is not infinite. For even our intellect understands a universal—for example, the nature of a genus or species, which in a manner has infinity, inasmuch as it can be predicated of an infinite number.

Reply Obj. 3: That which is infinite in every way can be but one. Hence the Philosopher says (De Coel. i, 2, 3) that, since bodies have dimensions in every part, there cannot be several infinite bodies. Yet if anything were infinite in one way only, nothing would hinder the existence of several such infinite things; as if we were to suppose several lines of infinite length drawn on a surface of finite breadth. Hence, because infinitude is not a substance, but is accidental to things that are said to be infinite, as the Philosopher says (Phys. iii, 37, 38); as the infinite is multiplied by different subjects, so, too, a property of the infinite must be multiplied, in such a way that it belongs to each of them according to that particular subject. Now it is a property of the infinite that nothing is greater than it. Hence, if we take one infinite line, there is nothing greater in it than the infinite; so, too, if we take any one of other infinite lines, it is plain that each has infinite parts. Therefore of necessity in this particular line there is nothing greater than all these infinite parts; yet in another or a third line there will be more infinite parts besides these. We observe this in numbers also, for the species of even numbers are infinite, and likewise the species of odd numbers are infinite; yet there are more even and odd numbers than even. And thus it must be said that nothing is greater than the simply and in every way infinite; but than the infinite which is limited in some respect, nothing is greater in that order; yet we may suppose something greater outside that order. In this way, therefore, there are infinite things in the potentiality of the creature, and yet there are more in the power of God than in the potentiality of the creature. So, too, the soul of Christ knows infinite things by the knowledge of simple intelligence; yet God knows more by this manner of knowledge or understanding. _____

FOURTH ARTICLE [III, Q. 10, Art. 4]

Whether the Soul of Christ Sees the Word or the Divine Essence More Clearly Than Does Any Other Creature?

Objection 1: It would seem that the soul of Christ does not see the Word more perfectly than does any other creature. For the perfection of knowledge depends upon the medium of knowing; as the knowledge we have by means of a demonstrative syllogism is more perfect than that which we have by means of a probable syllogism. But all the blessed see the Word immediately in the Divine Essence Itself, as was said in the First Part (Q. 12, A. 2). Therefore the soul of Christ does not see the Word more perfectly than any other creature.

Obj. 2: Further, the perfection of vision does not exceed the power of seeing. But the rational power of a soul such as is the soul of Christ is below the intellective power of an angel, as is plain from Dionysius (Coel. Hier. iv). Therefore the soul of Christ did not see the Word more perfectly than the angels.

Obj. 3: Further, God sees His Word infinitely more perfectly than does the soul of Christ. Hence there are infinite possible mediate degrees between the manner in which God sees His Word, and the manner in which the soul of Christ sees the Word. Therefore we cannot assert that the soul of Christ sees the Word or the Divine Essence more perfectly than does every other creature.

On the contrary, The Apostle says (Eph. 1:20, 21) that God set Christ "on His right hand in the heavenly places, above all principality and power and virtue and dominion and every name that is named not only in this world, but also in that which is to come." But in that heavenly glory the higher anyone is the more perfectly does he know God. Therefore the soul of Christ sees God more perfectly than does any other creature.

I answer that, The vision of the Divine Essence is granted to all the blessed by a partaking of the Divine light which is shed upon them from the fountain of the Word of God, according to Ecclus. 1:5: "The Word of God on high is the fountain of Wisdom." Now the soul of Christ, since it is united to the Word in person, is more closely joined to the Word of God than any other creature. Hence it more fully receives the light in which God is seen by the Word Himself than any other creature. And therefore more perfectly than the rest of creatures it sees the First Truth itself, which is the Essence of God; hence it is written (John 1:14): "And we saw His glory, the glory as it were of the Only-begotten of the Father," "full" not only of "grace" but also of "truth."

Reply Obj. 1: Perfection of knowledge, on the part of the thing known, depends on the medium; but as regards the knower, it depends on the power or habit. And hence it is that even amongst men one sees a conclusion in a medium more perfectly than another does. And in this way the soul of Christ, which is filled with a more abundant light, knows the Divine Essence more perfectly than do the other blessed, although all see the Divine Essence in itself.

