Summa Th. III EN Qu.15 a.7
Objection: 1. It would seem that there was no fear in Christ. For it is written (Pr 28,1): "The just, bold as a lion, shall be without dread." But Christ was most just. Therefore there was no fear in Christ.
2. Further, Hilary says (De Trin. x): "I ask those who think thus, does it stand to reason that He should dread to die, Who by expelling all dread of death from the Apostles, encouraged them to the glory of martyrdom?" Therefore it is unreasonable that there should be fear in Christ.
3. Further, fear seems only to regard what a man cannot avoid. Now Christ could have avoided both the evil of punishment which He endured, and the evil of fault which befell others. Therefore there was no fear in Christ.
On the contrary It is written (Mc 4,33): Jesus "began to fear and to be heavy."
I answer that As sorrow is caused by the apprehension of a present evil, so also is fear caused by the apprehension of a future evil. Now the apprehension of a future evil, if the evil be quite certain, does not arouse fear. Hence the Philosopher says (Rhet. ii, 5) that we do not fear a thing unless there is some hope of avoiding it. For when there is no hope of avoiding it the evil is considered present, and thus it causes sorrow rather than fear. Hence fear may be considered in two ways. First, inasmuch as the sensitive appetite naturally shrinks from bodily hurt, by sorrow if it is present, and by fear if it is future; and thus fear was in Christ, even as sorrow. Secondly, fear may be considered in the uncertainty of the future event, as when at night we are frightened at a sound, not knowing what it is; and in this way there was no fear in Christ, as Damascene says (De Fide Orth. iii, 23).
Reply to Objection: 1. The just man is said to be "without dread," in so far as dread implies a perfect passion drawing man from what reason dictates. And thus fear was not in Christ, but only as a propassion. Hence it is said (Mc 14,33) that Jesus "began to fear and to be heavy," with a propassion, as Jerome expounds (Mt 26,37).
2. Hilary excludes fear from Christ in the same way that he excludes sorrow, i.e. as regards the necessity of fearing. And yet to show the reality of His human nature, He voluntarily assumed fear, even as sorrow.
3. Although Christ could have avoided future evils by the power of His Godhead, yet they were unavoidable, or not easily avoidable by the weakness of the flesh.
Objection: 1. It would seem that in Christ there was no wonder. For the Philosopher says (Metaph. i, 2) that wonder results when we see an effect without knowing its cause; and thus wonder belongs only to the ignorant. Now there was no ignorance in Christ, as was said Article [3]. Therefore there was no wonder in Christ.
2. Further, Damascene says (De Fide Orth. ii, 15) that "wonder is fear springing from the imagination of something great"; and hence the Philosopher says (Ethic. iv, 3) that the "magnanimous man does not wonder." But Christ was most magnanimous. Therefore there was no wonder in Christ.
3. Further, no man wonders at what he himself can do. Now Christ could do whatsoever was great. Therefore it seems that He wondered at nothing.
On the contrary It is written (Mt 8,10): "Jesus hearing this," i.e. the words of the centurion, "marveled."
I answer that Wonder properly regards what is new and unwonted. Now there could be nothing new and unwonted as regards Christ's Divine knowledge, whereby He saw things in the Word; nor as regards the human knowledge, whereby He saw things by infused species. Yet things could be new and unwonted with regard to His empiric knowledge, in regard to which new things could occur to Him day by day. Hence, if we speak of Christ with respect to His Divine knowledge, and His beatific and even His infused knowledge, there was no wonder in Christ. But if we speak of Him with respect to empiric knowledge, wonder could be in Him; and He assumed this affection for our instruction, i.e. in order to teach us to wonder at what He Himself wondered at. Hence Augustine says (Super Gen. Cont. Manich. i, 8): "Our Lord wondered in order to show us that we, who still need to be so affected, must wonder. Hence all these emotions are not signs of a disturbed mind, but of a master teaching."
Reply to Objection: 1. Although Christ was ignorant of nothing, yet new things might occur to His empiric knowledge, and thus wonder would be caused.
2. Christ did not marvel at the Centurion's faith as if it was great with respect to Himself, but because it was great with respect to others.
3. He could do all things by the Divine power, for with respect to this there was no wonder in Him, but only with respect to His human empiric knowledge, as was said above.
