Reply to Objection 3: The soul formally possesses the life-giving energy, and therefore, while it is present, and united formally, the body must necessarily be a living one, whereas the Godhead has not the life-giving energy formally, but effectively; because It cannot be the form of the body: and therefore it is not necessary for the flesh to be living while the union of the Godhead with the flesh remains, since God does not act of necessity, but of His own will.
Whether in Christ's death there was a severance between His Godhead and His soul?
Objection 1: It would seem that there was a severance in death between Christ's Godhead and His soul, because our Lord said ( Jn. 10:18 ): "No man taketh away My soul from Me: but I lay it down of Myself, and I have power to lay it down, and I have power to take it up again." But it does not appear that the body can set the soul aside, by separating the soul from itself, because the soul is not subject to the power of the body, but rather conversely: and so it appears that it belongs to Christ, as the Word of God, to lay down His soul: but this is to separate it from Himself. Consequently, by death His soul was severed from the Godhead.
Objection 2: Further, Athanasius [*Vigilius Tapsensis, De Trin. vi; Bardenhewer assigns it to St. Athanasius: 45, iii. The full title is De Trinitate et Spiritu Sancto] says that he "is accursed who does not confess that the entire man, whom the Son of God took to Himself, after being assumed once more or delivered by Him, rose again from the dead on the third day." But the entire man could not be assumed again, unless the entire man was at one time separated from the Word of God: and the entire man is made of soul and body. Therefore there was a separation made at one time of the Godhead from both the body and the soul.
Objection 3: Further, the Son of God is truly styled a man because of the union with the entire man. If then, when the union of the soul with the body was dissolved by death, the Word of God continued united with the soul, it would follow that the Son of God could be truly called a soul. But this is false, because since the soul is the form of the body, it would result in the Word of God being the form of the body; which is impossible. Therefore, in death the soul of Christ was separated from the Word of God.
Objection 4: Further, the separated soul and body are not one hypostasis, but two. Therefore, if the Word of God remained united with Christ's soul and body, then, when they were severed by Christ's death, it seems to follow that the Word of God was two hypostases during such time as Christ was dead; which cannot be admitted. Therefore after Christ's death His soul did not continue to be united with the Word.
On the contrary, Damascene says (De Fide Orth. iii): "Although Christ died as man, and His holy soul was separated from His spotless body, nevertheless His Godhead remained unseparated from both---from the soul, I mean, and from the body."
I answer that, The soul is united with the Word of God more immediately and more primarily than the body is, because it is through the soul that the body is united with the Word of God, as stated above (Q[6], A[1]). Since, then, the Word of God was not separated from the body at Christ's death, much less was He separated from the soul. Accordingly, since what regards the body severed from the soul is affirmed of the Son of God---namely, that "it was buried"---so is it said of Him in the Creed that "He descended into hell," because His soul when separated from the body did go down into hell.
Reply to Objection 1: Augustine (Tract. xlvii in Joan.), in commenting on the text of John, asks, since Christ is Word and soul and body, "whether He putteth down His soul, for that He is the Word? Or, for that He is a soul?" Or, again, "for that He is flesh?" And he says that, "should we say that the Word of God laid down His soul" . . . it would follow that "there was a time when that soul was severed from the Word"---which is untrue. "For death severed the body and soul . . . but that the soul was severed from the Word I do not affirm . . . But should we say that the soul laid itself down," it follows "that it is severed from itself: which is most absurd." It remains, therefore, that "the flesh itself layeth down its soul and taketh it again, not by its own power, but by the power of the Word dwelling in the flesh": because, as stated above (A[2]), the Godhead of the Word was not severed from the flesh in death.
Reply to Objection 2: In those words Athanasius never meant to say that the whole man was reassumed---that is, as to all his parts---as if the Word of God had laid aside the parts of human nature by His death; but that the totality of the assumed nature was restored once more in the resurrection by the resumed union of soul and body.
Reply to Objection 2: Through being united to human nature, the Word of God is not on that account called human nature: but He is called a man---that is, one having human nature. Now the soul and the body are essential parts of human nature. Hence it does not follow that the Word is a soul or a body through being united with both, but that He is one possessing a soul or a body.