Reply Obj. 2: The vision of the Divine Essence exceeds the natural power of any creature, as was said in the First Part (Q. 12, A. 4). And hence the degrees thereof depend rather on the order of grace in which Christ is supreme, than on the order of nature, in which the angelic nature is placed before the human.

Reply Obj. 3: As stated above (Q. 7, A. 12), there cannot be a greater grace than the grace of Christ with respect to the union with the Word; and the same is to be said of the perfection of the Divine vision; although, absolutely speaking, there could be a higher and more sublime degree by the infinity of the Divine power. _____

QUESTION 11

OF THE KNOWLEDGE IMPRINTED OR INFUSED IN THE SOUL OF CHRIST (In Six Articles)

We must now consider the knowledge imprinted or infused in the soul of Christ, and under this head there are six points of inquiry:

(1) Whether Christ knows all things by this knowledge?

(2) Whether He could use this knowledge by turning to phantasms?

(3) Whether this knowledge was collative?

(4) Of the comparison of this knowledge with the angelic knowledge;

(5) Whether it was a habitual knowledge?

(6) Whether it was distinguished by various habits? _____

FIRST ARTICLE [III, Q. 11, Art. 1]

Whether by This Imprinted or Infused Knowledge Christ Knew All Things?

Objection 1: It would seem that by this knowledge Christ did not know all things. For this knowledge is imprinted upon Christ for the perfection of the passive intellect. Now the passive intellect of the human soul does not seem to be in potentiality to all things simply, but only to those things with regard to which it can be reduced to act by the active intellect, which is its proper motor; and these are knowable by natural reason. Therefore by this knowledge Christ did not know what exceeded the natural reason.

Obj. 2: Further, phantasms are to the human intellect as colors to sight, as is said De Anima iii, 18, 31, 39. But it does not pertain to the perfection of the power of seeing to know what is without color. Therefore it does not pertain to the perfection of human intellect to know things of which there are no phantasms, such as separate substances. Hence, since this knowledge was in Christ for the perfection of His intellective soul, it seems that by this knowledge He did not know separate substances.

Obj. 3: Further, it does not belong to the perfection of the intellect to know singulars. Hence it would seem that by this knowledge the soul of Christ did not know singulars.

On the contrary, It is written (Isa. 11:2) that "the Spirit of wisdom and understanding, of knowledge and counsel shall fill Him [*Vulg.: 'The Spirit of the Lord shall rest upon Him, the Spirit of wisdom and understanding, the Spirit of counsel . . . the Spirit of knowledge . . . '; cf. Ecclus. 15:5," under which are included all that may be known; for the knowledge of all Divine things belongs to wisdom, the knowledge of all immaterial things to understanding, the knowledge of all conclusions to knowledge (scientia), the knowledge of all practical things to counsel. Hence it would seem that by this knowledge Christ had the knowledge of all things.

I answer that, As was said above (Q. 9, A. 1), it was fitting that the soul of Christ should be wholly perfected by having each of its powers reduced to act. Now it must be borne in mind that in the human soul, as in every creature, there is a double passive power: one in comparison with a natural agent; the other in comparison with the first agent, which can reduce any creature to a higher act than a natural agent can reduce it, and this is usually called the obediential power of a creature. Now both powers of Christ's soul were reduced to act by this divinely imprinted knowledge. And hence, by it the soul of Christ knew: First, whatever can be known by force of a man's active intellect, e.g. whatever pertains to human sciences; secondly, by this knowledge Christ knew all things made known to man by Divine revelation, whether they belong to the gift of wisdom or the gift of prophecy, or any other gift of the Holy Ghost; since the soul of Christ knew these things more fully and completely than others. Yet He did not know the Essence of God by this knowledge, but by the first alone, of which we spoke above (Q. 10).

Reply Obj. 1: This reason refers to the natural power of an intellective soul in comparison with its natural agent, which is the active intellect.

