Concerning the Nature of Good, Against the Manichæans 10
10 Natures Corruptible, Because Made of Nothing PL 42, 554
All corruptible natures therefore are natures at all only so far as they are from God, nor would they be corruptible if they were of Him; because they would be what He himself is. Therefore of whatever measure, of whatever form, of whatever order, they are, they are so because it is God by whom they were made; but they are not immutable, because it is nothing of which they were made. For it is sacrilegious audacity to make nothing and God equal, as when we wish to make what has been born of God such as what has been made by Him out of nothing.
Naturae corruptibiles, quia ex nihilo factae. Omnes igitur naturae corruptibiles, nec omnino naturae essent, nisi a Deo essent; nec corruptibiles essent, si de illo essent, quia hoc quod ipse est essent. Ideo ergo quocumque modo, quacumque specie, quocumque ordine sunt, quia Deus est a quo factae sunt: ideo autem non incommutabiles sunt, quia nihil est unde factae sunt. Sacrilega enim audacia coaequantur nihil et Deus, si quale est illud quod de Deo natum est, tale velimus esse illud quod ab eo de nihilo factum est.
