29 The true confession of the resurrection declares that the flesh will be glorious, but without destroying its reality. And when the Apostle says, “This is corruptible and mortal,” his words denote this very body, that is to say, the flesh which was then seen. But when he adds that it puts on incorruption and immortality, he does not say that that which is put on, that is the clothing, does away with the body which it adorns in glory, but that it makes that body glorious, which before lacked glory; so that the more worthless robe of mortality and weakness being laid aside, we may be clothed with the gold of immortality, and, so to speak, with the blessedness of strength as well as virtue; since we wish not to be stripped of the flesh, but to put on over it the vesture of glory, and desire to be clothed upon with our house, which is from heaven, that mortality may be swallowed up by life.
Certainly, no one is clothed upon who was not previously clothed. Accordingly, our Lord was not so transfigured on the mountain that He lost His hands and feet and other members, and suddenly began to roll along in a round shape like that of the sun or a ball; but the same members glowed with the brightness of the sun and blinded the eyes of the Apostles. Hence, also, His garments were changed, but so as to become white and glistening, not aërial, for I suppose you do not intend to maintain that His clothes also were spiritual. The Evangelist adds that His face shone like the sun; but when mention is made of His face, I reckon that His other members were beheld as well.
Enoch was translated in the flesh; Elias was carried up to heaven in the flesh. They are not dead, they are inhabitants of Paradise, and even there retain the members with which they were rapt away and translated. What we aim at in fasting, they have through fellowship with God. They feed on heavenly bread, and are satisfied with every word of God, having Him as their food who is also their Lord. Listen to the Saviour saying: “And my flesh rests in hope.” And elsewhere, “His flesh saw not corruption.”
And again, “All flesh shall see the salvation of God.” And must you be for ever making the body a twofold thing? Rather quote the vision of Ezekiel, who joins bones to bones and brings them forth from their sepulchres, and then, making them to stand on their feet, binds them together with flesh and sinews, and clothes them with skin.
