corruption, it will arise in incorruption: it is sown in weakness, it will arise in power: it is sown in dishonour, it will arise in glory.”[763] As, therefore, there is a kind of advance in man, so that from being first an animal being, and not understanding what belongs to the Spirit of God, he reaches by means of instruction the stage of being made a spiritual being, and of judging all things, while he himself is judged by no one; so also, with respect to the state of the body, we are to hold that this very body which now, on account of its service to the soul, is styled an animal body, will, by means of a certain progress, when the soul, united to God, shall have been made one spirit with Him (the body even then ministering, as it were, to the spirit), attain to a spiritual condition and quality, especially since, as we have often pointed out, bodily nature was so formed by the Creator, as to pass easily into whatever condition He should wish, or the nature of the case demand. 7. The whole of this reasoning, then, amounts to this: that God created two general natures,—a visible, _i.e._ a corporeal nature; and an invisible nature, which is incorporeal. Now these two natures admit of two different permutations. That invisible and rational nature changes in mind and purpose, because it is endowed with freedom of will, and is on this account found sometimes to be engaged in the practice of good, and sometimes in that of the opposite. But this corporeal nature admits of a change in substance; whence also God, the arranger of all things, has the service of this matter at His command in the moulding, or fabrication, or re-touching of whatever He wishes, so that corporeal nature may be transmuted, and transformed into any forms or species whatever, according as the deserts of things may demand; which the prophet evidently has in view when he says, “It is God who makes and transforms all things.”[764]
