SUMMA THEOLOGICA. Thomas Aquinas
Further, the willed moves the willer, as the appetible the appetite, as stated in De Anima iii, 54. If, therefore, God wills anything apart from Himself, His will must be moved by another; which is impossible.
Objection 3: Further, if what is willed suffices the willer, he seeks nothing beyond it. But His own goodness suffices God, and completely satisfies His will. Therefore God does not will anything apart from Himself.
Objection 4: Further, acts of will are multiplied in proportion to the number of their objects. If, therefore, God wills Himself and things apart from Himself, it follows that the act of His will is manifold, and consequently His existence, which is His will. But this is impossible. Therefore God does not will things apart from Himself.
On the contrary, The Apostle says (1 Thess. 4:3): "This is the will of God, your sanctification."
I answer that, God wills not only Himself, but other things apart from Himself. This is clear from the comparison which we made above ( Article [1]). For natural things have a natural inclination not only towards their own proper good, to acquire it if not possessed, and, if possessed, to rest therein; but also to spread abroad their own good amongst others, so far as possible. Hence we see that every agent, in so far as it is perfect and in act, produces its like. It pertains, therefore, to the nature of the will to communicate as far as possible to others the good possessed; and especially does this pertain to the divine will, from which all perfection is derived in some kind of likeness. Hence, if natural things, in so far as they are perfect, communicate their good to others, much more does it appertain to the divine will to communicate by likeness its own good to others as much as possible. Thus, then, He wills both Himself to be, and other things to be; but Himself as the end, and other things as ordained to that end; inasmuch as it befits the divine goodness that other things should be partakers therein.
Reply to Objection 1: The divine will is God's own existence essentially, yet they differ in aspect, according to the different ways of understanding them and expressing them, as is clear from what has already been said ( Question [13], Article [4]). For when we say that God exists, no relation to any other object is implied, as we do imply when we say that God wills. Therefore, although He is not anything apart from Himself, yet He does will things apart from Himself.
Reply to Objection 2: In things willed for the sake of the end, the whole reason for our being moved is the end, and this it is that moves the will, as most clearly appears in things willed only for the sake of the end. He who wills to take a bitter draught, in doing so wills nothing else than health; and this alone moves his will. It is different with one who takes a draught that is pleasant, which anyone may will to do, not only for the sake of health, but also for its own sake. Hence, although God wills things apart from Himself only for the sake of the end, which is His own goodness, it does not follow that anything else moves His will, except His goodness. So, as He understands things apart from Himself by understanding His own essence, so He wills things apart from Himself by willing His own goodness.
Reply to Objection 3: From the fact that His own goodness suffices the divine will, it does not follow that it wills nothing apart from itself, but rather that it wills nothing except by reason of its goodness. Thus, too, the divine intellect, though its perfection consists in its very knowledge of the divine essence, yet in that essence knows other things.
Reply to Objection 4: As the divine intellect is one, as seeing the many only in the one, in the same way the divine will is one and simple, as willing the many only through the one, that is, through its own goodness.
Whether whatever God wills He wills necessarily?
Objection 1: It seems that whatever God wills He wills necessarily. For everything eternal is necessary. But whatever God wills, He wills from eternity, for otherwise His will would be mutable. Therefore whatever He wills, He wills necessarily.
Objection 2: Further, God wills things apart from Himself, inasmuch as He wills His own goodness. Now God wills His own goodness necessarily. Therefore He wills things apart from Himself necessarily.
Objection 3: Further, whatever belongs to the nature of God is necessary, for God is of Himself necessary being, and the principle of all necessity, as above shown ( Question [2], Article [3]). But it belongs to His nature to will whatever He wills; since in God there can be nothing over and above His nature as stated in Metaph. v, 6. Therefore whatever He wills, He wills necessarily.
Objection 4: Further, being that is not necessary, and being that is possible not to be, are one and the same thing. If, therefore, God does not necessarily will a thing that He wills, it is possible for Him not to will it, and therefore possible for Him to will what He does not will. And so the divine will is contingent upon one or the other of two things, and imperfect, since everything contingent is imperfect and mutable.
Objection 5: Further, on the part of that which is indifferent to one or the other of two things, no action results unless it is inclined to one or the other by some other power, as the Commentator [*Averroes] says in Phys. ii. If, then, the Will of God is indifferent with regard to anything, it follows that His determination to act comes from another; and thus He has some cause prior to Himself.
Objection 6: Further, whatever God knows, He knows necessarily. But as the divine knowledge is His essence, so is the divine will. Therefore whatever God wills, He wills necessarily.
On the contrary, The Apostle says (Eph. 1:11): "Who worketh all things according to the counsel of His will." Now, what we work according to the counsel of the will, we do not will necessarily. Therefore God does not will necessarily whatever He wills.
I answer that, There are two ways in which a thing is said to be necessary, namely, absolutely, and by supposition. We judge a thing to be absolutely necessary from the relation of the terms, as when the predicate forms part of the definition of the subject: thus it is absolutely necessary that man is an animal. It is the same when the subject forms part of the notion of the predicate; thus it is absolutely necessary that a number must be odd or even. In this way it is not necessary that Socrates sits: wherefore it is not necessary absolutely, though it may be so by supposition; for, granted that he is sitting, he must necessarily sit, as long as he is sitting. Accordingly as to things willed by God, we must observe that He wills something of absolute necessity: but this is not true of all that He wills. For the divine will has a necessary relation to the divine goodness, since that is its proper object. Hence God wills His own goodness necessarily, even as we will our own happiness necessarily, and as any other faculty has necessary relation to its proper and principal object, for instance the sight to color, since it tends to it by its own nature. But God wills things apart from Himself in so far as they are ordered to His own goodness as their end. Now in willing an end we do not necessarily will things that conduce to it, unless they are such that the end cannot be attained without them; as, we will to take food to preserve life, or to take ship in order to cross the sea. But we do not necessarily will things without which the end is attainable, such as a horse for a journey which we can take on foot, for we can make the journey without one. The same applies to other means. Hence, since the goodness of God is perfect, and can exist without other things inasmuch as no perfection can accrue to Him from them, it follows that His willing things apart from Himself is not absolutely necessary. Yet it can be necessary by supposition, for supposing that He wills a thing, then He is unable not to will it, as His will cannot change.
Reply to Objection 1: From the fact that God wills from eternity whatever He wills, it does not follow that He wills it necessarily; except by supposition.