Objection: 1. It would seem that there was no anger in Christ. For it is written (Jc 1,20): "The anger of man worketh not the justice of God." Now whatever was in Christ pertained to the justice of God, since of Him it is written (1Co 1,30): "For He [Vulg.: 'Who'] of God is made unto us . . . justice." Therefore it seems that there was no anger in Christ.
2. Further, anger is opposed to meekness, as is plain from Ethic. iv, 5. But Christ was most meek. Therefore there was no anger in Him.
3. Further, Gregory says (Moral. v, 45) that "anger that comes of evil blinds the eye of the mind, but anger that comes of zeal disturbs it." Now the mind's eye in Christ was neither blinded nor disturbed. Therefore in Christ there was neither sinful anger nor zealous anger.
On the contrary It is written (Jn 2,17) that the words of Ps 58,10, "the zeal of Thy house hath eaten me up," were fulfilled in Him.
I answer that As was said in the FS, Question [46], Article [3], ad 3, and SS, Question [158], Article [2], ad 3, anger is an effect of sorrow. or when sorrow is inflicted upon someone, there arises within him a desire of the sensitive appetite to repel this injury brought upon himself or others. Hence anger is a passion composed of sorrow and the desire of revenge. Now it was said (Article [6]) that sorrow could be in Christ. As to the desire of revenge it is sometimes with sin, i.e. when anyone seeks revenge beyond the order of reason: and in this way anger could not be in Christ, for this kind of anger is sinful. Sometimes, however, this desire is without sin---nay, is praiseworthy, e.g. when anyone seeks revenge according to justice, and this is zealous anger. For Augustine says (on Jn 2,17) that "he is eaten up by zeal for the house of God, who seeks to better whatever He sees to be evil in it, and if he cannot right it, bears with it and sighs." Such was the anger that was in Christ.
Reply to Objection: 1. As Gregory says (Moral. v), anger is in man in two ways---sometimes it forestalls reason, and causes it to operate, and in this way it is properly said to work, for operations are attributed to the principal agent. It is in this way that we must understand that "the anger of man worketh not the justice of God." Sometimes anger follows reason, and is, as it were, its instrument, and then the operation, which pertains to justice, is not attributed to anger but to reason.
2. It is the anger which outsteps the bounds of reason that is opposed to meekness, and not the anger which is controlled and brought within its proper bounds by reason, for meekness holds the mean in anger.
3. In us the natural order is that the soul's powers mutually impede each other, i.e. if the operation of one power is intense, the operation of the other is weakened. This is the reason why any movement whatsoever of anger, even if it be tempered by reason, dims the mind's eye of him who contemplates. But in Christ, by control of the Divine power, "every faculty was allowed to do what was proper to it," and one power was not impeded by another. Hence, as the joy of His mind in contemplation did not impede the sorrow or pain of the inferior part, so, conversely, the passions of the inferior part no-wise impeded the act of reason.
Objection: 1. It would seem that Christ was not at once a wayfarer and a comprehensor. For it belongs to a wayfarer to be moving toward the end of beatitude, and to a comprehensor it belongs to be resting in the end. Now to be moving towards the end and to be resting in the end cannot belong to the same. Therefore Christ could not be at once wayfarer and comprehensor.
2. Further, to tend to beatitude, or to obtain it, does not pertain to man's body, but to his soul; hence Augustine says (Ep ad Dios. cxviii) that "upon the inferior nature, which is the body, there overflows, not indeed the beatitude which belongs to such as enjoy and understand, the fulness of health, i.e. the vigor of incorruption." Now although Christ had a passible body, He fully enjoyed God in His mind. Therefore Christ was not a wayfarer but a comprehensor.
3. Further, the Saints, whose souls are in heaven and whose bodies are in the tomb, enjoy beatitude in their souls, although their bodies are subject to death, yet they are called not wayfarers, but only comprehensors. Hence, with equal reason, would it seem that Christ was a pure comprehensor and nowise a wayfarer, since His mind enjoyed God although His body was mortal.
On the contrary It is written (Jr 14,8): "Why wilt Thou be as a stranger in the land, and as a wayfaring man turning in to lodge?"
