We have seen, then, how grave an offence it is not to believe the resurrection; for if we rise not again, then Christ died in vain, then Christ rose not again. For if He rose not for us, He certainly rose not at all, for He had no need to rise for Himself. The universe rose again in Him, the heaven rose again in Him, the earth rose again in Him, for there shall be a new heaven and a new earth. But where was the necessity of a resurrection for Him Whom the claims of death held not? For though He died as man, yet was He free in hell itself.

Wilt thou know how free? “I am become as a man that hath no help, free among the dead.” And well is He called free, Who had power to raise Himself, according to that which is written: “Destroy this temple, and in three days I will raise it up.” And well is He called free, Who had descended to rescue others. For He was made as a man, not, indeed, in appearance only, but so fashioned in truth, for He is man, and who shall know Him? For, “being made in the likeness of men, and being found in fashion as a man, He humbled Himself, becoming obedient even unto death,” in order that through that obedience we might see His glory, “the glory as of the Only-begotten of the Father,” according to Saint John. For thus is the statement of Scripture preserved, if both the glory of the Only-begotten and the nature of perfect man are preserved in Christ.

And so He needed no helper. For He needed none when He made the world, so as to need none when He would redeem it. No legate, no messenger, but the Lord Himself made it whole. “He spake and it was done.” The Lord Himself made it whole, Himself in every part, because all things were by Him. For who should help Him in Whom all things were created and by Whom all things consist? Who should help Him Who makes all things in a moment, and raises the dead at the last trump? The “last,” not as though He could not raise them at the first, or the second, or the third, but an order is observed, not that a difficulty may be at last overcome, but that the prescribed number be accomplished. — Two Books on the Decease of His Brother Saytrus – Book II, para. 102-104.
