But beyond all this [i.e., the first reason for the incarnation], there was a debt owing which must need be paid; for, as I said before, all men were due to die. Here, then, is the second reason why the Word dwelt among us, namely that having proved His Godhead by His works, He might offer the sacrifice on behalf of all, surrendering His own temple to death in place of all, to settle man’s account with death and free him from the primal transgression. In the same act also He showed Himself mightier than death, displaying His own body incorruptible as the first-fruits of the resurrection.

-Saint Athanasius, On the Incarnation