I answer that A man is called a wayfarer from tending to beatitude, and a comprehensor from having already obtained beatitude, according to 1Co 9,24: "So run that you may comprehend [Douay: 'obtain']"; and Ph 3,12: "I follow after, if by any means I may comprehend [Douay: 'obtain']". Now man's perfect beatitude consists in both soul and body, as stated in the FS, Question [4], Article [6]. In the soul, as regards what is proper to it, inasmuch as the mind sees and enjoys God; in the body, inasmuch as the body "will rise spiritual in power and glory and incorruption," as is written 1Co 15,42. Now before His passion Christ's mind saw God fully, and thus He had beatitude as far as it regards what is proper to the soul; but beatitude was wanting with regard to all else, since His soul was passible, and His body both passible and mortal, as is clear from the above (Article [4]; Question [14], Articles [1],2). Hence He was at once comprehensor, inasmuch as He had the beatitude proper to the soul, and at the same time wayfarer, inasmuch as He was tending to beatitude, as regards what was wanting to His beatitude.
Reply to Objection: 1. It is impossible to be moving towards the end and resting in the end, in the same respect; but there is nothing against this under a different respect---as when a man is at once acquainted with what he already knows, and yet is a learner with regard to what he does not know.
2. Beatitude principally and properly belongs to the soul with regard to the mind, yet secondarily and, so to say, instrumentally, bodily goods are required for beatitude; thus the Philosopher says (Ethic. i, 8), that exterior goods minister "organically" to beatitude.
3. There is no parity between the soul of a saint and of Christ, for two reasons: first, because the souls of saints are not passible, as Christ's soul was; secondly, because their bodies do nothing by which they tend to beatitude, as Christ by His bodily sufferings tended to beatitude as regards the glory of His body.
We must now consider the consequences of the union; and first as to what belongs to Christ in Himself; secondly, as to what belongs to Christ in relation with His Father; thirdly, as to what belongs to Christ in relation to us.
Concerning the first, there occurs a double consideration. The first is about such things as belong to Christ in being and becoming; the second regards such things as belong to Christ by reason of unity.
Under the first head there are twelve points of inquiry:
(1) Whether this is true: "God is man"?
(2) Whether this is true: "Man is God"?
(3) Whether Christ may be called a lordly man?
(4) Whether what belongs to the Son of Man may be predicated of the Son of God, and conversely?
(5) Whether what belongs to the Son of Man may be predicated of the Divine Nature, and what belongs to the Son of God of the human nature?
(6) Whether this is true: "The Son of God was made man"?
(7) Whether this is true: "Man became God"?
(8) Whether this is true: "Christ is a creature"?
(9) Whether this is true: "This man," pointing out Christ, "began to be"? or "always was"?
(10) Whether this is true: "Christ as man is a creature"?
(11) Whether this is true: "Christ as man is God"?
(12) Whether this is true: "Christ as man is a hypostasis or person"?
Objection: 1. It would seem that this is false: "God is man." For every affirmative proposition of remote matter is false. Now this proposition, "God is man," is on remote matter, since the forms signified by the subject and predicate are most widely apart. Therefore, since the aforesaid proposition is affirmative, it would seem to be false.
2. Further, the three Divine Persons are in greater mutual agreement than the human nature and the Divine. But in the mystery of the Incarnation one Person is not predicated of another; for we do not say that the Father is the Son, or conversely. Therefore it seems that the human nature ought not to be predicated of God by saying that God is man.
3. Further, Athanasius says (Symb. Fid.) that, "as the soul and the flesh are one man, so are God and man one Christ." But this is false: "The soul is the body." Therefore this also is false: "God is man."
4. Further, it was said in the FP, Question [39], Article [4] that what is predicated of God not relatively but absolutely, belongs to the whole Trinity and to each of the Persons. But this word "man" is not relative, but absolute. Hence, if it is predicated of God, it would follow that the whole Trinity and each of the Persons is man; and this is clearly false.
On the contrary It is written (Ph 2,6-7): "Who being in the form of God . . . emptied Himself, taking the form of a servant, being made in the likeness of man, and in habit found as a man"; and thus He Who is in the form of God is man. Now He Who is in the form of God is God. Therefore God is man.
