Acts 10:40

"Him God raised up the third day, and showed Him openly; not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with Him after He rose from the dead." This is a proof of the Resurrection. "And gave Him," it is added, "to be made manifest not to all the people, but to witnesses before ordained of God, even unto us:" and yet it was Christ Himself that elected them; but this also he refers to God. "To the before-ordained," he says, "even to us, who did eat and drink with Him after that He was risen from the dead." See whence he fetches his assurance of the resurrection. What is the reason that being risen he did no sign, but only ate and drank? Because the Resurrection itself was a great sign, and of this nothing was so much a sign as the eating and drinking.

Therefore, since it was necessary that the good Shepherd lay down his life on behalf of the sheep, so that through his own death he might destroy death, the captain of our salvation, by bringing death to pass, becomes a composite in his human nature, both as a priest and a lamb in the ability to receive a share of suffering. For since death is nothing but the dissolution of both soul and body, the one who united himself to both, I mean to both soul and to body, is separated from neither—"incapable of repentance," as the apostle says, "are the graces of God." So having distributed himself to both body and soul, on the one hand he opens paradise to the thief through his soul, and through his body he establishes the work of destruction. Now this is death's obliteration, that the destruction annihilated in the life-giving nature is made impotent, and this, which happens in regard to these [body and soul] becomes a shared benefit and grace of our nature. In this way, he who is in both, through his resurrection fits together all that was separate, he who, according to his power, gives his body to the heart of the earth, as it has been written, while he puts his soul away from himself, saying, on the one hand, to his father, "Into your hands I hand over my spirit," and on the other, to the thief, "Today you will be with me in paradise." … So in this way he comes both to be in death and not to be mastered by death.… The proof … is the operation that worked incorruption with regard to the body and a passing over into paradise with regard to the soul.… He demonstrates this who says that "God raised him from the dead." For not as Lazarus or anyone else of those who have returned to life by the power of another is he brought back to life—so clear is it how the resurrection of the Lord is to be conceived. Rather the Only Begotten himself raises up the person who was mixed together with himself, having both separated the soul from the body and having reunited both, and in this way a common salvation of human nature is effected.