Reply Obj. 2: The human soul in the state of this life, since it is somewhat fettered by the body, so as to be unable to understand without phantasms, cannot understand separate substances. But after the state of this life the separated soul will be able, in a measure, to know separate substances by itself, as was said in the First Part (Q. 89, AA. 1, 2), and this is especially clear as regards the souls of the blessed. Now before His Passion, Christ was not merely a wayfarer but also a comprehensor; hence His soul could know separate substances in the same way that a separated soul could.

Reply Obj. 3: The knowledge of singulars pertains to the perfection of the intellective soul, not in speculative knowledge, but in practical knowledge, which is imperfect without the knowledge of singulars, in which operations exist, as is said _Ethic._ vi, 7. Hence for prudence are required the remembrance of past things, knowledge of present things, and foresight of future things, as Tully says (De Invent. ii). Therefore, since Christ had the fulness of prudence by the gift of counsel, He consequently knew all singular things—present, past, and future. _____

SECOND ARTICLE [III, Q. 11, Art. 2]

Whether Christ Could Use This Knowledge by Turning to Phantasms?

Objection 1: It would seem that the soul of Christ could not understand by this knowledge except by turning to phantasms, because, as is stated De Anima iii, 18, 31, 39, phantasms are compared to man's intellective soul as colors to sight. But Christ's power of seeing could not become actual save by turning to colors. Therefore His intellective soul could understand nothing except by turning to phantasms.

Obj. 2: Further, Christ's soul is of the same nature as ours. otherwise He would not be of the same species as we, contrary to what the Apostle says (Phil. 2:7) " . . . being made in the likeness of men." But our soul cannot understand except by turning to phantasms. Hence, neither can Christ's soul otherwise understand.

Obj. 3: Further, senses are given to man to help his intellect. Hence, if the soul of Christ could understand without turning to phantasms, which arise in the senses, it would follow that in the soul of Christ the senses were useless, which is not fitting. Therefore it seems that the soul of Christ can only understand by turning to phantasms.

On the contrary, The soul of Christ knew certain things which could not be known by the senses, viz. separate substances. Therefore it could understand without turning to phantasms.

I answer that, In the state before His Passion Christ was at the same time a wayfarer and a comprehensor, as will be more clearly shown (Q. 15, A. 10). Especially had He the conditions of a wayfarer on the part of the body, which was passible; but the conditions of a comprehensor He had chiefly on the part of the soul. Now this is the condition of the soul of a comprehensor, viz. that it is nowise subject to its body, or dependent upon it, but wholly dominates it. Hence after the resurrection glory will flow from the soul to the body. But the soul of man on earth needs to turn to phantasms, because it is fettered by the body and in a measure subject to and dependent upon it. And hence the blessed both before and after the resurrection can understand without turning to phantasms. And this must be said of the soul of Christ, which had fully the capabilities of a comprehensor.

Reply Obj. 1: This likeness which the Philosopher asserts is not with regard to everything. For it is manifest that the end of the power of seeing is to know colors; but the end of the intellective power is not to know phantasms, but to know intelligible species, which it apprehends from and in phantasms, according to the state of the present life. Therefore there is a likeness in respect of what both powers regard, but not in respect of that in which the condition of both powers is terminated. Now nothing prevents a thing in different states from reaching its end by different ways: albeit there is never but one proper end of a thing. Hence, although the sight knows nothing without color; nevertheless in a certain state the intellect can know without phantasms, but not without intelligible species.

Reply Obj. 2: Although the soul of Christ was of the same nature as our souls, yet it had a state which our souls have not yet in fact, but only in hope, i.e. the state of comprehension.

Reply Obj. 3: Although the soul of Christ could understand without turning to phantasms, yet it could also understand by turning to phantasms. Hence the senses were not useless in it; especially as the senses are not afforded to man solely for intellectual knowledge, but for the need of animal life. _____

THIRD ARTICLE [III, Q. 11, Art. 3]

Whether This Knowledge Is Collative?

