This leaves freedom to understand them without being constrained by the flow of the argument. St. Chrysostom himself says of them, "Why has the Apostle turned aside here from the resurrection?" Though he immediately says that he has not turned aside, he still understands them independently of the flow of the discourse. This is noted because throughout this section it is difficult to establish exactness in the ideas and their connection. By the word "sown," the burial in the earth of dead bodies is indicated, according to St. Chrysostom. Yet the comparison takes present bodies generally, as they appear on earth, not only as they are found in the tomb and grave. Still, in the grave it is most evident what they are. We must think this because among the features of the bodies sown stands the fact that they are natural, though the soul is already absent from them. Also, the fact that they are in weakness is not fully applicable to bodies being lowered into the grave. The opposing features of present and future bodies are clear in themselves. It is sown in corruption, that is, in order to dissolve into the elements of which it is composed. "In two or three days it undergoes foul-smelling corruption" (Theodoret). But in its very essence it is also corruptible. It is formed and sustained through the dissolution of consumed foods, and then through their forced union within, by the action of the vital power, not by simple chemical affinity. Therefore it is already destined, as soon as this life-giving principle departs from it, to fall apart and be dissolved by the action of the chemical process that rules outside it. Until then, it had existed in defiance of that process. It rises in incorruption. It will rise in such a way that it can no longer be considered condemned to dissolution. It will be formed and sustained not through the dissolution and union of coarse substances taken within. Therefore it itself will be free from dissolution. The Apostle previously said that God will abolish the belly. Life will then be sustained by another manner, and the body's formation and composition will be of another kind. The vital power, which now labors to build and sustain the body by struggling with coarse matter, will then be in direct communion with the very source of the power that gives life to all. From it, the body will drink life, or whatever is needed for life.
