Reply Obj. 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 Obj. 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 Obj. 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." _______________________
FOURTH ARTICLE [III, Q. 50, Art. 4]
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.
Obj. 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.
Obj. 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.