Objection 1: It would seem that the soul of Christ had not this knowledge by way of comparison. For Damascene says (De Fide Orth. iii, 14): "We do not uphold counsel or choice in Christ." Now these things are withheld from Christ only inasmuch as they imply comparison and discursion. Therefore it seems that there was no collative or discursive knowledge in Christ.

Obj. 2: Further, man needs comparison and discursion of reason in order to find out the unknown. But the soul of Christ knew everything, as was said above (Q. 10, A. 2). Hence there was no discursive or collative knowledge in Him.

Obj. 3: Further, the knowledge in Christ's soul was like that of comprehensors, who are likened to the angels, according to Matt. 22:30. Now there is no collative or discursive knowledge in the angels, as Dionysius shows (Div. Nom. vii). Therefore there was no discursive or collative knowledge in the soul of Christ.

On the contrary, Christ had a rational soul, as was shown (Q. 5, A. 4). Now the proper operation of a rational soul consists in comparison and discursion from one thing to another. Therefore there was collative and discursive knowledge in Christ.

I answer that, Knowledge may be discursive or collative in two ways. First, in the acquisition of the knowledge, as happens to us, who proceed from one thing to the knowledge of another, as from causes to effects, and conversely. And in this way the knowledge in Christ's soul was not discursive or collative, since this knowledge which we are now considering was divinely infused, and not acquired by a process of reasoning. Secondly, knowledge may be called discursive or collative in use; as at times those who know, reason from cause to effect, not in order to learn anew, but wishing to use the knowledge they have. And in this way the knowledge in Christ's soul could be collative or discursive; since it could conclude one thing from another, as it pleased, as in Matt. 17:24, 25, when our Lord asked Peter: "Of whom do the kings of the earth receive tribute, of their own children, or of strangers?" On Peter replying: "Of strangers," He concluded: "Then the children are free."

Reply Obj. 1: From Christ is excluded that counsel which is with doubt; and consequently choice, which essentially includes such counsel; but the practice of using counsel is not excluded from Christ.

Reply Obj. 2: This reason rests upon discursion and comparison, as used to acquire knowledge.

Reply Obj. 3: The blessed are likened to the angels in the gifts of graces; yet there still remains the difference of natures. And hence to use comparison and discursion is connatural to the souls of the blessed, but not to angels. _____

FOURTH ARTICLE [III, Q. 11, Art. 4]

Whether in Christ This Knowledge Was Greater Than the Knowledge of the Angels?

Objection 1: It would seem that this knowledge was not greater in Christ than in the angels. For perfection is proportioned to the thing perfected. But the human soul in the order of nature is below the angelic nature. Therefore since the knowledge we are now speaking of is imprinted upon Christ's soul for its perfection, it seems that this knowledge is less than the knowledge by which the angelic nature is perfected.

Obj. 2: Further, the knowledge of Christ's soul was in a measure comparative and discursive, which cannot be said of the angelic knowledge. Therefore the knowledge of Christ's soul was less than the knowledge of the angels.

Obj. 3: Further, the more immaterial knowledge is, the greater it is. But the knowledge of the angels is more immaterial than the knowledge of Christ's soul, since the soul of Christ is the act of a body, and turns to phantasms, which cannot be said of the angels. Therefore the knowledge of angels is greater than the knowledge of Christ's soul.

On the contrary, The Apostle says (Heb. 2:9): "For we see Jesus, Who was made a little lower than the angels, for the suffering of death, crowned with glory and honor"; from which it is plain that Christ is said to be lower than the angels only in regard to the suffering of death. And hence, not in knowledge.

I answer that, The knowledge imprinted on Christ's soul may be looked at in two ways: First, as regards what it has from the inflowing cause; secondly, as regards what it has from the subject receiving it. Now with regard to the first, the knowledge imprinted upon the soul of Christ was more excellent than the knowledge of the angels, both in the number of things known and in the certainty of the knowledge; since the spiritual light, which is imprinted on the soul of Christ, is much more excellent than the light which pertains to the angelic nature. But as regards the second, the knowledge imprinted on the soul of Christ is less than the angelic knowledge, in the manner of knowing that is natural to the human soul, i.e. by turning to phantasms, and by comparison and discursion.

