St. Justin Martyr: The Dignity of the Body
But following our order, we must now speak with respect to those who think meanly of the flesh, and say that it is not worthy of the resurrection nor of the heavenly economy, because, first, its substance is earth; and besides, because it is full of all wickedness, so that it forces the soul to sin along with it. But these persons seem to be ignorant of the whole work of God, both of the genesis and formation of man at the first, and why the things in the world were made. For does not the word say, "Let Us make man in our image, and after our likeness?" What kind of man? Manifestly He means fleshly man, For the word says, "And God took dust of the earth, and made man." It is evident, therefore, that man made in the image of God was of flesh. Is it not, then, absurd to say, that the flesh made by God in His own image is contemptible, and worth nothing? But that the flesh is with God a precious possession is manifest, first from its being formed by Him, if at least the image is valuable to the former and artist; and besides, its value can be gathered from the creation of the rest of the world. For that on account of which the rest is made, is the most precious of all to the maker.
Quite true, say they; yet the flesh is a sinner, so much so, that it forces the soul to sin along with it. And thus they vainly accuse it, and lay to its charge alone the sins of both. But in what instance can the flesh possibly sin by itself, if it have not the soul going before it and inciting it? For as in the case of a yoke of oxen, if one or other is loosed from the yoke, neither of them can plough alone; so neither can soul or body alone effect anything, if they be unyoked from their communion. And if it is the flesh that is the sinner, then on its account alone did the Saviour come, as He says, "I am not come to call the righteous, but sinners to repentance." Since, then, the flesh has been proved to be valuable in the sight of God, and glorious above all His works, it would very justly be saved by Him.
