St. Athanasius

He, the Life of all, our Lord and Saviour, did not arrange the manner of his own death lest He should seem to be afraid of some other kind. No. He accepted and bore upon the cross a death inflicted by others, and those other His special enemies, a death which to them was supremely terrible and by no means to be faced; and He did this in order that, by destroying even this death, He might Himself be believed to be the Life, and the power of death be recognised as finally annulled. A marvellous and mighty paradox has thus occurred, for the death which they thought to inflict on Him as dishonour and disgrace has become the glorious monument to death's defeat.

— St. Athanasius

The body of the Word, then, being a real human body, in spite of its having been uniquely formed from a virgin, was of itself mortal and, like other bodies, liable to death. But the indwelling of the Word loosed it from this natural liability, so that corruption could not touch it. Thus is 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.
