Aquinas God’s Omnibenevolence

It is written: “God is love” (John 4:16).

We must needs assert that in God there is love: because love is the first movement of the will and of every appetitive faculty.

For since the acts of the will and of every appetitive faculty tend towards good and evil, as to their proper objects: and since good is essentially and especially the object of the will and the appetite, whereas evil is only the object secondarily and indirectly, as opposed to good; it follows that the acts of the will and appetite that regard good must naturally be prior to those that regard evil; thus, for instance, joy is prior to sorrow, love to hate: because what exists of itself is always prior to that which exists through another. Again, the more universal is naturally prior to what is less so. Hence the intellect is first directed to universal truth; and in the second place to particular and special truths. Now there are certain acts of the will and appetite that regard good under some special condition, as joy and delight regard good present and possessed; whereas desire and hope regard good not as yet possessed. Love, however, regards good universally, whether possessed or not. Hence love is naturally the first act of the will and appetite; for which reason all the other appetite movements presuppose love, as their root and origin. For nobody desires anything nor rejoices in anything, except as a good that is loved: nor is anything an object of hate except as opposed to the object of love. Similarly, it is clear that sorrow, and other things like to it, must be referred to love as to their first principle. Hence, in whomsoever there is will and appetite, there must also be love: since if the first is wanting, all that follows is also wanting. Now it has been shown that will is in God (19, 1), and hence we must attribute love to Him.

It is said (Wisdom 11:25): “Thou lovest all things that are, and hatest none of the things which Thou hast made.”
God loves all existing things. For all existing things, in so far as they exist, are good, since the existence of a thing is itself a good; and likewise, whatever perfection it possesses. Now it has been shown above (Question 19, Article 4) that God’s will is the cause of all things. It must needs be, therefore, that a thing has existence, or any kind of good, only inasmuch as it is willed by God. To every existing thing, then, God wills some good. Hence, since to love anything is nothing else than to will good to that thing, it is manifest that God loves everything that exists. Yet not as we love.
