. In his treatise On the Incarnation, Athanasius wrote the following (italics mine):
Thus, taking a body like our own, because all our bodies were liable to the corruption of death, He surrendered His body to death in the place of all, and offered it to the Father. This He did out of sheer love for us, so that in His death all might die…. This He did that He might turn again to incorruption men who had turned back to corruption, and make them alive through death by the appropriation of His body and by the grace of His resurrection… (section 8).
What then was God to do? What else could He possibly do, being God, but renew His Image in mankind, so that through it men might once more come to know Him? And how could this be done, save by the coming of the very Image Himself, our Savior Jesus Christ?…
The Word of God came in His own Person, because it was He alone, the Image of the Father, Who could recreate man made after the Image. Thus it happened that two opposite marvels took place at once: the death of all was consummated in the Lord’s body; yet because the Word was in it, death and corruption were in the same act utterly abolished. Death there had to be, and death for all, so that the due of all might be paid (section 13).
Wherefore the Word…being Himself incapable of death, assumed a mortal body, that He might offer it as his own in the place of all, and suffering for the sake of all through His union with it, “might bring to nought him that had the power over death, that is, the devil, and might deliver them who all their lifetime were enslaved by the fear of death” (Hebrews 2:14-15) (section 20).
By his death salvation has come to all men, and all creation has been redeemed (section 37).