I answer that This proposition "God is man," is admitted by all Christians, yet not in the same way by all. For some admit the proposition, but not in the proper acceptation of the terms. Thus the Manicheans say the Word of God is man, not indeed true, but fictitious man, inasmuch as they say that the Son of God assumed an imaginary body, and thus God is called man as a bronze figure is called man if it has the figure of a man. So, too, those who held that Christ's body and soul were not united, could not say that God is true man, but that He is figuratively called man by reason of the parts. Now both these opinions were disproved above (Question [2], Article [5]; Question [5], Article [1]).Some, on the contrary, hold the reality on the part of man, but deny the reality on the part of God. For they say that Christ, Who is God and man, is God not naturally, but by participation, i.e. by grace; even as all other holy men are called gods---Christ being more excellently so than the rest, on account of His more abundant grace. And thus, when it is said that "God is man," God does not stand for the true and natural God. And this is the heresy of Photinus, which was disproved above (Question [2], Articles [10],11). But some admit this proposition, together with the reality of both terms, holding that Christ is true God and true man; yet they do not preserve the truth of the predication. For they say that man is predicated of God by reason of a certain conjunction either of dignity, or of authority, or of affection or indwelling. It was thus that Nestorius held God to be man---nothing further being meant than that God is joined to man by such a conjunction that man is dwelt in by God, and united to Him in affection, and in a share of the Divine authority and honor. And into the same error fall those who suppose two supposita or hypostases in Christ, since it is impossible to understand how, of two things distinct in suppositum or hypostasis, one can be properly predicated of the other: unless merely by a figurative expression, inasmuch as they are united in something, as if we were to say that Peter is John because they are somehow mutually joined together. And these opinions also were disproved above (Question [2], Articles [3],6).Hence, supposing the truth of the Catholic belief, that the true Divine Nature is united with true human nature not only in person, but also in suppositum or hypostasis; we say that this proposition is true and proper, "God is man"---not only by the truth of its terms, i.e. because Christ is true God and true man, but by the truth of the predication. For a word signifying the common nature in the concrete may stand for all contained in the common nature, as this word "man" may stand for any individual man. And thus this word "God," from its very mode of signification, may stand for the Person of the Son of God, as was said in the FP, Question [39], Article [4]. Now of every suppositum of any nature we may truly and properly predicate a word signifying that nature in the concrete, as "man" may properly and truly be predicated of Socrates and Plato. Hence, since the Person of the Son of God for Whom this word "God" stands, is a suppositum of human nature this word man may be truly and properly predicated of this word "God," as it stands for the Person of the Son of God.
Reply to Objection: 1. When different forms cannot come together in one suppositum, the proposition is necessarily in remote matter, the subject signifying one form and the predicate another. But when two forms can come together in one suppositum, the matter is not remote, but natural or contingent, as when I say: "Something white is musical." Now the Divine and human natures, although most widely apart, nevertheless come together by the mystery of the Incarnation in one suppositum, in which neither exists accidentally, but [both] essentially. Hence this proposition is neither in remote nor in contingent, but in natural matter; and man is not predicated of God accidentally, but essentially, as being predicated of its hypostasis---not, indeed, by reason of the form signified by this word "God," but by reason of the suppositum, which is a hypostasis of human nature.
2. The three Divine Persons agree in one Nature, and are distinguished in suppositum; and hence they are not predicated one of another. But in the mystery of the Incarnation the natures, being distinct, are not predicated one of the other, in the abstract. For the Divine Nature is not the human nature. But because they agree in suppositum, they are predicated of each other in the concrete.
3. "Soul" and "flesh" are taken in the abstract, even as Godhead and manhood; but in the concrete we say "animate" and "carnal" or "corporeal," as, on the other hand, "God" and "man." Hence in both cases the abstract is not predicated of the abstract, but only the concrete of the concrete.
4. This word "man" is predicated of God, because of the union in person, and this union implies a relation. Hence it does not follow the rule of those words which are absolutely predicated of God from eternity.
Objection: 1. It would seem that this is false: "Man is God." For God is an incommunicable name; hence (Sg 13,10 Sg 14,21) idolaters are rebuked for giving the name of God, which is incommunicable, to wood and stones. Hence with equal reason does it seem unbecoming that this word "God" should be predicated of man.