Reply to Objection 4: As Damascene says (De Fide Orth. iii): "In Christ's death the soul was separated from the flesh: not one hypostasis divided into two: because both soul and body in the same respect had their existence from the beginning in the hypostasis of the Word; and in death, though severed from one another, each one continued to have the one same hypostasis of the Word. Wherefore the one hypostasis of the Word was the hypostasis of the Word, of the soul, and of the body. For neither soul nor body ever had an hypostasis of its own, besides the hypostasis of the Word: for there was always one hypostasis of the Word, and never two."
Whether Christ was a man during the three days of His death?
Objection 1: It would seem that Christ was a man during the three days of His death, because Augustine says (De Trin. iii): "Such was the assuming [of nature] as to make God to be man, and man to be God." But this assuming [of nature] did not cease at Christ's death. Therefore it seems that He did not cease to be a man in consequence of death.
Objection 2: Further, the Philosopher says (Ethic. ix) that "each man is his intellect"; consequently, when we address the soul of Peter after his death we say: "Saint Peter, pray for us." But the Son of God after death was not separated from His intellectual soul. Therefore, during those three days the Son of God was a man.
Objection 3: Further, every priest is a man. But during those three days of death Christ was a priest: otherwise what is said in Ps. 109:4 would not be true: "Thou art a priest for ever." Therefore Christ was a man during those three days.
On the contrary, When the higher [species] is removed, so is the lower. But the living or animated being is a higher species than animal and man, because an animal is a sensible animated substance. Now during those three days of death Christ's body was not living or animated. Therefore He was not a man.
I answer that, It is an article of faith that Christ was truly dead: hence it is an error against faith to assert anything whereby the truth of Christ's death is destroyed. Accordingly it is said in the Synodal epistle of Cyril [*Act. Conc. Ephes. P. I, cap. xxvi]: "If any man does not acknowledge that the Word of God suffered in the flesh, and was crucified in the flesh and tasted death in the flesh, let him be anathema." Now it belongs to the truth of the death of man or animal that by death the subject ceases to be man or animal; because the death of the man or animal results from the separation of the soul, which is the formal complement of the man or animal. Consequently, to say that Christ was a man during the three days of His death simply and without qualification, is erroneous. Yet it can be said that He was "a dead man" during those three days.
However, some writers have contended that Christ was a man during those three days, uttering words which are indeed erroneous, yet without intent of error in faith: as Hugh of Saint Victor, who (De Sacram. ii) contended that Christ, during the three days that followed His death, was a man, because he held that the soul is a man: but this is false, as was shown in the FP, Q[75], A[4]. Likewise the Master of the Sentences (iii, D, 22) held Christ to be a man during the three days of His death for quite another reason. For he believed the union of soul and flesh not to be essential to a man, and that for anything to be a man it suffices if it have a soul and body, whether united or separated: and that this is likewise false is clear both from what has been said in the FP, Q[75], A[4], and from what has been said above regarding the mode of union (Q[2] , A[5]).
Reply to Objection 1: The Word of God assumed a united soul and body: and the result of this assumption was that God is man, and man is God. But this assumption did not cease by the separation of the Word from the soul or from the flesh; yet the union of soul and flesh ceased.
Reply to Objection 2: Man is said to be his own intellect, not because the intellect is the entire man, but because the intellect is the chief part of man, in which man's whole disposition lies virtually; just as the ruler of the city may be called the whole city, since its entire disposal is vested in him.
Reply to Objection 3: That a man is competent to be a priest is by reason of the soul, which is the subject of the character of order: hence a man does not lose his priestly order by death, and much less does Christ, who is the fount of the entire priesthood.
Whether Christ's was identically the same body living and dead?
Objection 1: It would seem that Christ's was not identically the same body living and dead. For Christ truly died just as other men do. But the body of everyone else is not simply identically the same, dead and living, because there is an essential difference between them. Therefore neither is the body of Christ identically the same, dead and living.
Objection 2: Further, according to the Philosopher (Metaph. v, text. 12), things specifically diverse are also numerically diverse. But Christ's body, living and dead, was specifically diverse: because the eye or flesh of the dead is only called so equivocally, as is evident from the Philosopher (De Anima ii, text. 9; Metaph. vii). Therefore Christ's body was not simply identically the same, living and dead.
