Summa Theologica, Part I (Prima Pars) From the Complete...

Reply Obj. 3: The intelligible object moves our human intellect, so far as, in a way, it impresses on it its own likeness, by means of which the intellect is able to understand it. But the likenesses which God impresses on the created intellect are not sufficient to enable the created intellect to understand Him through His Essence, as we have seen above (Q. 12, A. 2; Q. 56, A. 3). Hence He moves the created intellect, and yet He cannot be intelligible to it, as we have explained (Q. 12, A. 4). _______________________

Obj. 2: Further, God cannot make two contradictories to be true at the same time. But this would follow if He moved the will; for to be voluntarily moved means to be moved from within, and not by another. Therefore God cannot move the will.

Obj. 3: Further, movement is attributed to the mover rather than to the one moved; wherefore homicide is not ascribed to the stone, but to the thrower. Therefore, if God moves the will, it follows that voluntary actions are not imputed to man for reward or blame. But this is false. Therefore God does not move the will.

I answer that, As the intellect is moved by the object and by the Giver of the power of intelligence, as stated above (A. 3), so is the will moved by its object, which is good, and by Him who creates the power of willing. Now the will can be moved by good as its object, but by God alone sufficiently and efficaciously. For nothing can move a movable thing sufficiently unless the active power of the mover surpasses or at least equals the potentiality of the thing movable. Now the potentiality of the will extends to the universal good; for its object is the universal good; just as the object of the intellect is the universal being. But every created good is some particular good; God alone is the universal good. Whereas He alone fills the capacity of the will, and moves it sufficiently as its object. In like manner the power of willing is caused by God alone. For to will is nothing but to be inclined towards the object of the will, which is universal good. But to incline towards the universal good belongs to the First Mover, to Whom the ultimate end is proportionate; just as in human affairs to him that presides over the community belongs the directing of his subjects to the common weal. Wherefore in both ways it belongs to God to move the will; but especially in the second way by an interior inclination of the will.

Reply Obj. 1: A thing moved by another is forced if moved against its natural inclination; but if it is moved by another giving to it the proper natural inclination, it is not forced; as when a heavy body is made to move downwards by that which produced it, then it is not forced. In like manner God, while moving the will, does not force it, because He gives the will its own natural inclination.

Reply Obj. 2: To be moved voluntarily, is to be moved from within, that is, by an interior principle: yet this interior principle may be caused by an exterior principle; and so to be moved from within is not repugnant to being moved by another.

Reply Obj. 3: If the will were so moved by another as in no way to be moved from within itself, the act of the will would not be imputed for reward or blame. But since its being moved by another does not prevent its being moved from within itself, as we have stated (ad 2), it does not thereby forfeit the motive for merit or demerit. _______________________

Objection 1: It would seem that God does not work in every agent. For we must not attribute any insufficiency to God. If therefore God works in every agent, He works sufficiently in each one. Hence it would be superfluous for the created agent to work at all.

Obj. 2: Further, the same work cannot proceed at the same time from two sources; as neither can one and the same movement belong to two movable things. Therefore if the creature's operation is from God operating in the creature, it cannot at the same time proceed from the creature; and so no creature works at all.

Obj. 3: Further, the maker is the cause of the operation of the thing made, as giving it the form whereby it operates. Therefore, if God is the cause of the operation of things made by Him, this would be inasmuch as He gives them the power of operating. But this is in the beginning, when He makes them. Thus it seems that God does not operate any further in the operating creature.

I answer that, Some have understood God to work in every agent in such a way that no created power has any effect in things, but that God alone is the ultimate cause of everything wrought; for instance, that it is not fire that gives heat, but God in the fire, and so forth. But this is impossible. First, because the order of cause and effect would be taken away from created things: and this would imply lack of power in the Creator: for it is due to the power of the cause, that it bestows active power on its effect. Secondly, because the active powers which are seen to exist in things, would be bestowed on things to no purpose, if these wrought nothing through them. Indeed, all things created would seem, in a way, to be purposeless, if they lacked an operation proper to them; since the purpose of everything is its operation. For the less perfect is always for the sake of the more perfect: and consequently as the matter is for the sake of the form, so the form which is the first act, is for the sake of its operation, which is the second act; and thus operation is the end of the creature. We must therefore understand that God works in things in such a manner that things have their proper operation.

In order to make this clear, we must observe that as there are few kinds of causes; matter is not a principle of action, but is the subject that receives the effect of action. On the other hand, the end, the agent, and the form are principles of action, but in a certain order. For the first principle of action is the end which moves the agent; the second is the agent; the third is the form of that which the agent applies to action (although the agent also acts through its own form); as may be clearly seen in things made by art. For the craftsman is moved to action by the end, which is the thing wrought, for instance a chest or a bed; and applies to action the axe which cuts through its being sharp.

