That there is no entity521 contrary to the divine, because nonentity seems to be that which is wholly opposite to Him who supremely and always is.
This may be enough to prevent anyone from supposing, when we speak of the apostate angels, that they could have another nature, derived, as it were, from some different origin, and not from God. From the great impiety of this error we shall disentangle ourselves the more readily and easily, the more distinctly we understand that which God spoke by the angel when He sent Moses to the children of Israel: “I am that I am.”522 For since God is the supreme existence, that is to say, supremely is, and is therefore unchangeable, the things that He made He empowered to be, but not to be supremely like Himself. To some He communicated a more ample, to others a more limited existence, and thus arranged the natures of beings in ranks. For as from sapere comes sapientia, so from esse comes essentia—a new word indeed, which the old Latin writers did not use, but which is naturalized in our day,523 that our language may not want an equivalent for the Greek οὐσία. For this is expressed word for word by essentia. Consequently, to that nature which supremely is, and which created all else that exists, no nature is contrary save that which does not exist. For nonentity is the contrary of that which is. And thus there is no being contrary to God, the Supreme Being, and Author of all beings whatsoever.

That the enemies of God are so, not by nature but by will, which, as it injures them, injures a good nature; for if vice does not injure, it is not vice.
In Scripture they are called God’s enemies who oppose His rule, not by nature, but by vice; having no power to hurt Him, but only themselves. For they are His enemies, not through their power to hurt, but by their will to oppose Him. For God is unchangeable, and wholly proof against injury. Therefore the vice which makes those who are called His enemies resist Him, is an evil not to God, but to themselves. And to them it is an evil, solely because it corrupts the good of their nature. It is not nature, therefore, but vice, which is contrary to God. For that which is evil is contrary to the good. And who will deny that God is the supreme good? Vice, therefore, is contrary to God, as evil to good. Further, the nature it vitiates is a good, and therefore to this good also it is contrary. But while it is contrary to God only as evil to good, it is contrary to the nature it vitiates, both as evil and as hurtful. For to God no evils are hurtful; but only to natures mutable and corruptible, though, by the testimony of the vices themselves, originally good. For were they not good, vices could not hurt them. For how do they hurt them but by depriving them of integrity, beauty, welfare, virtue, and, in short, whatever natural good vice is wont to diminish or destroy? But if there be no good to take away, then no injury can be done, and consequently there can be no vice. For it is impossible that there should be a harmless vice. Whence we gather, that though vice cannot injure the unchangeable good, it can injure nothing but good; because it does not exist where it does not injure. This, then, may be thus formulated: Vice cannot be in the highest good, and cannot be but in some good. Things solely good, therefore, can in some circumstances exist; things solely evil, never; for even those natures which are vitiated by an evil will, so far indeed as they are vitiated, are evil, but in so far as they are natures they are good. And when a vitiated nature is punished, besides the good it has
