Whether the foreknowledge of merits is the cause of predestination?
Objection 1: It seems that foreknowledge of merits is the cause of predestination. For the Apostle says ( Rom. 8:29 ): "Whom He foreknew, He also predestined." Again a gloss of Ambrose on Rom. 9:15 : "I will have mercy upon whom I will have mercy" says: "I will give mercy to him who, I foresee, will turn to Me with his whole heart." Therefore it seems the foreknowledge of merits is the cause of predestination.
Objection 2: Further, Divine predestination includes the divine will, which by no means can be irrational; since predestination is "the purpose to have mercy," as Augustine says (De Praed. Sanct. ii, 17). But there can be no other reason for predestination than the foreknowledge of merits. Therefore it must be the cause of reason of predestination.
Objection 3: Further, "There is no injustice in God" ( Rom. 9:14 ). Now it would seem unjust that unequal things be given to equals. But all men are equal as regards both nature and original sin; and inequality in them arises from the merits or demerits of their actions. Therefore God does not prepare unequal things for men by predestinating and reprobating, unless through the foreknowledge of their merits and demerits.
On the contrary, The Apostle says ( Titus 3:5 ): "Not by works of justice which we have done, but according to His mercy He saved us." But as He saved us, so He predestined that we should be saved. Therefore, foreknowledge of merits is not the cause or reason of predestination.
I answer that, Since predestination includes will, as was said above (A[4]), the reason of predestination must be sought for in the same way as was the reason of the will of God. Now it was shown above (Q[19], A[5] ), that we cannot assign any cause of the divine will on the part of the act of willing; but a reason can be found on the part of the things willed; inasmuch as God wills one thing on account of something else. Wherefore nobody has been so insane as to say that merit is the cause of divine predestination as regards the act of the predestinator. But this is the question, whether, as regards the effect, predestination has any cause; or what comes to the same thing, whether God pre-ordained that He would give the effect of predestination to anyone on account of any merits.
Accordingly there were some who held that the effect of predestination was pre-ordained for some on account of pre-existing merits in a former life. This was the opinion of Origen, who thought that the souls of men were created in the beginning, and according to the diversity of their works different states were assigned to them in this world when united with the body. The Apostle, however, rebuts this opinion where he says ( Rom. 9:11 , 12 ): "For when they were not yet born, nor had done any good or evil . . . not of works, but of Him that calleth, it was said of her: The elder shall serve the younger."
Others said that pre-existing merits in this life are the reason and cause of the effect of predestination. For the Pelagians taught that the beginning of doing well came from us; and the consummation from God: so that it came about that the effect of predestination was granted to one, and not to another, because the one made a beginning by preparing, whereas the other did not. But against this we have the saying of the Apostle ( 2 Cor. 3:5 ), that "we are not sufficient to think anything of ourselves as of ourselves." Now no principle of action can be imagined previous to the act of thinking. Wherefore it cannot be said that anything begun in us can be the reason of the effect of predestination.
And so others said that merits following the effect of predestination are the reason of predestination; giving us to understand that God gives grace to a person, and pre-ordains that He will give it, because He knows beforehand that He will make good use of that grace, as if a king were to give a horse to a soldier because he knows he will make good use of it. But these seem to have drawn a distinction between that which flows from grace, and that which flows from free will, as if the same thing cannot come from both. It is, however, manifest that what is of grace is the effect of predestination; and this cannot be considered as the reason of predestination, since it is contained in the notion of predestination. Therefore, if anything else in us be the reason of predestination, it will outside the effect of predestination. Now there is no distinction between what flows from free will, and what is of predestination; as there is not distinction between what flows from a secondary cause and from a first cause. For the providence of God produces effects through the operation of secondary causes, as was above shown (Q[22], A[3]). Wherefore, that which flows from free-will is also of predestination. We must say, therefore, that the effect of predestination may be considered in a twofold light---in one way, in particular; and thus there is no reason why one effect of predestination should not be the reason or cause of another; a subsequent effect being the reason of a previous effect, as its final cause; and the previous effect being the reason of the subsequent as its meritorious cause, which is reduced to the disposition of the matter. Thus we might say that God pre-ordained to give glory on account of merit, and that He pre-ordained to give grace to merit glory. In another way, the effect of predestination may be considered in general. Thus, it is impossible that the whole of the effect of predestination in general should have any cause as coming from us; because whatsoever is in man disposing him towards salvation, is all included under the effect of predestination; even the preparation for grace. For neither does this happen otherwise than by divine help, according to the prophet Jeremias ( Lam. 5:21 ): "convert us, O Lord, to Thee, and we shall be converted." Yet predestination has in this way, in regard to its effect, the goodness of God for its reason; towards which the whole effect of predestination is directed as to an end; and from which it proceeds, as from its first moving principle.
Reply to Objection 1: The use of grace foreknown by God is not the cause of conferring grace, except after the manner of a final cause; as was explained above.
Reply to Objection 2: Predestination has its foundation in the goodness of God as regards its effects in general. Considered in its particular effects, however, one effect is the reason of another; as already stated.