2. Further, whatever is predicated of the predicate may be predicated of the subject. But this is true: "God is the Father," or "God is the Trinity." Therefore, if it is true that "Man is God," it seems that this also is true: "Man is the Father," or "Man is the Trinity." But these are false. Therefore the first is false.
3. Further, it is written (Ps 80,10): "There shall be no new God in thee." But man is something new; for Christ was not always man. Therefore this is false: "Man is God."
On the contrary It is written (Rm 9,5): "Of whom is Christ according to the flesh, Who is over all things, God blessed for ever." Now Christ, according to the flesh, is man. Therefore this is true: "Man is God."
I answer that Granted the reality of both natures, i.e. Divine and human, and of the union in person and hypostasis, this is true and proper: "Man is God," even as this: "God is man." For this word "man" may stand for any hypostasis of human nature; and thus it may stand for the Person of the Son of God, Whom we say is a hypostasis of human nature. Now it is manifest that the word "God" is truly and properly predicated of the Person of the Son of God, as was said in the FP, Question [39], Article [4]. Hence it remains that this is true and proper: "Man is God."
Reply to Objection: 1. Idolaters attributed the name of the Deity to stones and wood, considered in their own nature, because they thought there was something divine in them. But we do not attribute the name of the Deity to the man in His human nature, but in the eternal suppositum, which by union is a suppositum of human nature, as stated above.
2. This word "Father" is predicated of this word "God," inasmuch as this word "God" stands for the Person of the Father. And in this way it is not predicated of the Person of the Son, because the Person of the Son is not the Person of the Father. And, consequently, it is not necessary that this word "Father" be predicated of this word "Man," of which the Word "God" is predicated, inasmuch as "Man" stands for the Person of the Son.
3. Although the human nature in Christ is something new, yet the suppositum of the human nature is not new, but eternal. And because this word "God" is predicated of man not on account of the human nature, but by reason of the suppositum, it does not follow that we assert a new God. But this would follow, if we held that "Man" stands for a created suppositum: even as must be said by those who assert that there are two supposita in Christ [*Cf. Question [2], Articles [3],6].
[*The question is hardly apposite in English. St. Thomas explains why we can say in Latin, e.g. 'oratio dominica' (the Lord's Prayer) or 'passio dominica' (Our Lord's Passion), but not speak of our Lord as 'homo dominicus' (a lordly man)].
Objection: 1. It would seem that Christ can be called a lordly man. For Augustine says (Qq. lxxxiii, qu. 36) that "we are to be counseled to hope for the goods that were in the Lordly Man"; and he is speaking of Christ. Therefore it seems that Christ was a lordly man.
2. Further, as lordship belongs to Christ by reason of His Divine Nature, so does manhood belong to the human nature. Now God is said to be "humanized," as is plain from Damascene (De Fide Orth. iii, 11), where he says that "being humanized manifests the conjunction with man." Hence with like reason may it be said denominatively that this man is lordly.
3. Further, as "lordly" is derived from "lord," so is Divine derived from "Deus" [God]. But Dionysius (Eccl. Hier. iv) calls Christ the "most Divine Jesus." Therefore with like reason may Christ be called a lordly man.
On the contrary Augustine says (Retract. i, 19): "I do not see that we may rightly call Jesus Christ a lordly man, since He is the Lord Himself."
I answer that As was said above (Article [2], ad 3), when we say "the Man Christ Jesus," we signify the eternal suppositum, which is the Person of the Son of God, because there is only one suppositum of both natures. Now "God" and "Lord" are predicated essentially of the Son of God; and hence they ought not to be predicated denominatively, since this is derogatory to the truth of the union. Hence, since we say "lordly" denominatively from lord, it cannot truly and properly be said that this Man is lordly, but rather that He is Lord. But if, when we say "the Man Christ Jesus," we mean a created suppositum, as those who assert two supposita in Christ, this man might be called lordly, inasmuch as he is assumed to a participation of Divine honor, as the Nestorians said. And, even in this way, the human nature is not called "divine" by essence, but "deified"---not, indeed, by its being converted into the Divine Nature, but by its conjunction with the Divine Nature in one hypostasis, as is plain from Damascene (De Fide Orth. iii, 11,17).