And hereby the reply to the objections is made clear. _____

FIFTH ARTICLE [III, Q. 11, Art. 5]

Whether This Knowledge Was Habitual?

Objection 1: It would seem that in Christ there was no habitual knowledge. For it has been said (Q. 9, A. 1) that the highest perfection of knowledge befitted Christ's soul. But the perfection of an actually existing knowledge is greater than that of a potentially or habitually existing knowledge. Therefore it was fitting for Him to know all things actually. Therefore He had not habitual knowledge.

Obj. 2: Further, since habits are ordained to acts, a habitual knowledge which is never reduced to act would seem useless. Now, since Christ knew all things, as was said (Q. 10, A. 2), He could not have considered all things actually, thinking over one after another, since the infinite cannot be passed over by enumeration. Therefore the habitual knowledge of certain things would have been useless to Him—which is unfitting. Therefore He had an actual and not a habitual knowledge of what He knew.

Obj. 3: Further, habitual knowledge is a perfection of the knower. But perfection is more noble than the thing perfected. If, therefore, in the soul of Christ there was any created habit of knowledge, it would follow that this created thing was nobler than the soul of Christ. Therefore there was no habitual knowledge in Christ's soul.

On the contrary, The knowledge of Christ we are now speaking about was univocal with our knowledge, even as His soul was of the same species as ours. But our knowledge is in the genus of habit. Therefore the knowledge of Christ was habitual.

I answer that, As stated above (A. 4), the mode of the knowledge impressed on the soul of Christ befitted the subject receiving it. For the received is in the recipient after the mode of the recipient. Now the connatural mode of the human soul is that it should understand sometimes actually, and sometimes potentially. But the medium between a pure power and a completed act is a habit: and extremes and medium are of the same genus. Thus it is plain that it is the connatural mode of the human soul to receive knowledge as a habit. Hence it must be said that the knowledge imprinted on the soul of Christ was habitual, for He could use it when He pleased.

Reply Obj. 1: In Christ's soul there was a twofold knowledge—each most perfect of its kind: the first exceeding the mode of human nature, as by it He saw the Essence of God, and other things in It, and this was the most perfect, simply. Nor was this knowledge habitual, but actual with respect to everything He knew in this way. But the second knowledge was in Christ in a manner proportioned to human nature, i.e. inasmuch as He knew things by species divinely imprinted upon Him, and of this knowledge we are now speaking. Now this knowledge was not most perfect, simply, but merely in the genus of human knowledge; hence it did not behoove it to be always in act.

Reply Obj. 2: Habits are reduced to act by the command of the will, since a habit is that "with which we act when we wish." Now the will is indeterminate in regard to infinite things. Yet it is not useless, even when it does not actually tend to all; provided it actually tends to everything in fitting place and time. And hence neither is a habit useless, even if all that it extends to is not reduced to act; provided that that which befits the due end of the will be reduced to act according as the matter in hand and the time require.

Reply Obj. 3: Goodness and being are taken in two ways: First, simply; and thus a substance, which subsists in its being and goodness, is a good and a being; secondly, being and goodness are taken relatively, and in this way an accident is a being and a good, not that it has being and goodness, but that its subject is a being and a good. And hence habitual knowledge is not simply better or more excellent than the soul of Christ; but relatively, since the whole goodness of habitual knowledge is added to the goodness of the subject. _____

SIXTH ARTICLE [III, Q. 11, Art. 6]

Whether This Knowledge Was Distinguished by Divers Habits?

Objection 1: It would seem that in the soul of Christ there was only one habit of knowledge. For the more perfect knowledge is, the more united it is; hence the higher angels understand by the more universal forms, as was said in the First Part (Q. 55, A. 3). Now Christ's knowledge was most perfect. Therefore it was most one. Therefore it was not distinguished by several habits.

Obj. 2: Further, our faith is derived from Christ's knowledge; hence it is written (Heb. 12:2): "Looking on Jesus the author and finisher of faith." But there is only one habit of faith about all things believed, as was said in the Second Part (II-II, Q. 4, A. 6). Much more, therefore, was there only one habit of knowledge in Christ.

