know it before; hence we take counsel in order to know what is good for us. Now it has already been shown that both the substance of God and His knowledge are entirely unchangeable ( Question [9], Article [1]; Question [14], Article [15]). Therefore His will must be entirely unchangeable.
Reply to Objection 1: These words of the Lord are to be understood metaphorically, and according to the likeness of our nature. For when we repent, we destroy what we have made; although we may even do so without change of will; as, when a man wills to make a thing, at the same time intending to destroy it later. Therefore God is said to have repented, by way of comparison with our mode of acting, in so far as by the deluge He destroyed from the face of the earth man whom He had made.
Reply to Objection 2: The will of God, as it is the first and universal cause, does not exclude intermediate causes that have power to produce certain effects. Since however all intermediate causes are inferior in power to the first cause, there are many things in the divine power, knowledge and will that are not included in the order of inferior causes. Thus in the case of the raising of Lazarus, one who looked only on inferior causes might have said: "Lazarus will not rise again," but looking at the divine first cause might have said: "Lazarus will rise again." And God wills both: that is, that in the order of the inferior cause a thing shall happen; but that in the order of the higher cause it shall not happen; or He may will conversely. We may say, then, that God sometimes declares that a thing shall happen according as it falls under the order of inferior causes, as of nature, or merit, which yet does not happen as not being in the designs of the divine and higher cause. Thus He foretold to Ezechias: "Take order with thy house, for thou shalt die, and not live" (Is. 38:1). Yet this did not take place, since from eternity it was otherwise disposed in the divine knowledge and will, which is unchangeable. Hence Gregory says (Moral. xvi, 5): "The sentence of God changes, but not His counsel"---that is to say, the counsel of His will. When therefore He says, "I also will repent," His words must be understood metaphorically. For men seem to repent, when they do not fulfill what they have threatened.
Reply to Objection 3: It does not follow from this argument that God has a will that changes, but that He sometimes wills that things should change.
Reply to Objection 4: Although God's willing a thing is not by absolute necessity, yet it is necessary by supposition, on account of the unchangeableness of the divine will, as has been said above ( Article [3]).
Whether the will of God imposes necessity on the things willed?
Objection 1: It seems that the will of God imposes necessity on the things willed. For Augustine says (Enchiridion 103): "No one is saved, except whom God has willed to be saved. He must therefore be asked to will it; for if He wills it, it must necessarily be."
Objection 2: Further, every cause that cannot be hindered, produces its effect necessarily, because, as the Philosopher says (Phys. ii, 84) "Nature always works in the same way, if there is nothing to hinder it." But the will of God cannot be hindered. For the Apostle says (Rm. 9:19): "Who resisteth His will?" Therefore the will of God imposes necessity on the things willed.
Objection 3: Further, whatever is necessary by its antecedent cause is necessary absolutely; it is thus necessary that animals should die, being compounded of contrary elements. Now things created by God are related to the divine will as to an antecedent cause, whereby they have necessity. For the conditional statement is true that if God wills a thing, it comes to pass; and every true conditional statement is necessary. It follows therefore that all that God wills is necessary absolutely.
On the contrary, All good things that exist God wills to be. If therefore His will imposes necessity on things willed, it follows that all good happens of necessity; and thus there is an end of free will, counsel, and all other such things.
I answer that, The divine will imposes necessity on some things willed but not on all. The reason of this some have chosen to assign to intermediate causes, holding that what God produces by necessary causes is necessary; and what He produces by contingent causes contingent.
This does not seem to be a sufficient explanation, for two reasons. First, because the effect of a first cause is contingent on account of the secondary cause, from the fact that the effect of the first cause is hindered by deficiency in the second cause, as the sun's power is hindered by a defect in the plant. But no defect of a secondary cause can hinder God's will from producing its effect. Secondly, because if the distinction between the contingent and the necessary is to be referred only to secondary causes, this must be independent of the divine intention and will; which is inadmissible. It is better therefore to say that this happens on account of the efficacy of the divine will. For when a cause is efficacious to act, the effect follows upon the cause, not only as to the thing done, but also as to its manner of being done or of being. Thus from defect of active power in the seed it may happen that a child is born unlike its father in accidental points, that belong to its manner of being. Since then the divine will is perfectly efficacious, it follows not only that things are done, which God wills to be done, but also that they are done in the way that He wills. Now God wills some things to be done necessarily, some contingently, to the right ordering of things, for the building up of the universe. Therefore to some effects He has attached necessary causes, that cannot fail; but to others defectible and contingent causes, from which arise contingent effects. Hence it is not because the proximate causes are contingent that the effects willed by God happen contingently, but because God prepared contingent causes for them, it being His will that they should happen contingently.
Reply to Objection 1: By the words of Augustine we must understand a necessity in things willed by God that is not absolute, but conditional. For the conditional statement that if God wills a thing it must necessarily be, is necessarily true.
Reply to Objection 2: From the very fact that nothing resists the divine will, it follows that not only those things happen that God wills to happen, but that they happen necessarily or contingently according to His will.
Reply to Objection 3: Consequents have necessity from their antecedents according to the mode of the antecedents. Hence things effected by the divine will have that kind of necessity that God wills them to have, either absolute or conditional. Not all things, therefore, are absolute necessities.
Whether God wills evils?
Objection 1: It seems that God wills evils. For every good that exists, God wills. But it is a good that evil should exist. For Augustine says (Enchiridion 95): "Although evil in so far as it is evil is not a good, yet it is good that not only good things should exist, but also evil things." Therefore God wills evil things.
Objection 2: Further, Dionysius says (Div. Nom. iv, 23): "Evil would conduce to the perfection of everything," i.e. the universe. And Augustine says (Enchiridion 10,11): "Out of all things is built up the admirable beauty of the universe, wherein even that which is called evil, properly ordered and disposed, commends the good more evidently in that good is more pleasing and praiseworthy when contrasted with evil." But God wills all that appertains to the perfection and beauty of the universe, for this is what God desires above all things in His creatures. Therefore God wills evil.
Objection 3: Further, that evil
