(CG 1/095). That God cannot will Evil (Book 1: Of God As He Is In Himself) (Summa Contra Gentiles) (Aquinas, Thomas, St.)

AS love is to good, so is hatred to evil; we wish good to them whom we love, and evil to them whom we hate. If then the will of God cannot be inclined to evil, as has been shown (Chap. XCV), it is impossible for Him to hate anything.

2. The will of God tends to things other than Himself inasmuch as, by willing and loving His own being and goodness, He wishes it to be diffused as far as is possible by communication of His likeness. This then is what God wills in beings other than Himself, that there be in them the likeness of His goodness. Therefore God wills the good of everything, and hates nothing.

4. What is found naturally in all active causes, must be found especially in the Prime Agent. But all agents in their own way love the effects which they themselves produce, as parents their children, poets their own poems, craftsmen their works. Much more therefore is God removed from hating anything, seeing that He is cause of all.

Hence it is said: You love all things that are, and hate nothing of the things that You have made (Wisd. xi, 25).

Some things however God is said, to hate figuratively (similitudinarie), and that in two ways. The first way is this, that God, in loving things and willing their good to be, wills their evil not to be: hence He is said to have hatred of evils, for the things we wish not to be we are said to hate. So it is said: Think no evil in your hearts every one of you against his friend, and love no lying oath: for all these are things that I hate, says the Lord (Zach. viii, 17). But none of these things are effects of creation: they are not as subsistent things, to which hatred or love properly attaches. The other way is by God's wishing some greater good, which cannot be without the privation of a lesser good; and thus He is said to hate, whereas it is more properly love. Thus inasmuch as He wills the good of justice, or of the order of the universe, which cannot be without the punishment or perishing of some, He is said to hate those beings whose punishment or perishing He wills, according to the text, Esau I have hated (Malach. i, 3); and, You hate all who work Iniquity, you will destroy all who utter falsehood: the man of blood and deceit the Lord shall abominate (Ps. v, 7).