Reply to Objection: 1. Augustine retracts these and the like words (Retract. i, 19); hence, after the foregoing words (Retract. i, 19), he adds: "Wherever I have said this," viz. that Christ Jesus is a lordly man, "I wish it unsaid, having afterwards seen that it ought not to be said although it may be defended with some reason," i.e. because one might say that He was called a lordly man by reason of the human nature, which this word "man" signifies, and not by reason of the suppositum.
2. This one suppositum, which is of the human and Divine natures, was first of the Divine Nature, i.e. from eternity. Afterwards in time it was made a suppositum of human nature by the Incarnation. And for this reason it is said to be "humanized"---not that it assumed a man, but that it assumed human nature. But the converse of this is not true, viz. that a suppositum of human nature assumed the Divine Nature; hence we may not say a "deified" or "lordly" man.
3. This word Divine is wont to be predicated even of things of which the word God is predicated essentially; thus we say that "the Divine Essence is God," by reason of identity; and that "the Essence belongs to God," or is "Divine," on account of the different way of signifying; and we speak of the "Divine Word," though the Word is God. So, too, we say "a Divine Person," just as we say "the person of Plato," on account of its different mode of signification. But "lordly" is not predicated of those of which "lord" is predicated; for we are not wont to call a man who is a lord, lordly; but whatsoever belongs to a lord is called lordly, as the "lordly will," or the "lordly hand," or the "lordly possession." And hence the man Christ, Who is our Lord, cannot be called lordly; yet His flesh can be called "lordly flesh" and His passion the "lordly passion."
Objection: 1. It would seem that what belongs to the human nature cannot be said of God. For contrary things cannot be said of the same. Now, what belongs to human nature is contrary to what is proper to God, since God is uncreated, immutable, and eternal, and it belongs to the human nature to be created temporal and mutable. Therefore what belongs to the human nature cannot be said of God.
2. Further, to attribute to God what is defective seems to be derogatory to the Divine honor, and to be a blasphemy. Now what pertains to the human nature contains a kind of defect, as to suffer, to die, and the like. Hence it seems that what pertains to the human nature can nowise be said of God.
3. Further, to be assumed pertains to the human nature; yet it does not pertain to God. Therefore what belongs to the human nature cannot be said of God.
On the contrary Damascene says (De Fide Orth. iii, 4) that "God assumed the idioms," i.e. the properties, "of flesh, since God is said to be passible, and the God of glory was crucified."
I answer that On this question there was a difference of opinion between Nestorians and Catholics. The Nestorians wished to divide words predicated of Christ, in this way, viz. that such as pertained to human nature should not be predicated of God, and that such as pertained to the Divine Nature should not be predicated of the Man. Hence Nestorius said: "If anyone attempt to attribute sufferings to the Word, let him be anathema" [*Council of Ephesus, Part I, ch. 29]. But if there are any words applicable to both natures, of them they predicated what pertained to both natures, as "Christ" or "Lord." Hence they granted that Christ was born of a Virgin, and that He was from eternity; but they did not say that God was born of a virgin, or that the Man was from eternity. Catholics on the other hand maintained that words which are said of Christ either in His Divine or in His human nature may be said either of God or of man. Hence Cyril says [*Council of Ephesus, Part I, ch. 26]: "If anyone ascribes to two persons or substances," i.e. hypostases, "such words as are in the evangelical and apostolic Scriptures, or have been said of Christ by the Saints, or by Himself of Himself, and believes that some are to be applied to the Man, and apportions some to the Word alone---let him be anathema." And the reason of this is that, since there is one hypostasis of both natures, the same hypostasis is signified by the name of either nature. Thus whether we say "man" or "God," the hypostasis of Divine and human nature is signified. And hence, of the Man may be said what belongs to the Divine Nature, as of a hypostasis of the Divine Nature; and of God may be said what belongs to the human nature, as of a hypostasis of human nature.Nevertheless, it must be borne in mind that in a proposition in which something is predicated of another, we must not merely consider what the predicate is predicated of, but also the reason of its being predicated. Thus, although we do not distinguish things predicated of Christ, yet we distinguish that by reason of which they are predicated, since those things that belong to the Divine Nature are predicated of Christ in His Divine Nature, and those that belong to the human nature are predicated of Christ in His human nature. Hence Augustine says (De Trin. i, 11): "We must distinguish what is said by Scripture in reference to the form of God, wherein He is equal to the Father, and what in reference to the form of a servant, wherein He is less than the Father": and further on he says (De Trin. i, 13): "The prudent, careful, and devout reader will discern the reason and point of view of what is said."