Thus then does God work in every worker, according to these three things. First as an end. For since every operation is for the sake of some good, real or apparent; and nothing is good either really or apparently, except in as far as it participates in a likeness to the Supreme Good, which is God; it follows that God Himself is the cause of every operation as its end. Again it is to be observed that where there are several agents in order, the second always acts in virtue of the first; for the first agent moves the second to act. And thus all agents act in virtue of God Himself: and therefore He is the cause of action in every agent. Thirdly, we must observe that God not only moves things to operate, as it were applying their forms and powers to operation, just as the workman applies the axe to cut, who nevertheless at times does not give the axe its form; but He also gives created agents their forms and preserves them in being. Therefore He is the cause of action not only by giving the form which is the principle of action, as the generator is said to be the cause of movement in things heavy and light; but also as preserving the forms and powers of things; just as the sun is said to be the cause of the manifestation of colors, inasmuch as it gives and preserves the light by which colors are made manifest.

And since the form of a thing is within the thing, and all the more, as it approaches nearer to the First and Universal Cause; and because in all things God Himself is properly the cause of universal being which is innermost in all things; it follows that in all things God works intimately. For this reason in Holy Scripture the operations of nature are attributed to God as operating in nature, according to Job 10:11: "Thou hast clothed me with skin and flesh: Thou hast put me together with bones and sinews."

Objection 1: It would seem that God cannot do anything outside the established order of nature. For Augustine (Contra Faust. xxvi, 3) says: "God the Maker and Creator of each nature, does nothing against nature." But that which is outside the natural order seems to be against nature. Therefore God can do nothing outside the natural order.

I answer that, From each cause there results a certain order to its effects, since every cause is a principle; and so, according to the multiplicity of causes, there results a multiplicity of orders, subjected one to the other, as cause is subjected to cause. Wherefore a higher cause is not subjected to a cause of a lower order; but conversely. An example of this may be seen in human affairs. On the father of a family depends the order of the household; which order is contained in the order of the city; which order again depends on the ruler of the city; while this last order depends on that of the king, by whom the whole kingdom is ordered.

If therefore we consider the order of things depending on the first cause, God cannot do anything against this order; for, if He did so, He would act against His foreknowledge, or His will, or His goodness. But if we consider the order of things depending on any secondary cause, thus God can do something outside such order; for He is not subject to the order of secondary causes; but, on the contrary, this order is subject to Him, as proceeding from Him, not by a natural necessity, but by the choice of His own will; for He could have created another order of things. Wherefore God can do something outside this order created by Him, when He chooses, for instance by producing the effects of secondary causes without them, or by producing certain effects to which secondary causes do not extend. So Augustine says (Contra Faust. xxvi, 3): "God acts against the wonted course of nature, but by no means does He act against the supreme law; because He does not act against Himself."

Reply Obj. 1: In natural things something may happen outside this natural order, in two ways. It may happen by the action of an agent which did not give them their natural inclination; as, for example, when a man moves a heavy body upwards, which does not owe to him its natural inclination to move downwards; and that would be against nature. It may also happen by the action of the agent on whom the natural inclination depends; and this is not against nature, as is clear in the ebb and flow of the tide, which is not against nature; although it is against the natural movement of water in a downward direction; for it is owing to the influence of a heavenly body, on which the natural inclination of lower bodies depends. Therefore since the order of nature is given to things by God; if He does anything outside this order, it is not against nature. Wherefore Augustine says (Contra Faust. xxvi, 3): "That is natural to each thing which is caused by Him from Whom is all mode, number, and order in nature."

Reply Obj. 3: God fixed a certain order in things in such a way that at the same time He reserved to Himself whatever he intended to do otherwise than by a particular cause. So when He acts outside this order, He does not change. _______________________

Objection 1: It would seem that not everything which God does outside the natural order of things, is miraculous. For the creation of the world, and of souls, and the justification of the unrighteous, are done by God outside the natural order; as not being accomplished by the action of any natural cause. Yet these things are not called miracles. Therefore not everything that God does outside the natural order is a miracle.

Obj. 2: Further, a miracle is "something difficult, which seldom occurs, surpassing the faculty of nature, and going so far beyond our hopes as to compel our astonishment" [*St. Augustine, De utilitate credendi xvi.]. But some things outside the order of nature are not arduous; for they occur in small things, such as the recovery and healing of the sick. Nor are they of rare occurrence, since they happen frequently; as when the sick were placed in the streets, to be healed by the shadow of Peter (Acts 5:15). Nor do they surpass the faculty of nature; as when people are cured of a fever. Nor are they beyond our hopes, since we all hope for the resurrection of the dead, which nevertheless will be outside the course of nature. Therefore not all things are outside the course of nature are miraculous.