Obj. 3: Further, knowledge is distinguished by the divers formalities of knowable things. But the soul of Christ knew everything under one formality, i.e. by a divinely infused light. Therefore in Christ there was only one habit of knowledge.

On the contrary, It is written (Zech. 3:9) that on "one" stone, i.e. Christ, "there are seven eyes." Now by the eye is understood knowledge. Therefore it would seem that in Christ there were several habits of knowledge.

I answer that, As stated above (AA. 4, 5), the knowledge imprinted on Christ's soul has a mode connatural to a human soul. Now it is connatural to a human soul to receive species of a lesser universality than the angels receive; so that it knows different specific natures by different intelligible species. But it so happens that we have different habits of knowledge, because there are different classes of knowable things, inasmuch as what are in one genus are known by one habit; thus it is said (Poster. i, 42) that "one science is of one class of object." And hence the knowledge imprinted on Christ's soul was distinguished by different habits.

Reply Obj. 1: As was said (A. 4), the knowledge of Christ's soul is most perfect, and exceeds the knowledge of angels with regard to what is in it on the part of God's gift; but it is below the angelic knowledge as regards the mode of the recipient. And it pertains to this mode that this knowledge is distinguished by various habits, inasmuch as it regards more particular species.

Reply Obj. 2: Our faith rests upon the First Truth; and hence Christ is the author of our faith by the Divine knowledge, which is simply one.

Reply Obj. 3: The divinely infused light is the common formality for understanding what is divinely revealed, as the light of the active intellect is with regard to what is naturally known. Hence, in the soul of Christ there must be the proper species of singular things, in order to know each with proper knowledge; and in this way there must be divers habits of knowledge in Christ's soul, as stated above. _____

QUESTION 12

OF THE ACQUIRED OR EMPIRIC KNOWLEDGE OF CHRIST'S SOUL (In Four Articles)

We must now consider the acquired or empiric knowledge of Christ's soul; and under this head there are four points of inquiry:

(1) Whether Christ knew all things by this knowledge?

(2) Whether He advanced in this knowledge?

(3) Whether He learned anything from man?

(4) Whether He received anything from angels? _____

FIRST ARTICLE [III, Q. 12, Art. 1]

Whether Christ Knew All Things by This Acquired or Empiric Knowledge?

Objection 1: It would seem that Christ did not know everything by this knowledge. For this knowledge is acquired by experience. But Christ did not experience everything. Therefore He did not know everything by this knowledge.

Obj. 2: Further, man acquires knowledge through the senses. But not all sensible things were subjected to Christ's bodily senses. Therefore Christ did not know everything by this knowledge.

Obj. 3: Further, the extent of knowledge depends on the things knowable. Therefore if Christ knew all things by this knowledge, His acquired knowledge would have been equal to His infused and beatific knowledge; which is not fitting. Therefore Christ did not know all things by this knowledge.

On the contrary, Nothing imperfect was in Christ's soul. Now this knowledge of His would have been imperfect if He had not known all things by it, since the imperfect is that to which addition may be made. Hence Christ knew all things by this knowledge.

I answer that, Acquired knowledge is held to be in Christ's soul, as we have said (Q. 9, A. 4), by reason of the active intellect, lest its action, which is to make things actually intelligible, should be wanting; even as imprinted or infused knowledge is held to be in Christ's soul for the perfection of the passive intellect. Now as the passive intellect is that by which "all things are in potentiality," so the active intellect is that by which "all are in act," as is said De Anima iii, 18. And hence, as the soul of Christ knew by infused knowledge all things to which the passive intellect is in any way in potentiality, so by acquired knowledge it knew whatever can be known by the action of the active intellect.

Reply Obj. 1: The knowledge of things may be acquired not merely by experiencing the things themselves, but by experiencing other things; since by virtue of the light of the active intellect man can go on to understand effects from causes, and causes from effects, like from like, contrary from contrary. Therefore Christ, though He did not experience all things, came to the knowledge of all things from what He did experience.