Reply to Objection: 1. It is impossible for contraries to be predicated of the same in the same respects, but nothing prevents their being predicated of the same in different aspects. And thus contraries are predicated of Christ, not in the same, but in different natures.
2. If the things pertaining to defect were attributed to God in His Divine Nature, it would be a blasphemy, since it would be derogatory to His honor. But there is no kind of wrong done to God if they are attributed to Him in His assumed nature. Hence in a discourse of the Council of Ephesus [*Part III, ch. 10] it is said: "God accounts nothing a wrong which is the occasion of man's salvation. For no lowliness that He assumed for us injures that Nature which can be subject to no injury, yet makes lower things Its own, to save our nature. Therefore, since these lowly and worthless things do no harm to the Divine Nature, but bring about our salvation, how dost thou maintain that what was the cause of our salvation was the occasion of harm to God?"
3. To be assumed pertains to human nature, not in its suppositum, but in itself; and thus it does not belong to God.
Objection: 1. It would seem that what belongs to the human nature can be said of the Divine Nature. For what belongs to the human nature is predicated of the Son of God, and of God. But God is His own Nature. Therefore, what belongs to the human nature may be predicated of the Divine Nature.
2. Further, the flesh pertains to human nature. But as Damascene says (De Fide Orth. iii, 6), "we say, after the blessed Athanasius and Cyril, that the Nature of the Word was incarnate." Therefore it would seem with equal reason that what belongs to the human nature may be said of the Divine Nature.
3. Further, what belongs to the Divine Nature belongs to Christ's human nature; such as to know future things and to possess saving power. Therefore it would seem with equal reason that what belongs to the human may be said of the Divine Nature.
On the contrary Damascene says (De Fide Orth. iii, 4): "When we mention the Godhead we do not predicate of it the idioms," i.e. the properties, "of the humanity; for we do not say that the Godhead is passible or creatable." Now the Godhead is the Divine Nature. Therefore what is proper to the human nature cannot be said of the Divine Nature.
I answer that What belongs to one cannot be said of another, unless they are both the same; thus "risible" can be predicated only of man. Now in the mystery of the Incarnation the Divine and human natures are not the same; but the hypostasis of the two natures is the same. And hence what belongs to one nature cannot be predicated of the other if they are taken in the abstract. Now concrete words stand for the hypostasis of the nature; and hence of concrete words we may predicate indifferently what belongs to either nature---whether the word of which they are predicated refers to one nature, as the word "Christ," by which is signified "both the Godhead anointing and the manhood anointed"; or to the Divine Nature alone, as this word "God" or "the Son of God"; or to the manhood alone, as this word "Man" or "Jesus." Hence Pope Leo says (Ep ad Palaest. cxxiv): "It is of no consequence from what substance we name Christ; because since the unity of person remains inseparably, one and the same is altogether Son of Man by His flesh, and altogether Son of God by the Godhead which He has with the Father."
Reply to Objection: 1. In God, Person and Nature are really the same; and by reason of this identity the Divine Nature is predicated of the Son of God. Nevertheless, its mode of predication is different; and hence certain things are said of the Son of God which are not said of the Divine Nature; thus we say that the Son of God is born, yet we do not say that the Divine Nature is born; as was said in the FP, Question [39], Article [5]. So, too, in the mystery of the Incarnation we say that the Son of God suffered, yet we do not say that the Divine Nature suffered.
2. Incarnation implies union with flesh, rather than any property of flesh. Now in Christ each nature is united to the other in person; and by reason of this union the Divine Nature is said to be incarnate and the human nature deified, as stated above (Question [2], Article [1], ad 3).
3. What belongs to the Divine Nature is predicated of the human nature---not, indeed, as it belongs essentially to the Divine Nature, but as it is participated by the human nature. Hence, whatever cannot be participated by the human nature (as to be uncreated and omnipotent), is nowise predicated of the human nature. But the Divine Nature received nothing by participation from the human nature; and hence what belongs to the human nature can nowise be predicated of the Divine Nature.