Reply to Objection 3: The reason for the predestination of some, and reprobation of others, must be sought for in the goodness of God. Thus He is said to have made all things through His goodness, so that the divine goodness might be represented in things. Now it is necessary that God's goodness, which in itself is one and undivided, should be manifested in many ways in His creation; because creatures in themselves cannot attain to the simplicity of God. Thus it is that for the completion of the universe there are required different grades of being; some of which hold a high and some a low place in the universe. That this multiformity of grades may be preserved in things, God allows some evils, lest many good things should never happen, as was said above (Q[22], A[2]). Let us then consider the whole of the human race, as we consider the whole universe. God wills to manifest His goodness in men; in respect to those whom He predestines, by means of His mercy, as sparing them; and in respect of others, whom he reprobates, by means of His justice, in punishing them. This is the reason why God elects some and rejects others. To this the Apostle refers, saying ( Rom. 9:22 , 23 ): "What if God, willing to show His wrath [that is, the vengeance of His justice], and to make His power known, endured [that is, permitted] with much patience vessels of wrath, fitted for destruction; that He might show the riches of His glory on the vessels of mercy, which He hath prepared unto glory" and ( 2 Tim. 2:20 ): "But in a great house there are not only vessels of gold and silver; but also of wood and of earth; and some, indeed, unto honor, but some unto dishonor." Yet why He chooses some for glory, and reprobates others, has no reason, except the divine will. Whence Augustine says (Tract. xxvi. in Joan.): "Why He draws one, and another He draws not, seek not to judge, if thou dost not wish to err." Thus too, in the things of nature, a reason can be assigned, since primary matter is altogether uniform, why one part of it was fashioned by God from the beginning under the form of fire, another under the form of earth, that there might be a diversity of species in things of nature. Yet why this particular part of matter is under this particular form, and that under another, depends upon the simple will of God; as from the simple will of the artificer it depends that this stone is in part of the wall, and that in another; although the plan requires that some stones should be in this place, and some in that place. Neither on this account can there be said to be injustice in God, if He prepares unequal lots for not unequal things. This would be altogether contrary to the notion of justice, if the effect of predestination were granted as a debt, and not gratuitously. In things which are given gratuitously, a person can give more or less, just as he pleases (provided he deprives nobody of his due), without any infringement of justice. This is what the master of the house said: "Take what is thine, and go thy way. Is it not lawful for me to do what I will?" ( Matt. 20:14 , 15 ).
Whether predestination is certain?
Objection 1: It seems that predestination is not certain. Because on the words "Hold fast that which thou hast, that no one take thy crown," ( Rev 3:11 ), Augustine says (De Corr. et Grat. 15): "Another will not receive, unless this one were to lose it." Hence the crown which is the effect of predestination can be both acquired and lost. Therefore predestination cannot be certain.
Objection 2: Further, granted what is possible, nothing impossible follows. But it is possible that one predestined---e.g. Peter---may sin and then be killed. But if this were so, it would follow that the effect of predestination would be thwarted. This then, is not impossible. Therefore predestination is not certain.
Objection 3: Further, whatever God could do in the past, He can do now. But He could have not predestined whom He hath predestined. Therefore now He is able not to predestine him. Therefore predestination is not certain.
On the contrary, A gloss on Rom. 8:29 : "Whom He foreknew, He also predestinated", says: "Predestination is the foreknowledge and preparation of the benefits of God, by which whosoever are freed will most certainly be freed."
I answer that, Predestination most certainly and infallibly takes effect; yet it does not impose any necessity, so that, namely, its effect should take place from necessity. For it was said above (A[1]), that predestination is a part of providence. But not all things subject to providence are necessary; some things happening from contingency, according to the nature of the proximate causes, which divine providence has ordained for such effects. Yet the order of providence is infallible, as was shown above (Q[22], A[4]). So also the order of predestination is certain; yet free-will is not destroyed; whence the effect of predestination has its contingency. Moreover all that has been said about the divine knowledge and will (Q[14], A[13]; Q[19], A[4]) must also be taken into consideration; since they do not destroy contingency in things, although they themselves are most certain and infallible.
Reply to Objection 1: The crown may be said to belong to a person in two ways; first, by God's predestination, and thus no one loses his crown: secondly, by the merit of grace; for what we merit, in a certain way is ours; and thus anyone may lose his crown by mortal sin. Another person receives that crown thus lost, inasmuch as he takes the former's place. For God does not permit some to fall, without raising others; according to Job 34:24 : "He shall break in pieces many and innumerable, and make others to stand in their stead." Thus men are substituted in the place of the fallen angels; and the Gentiles in that of the Jews. He who is substituted for another in the state of grace, also receives the crown of the fallen in that in eternal life he will rejoice at the good the other has done, in which life he will rejoice at all good whether done by himself or by others.
Reply to Objection 2: Although it is possible for one who is predestinated considered in himself to die in mortal sin; yet it is not possible, supposed, as in fact it is supposed. that he is predestinated. Whence it does not follow that predestination can fall short of its effect.
Reply to Objection 3: Since predestination includes the divine will as stated above (A[4]): and the fact that God wills any created thing is necessary on the supposition that He so wills, on account of the immutability of the divine will, but is not necessary absolutely; so the same must be said of predestination. Wherefore one ought not to say that God is able not to predestinate one whom He has predestinated, taking it in a composite sense, thought, absolutely speaking, God can predestinate or not. But in this way the certainty of predestination is not destroyed.
Whether the number of the predestined is certain?
Objection 1: It seems that the number of the predestined is not certain. For a number to which an addition can be made is not certain. But there can be an addition to the number of the predestined as it seems; for it is written ( Dt. 1:11 ): "The Lord God adds to this number many thousands," and a gloss adds, "fixed by God, who knows those who belong to Him." Therefore the number of the predestined is not certain.
Objection 2: Further, no reason can be assigned why God pre-ordains to salvation one number of men more than another. But nothing is arranged by God without a reason. Therefore the number to be saved pre-ordained by God cannot be certain.
Objection 3: Further, the operations of God are more perfect than those of nature. But in the works of nature, good is found in the majority of things; defect and evil in the minority. If, then, the number of the saved were fixed by God at a certain figure, there would be more saved than lost. Yet the contrary follows from Matt. 7:13 , 14 : "For wide is the gate, and broad the way that leadeth to destruction, and many there are who go in thereat. How narrow is the gate, and strait is the way that leadeth to life; and few there are who find it!" Therefore the number of those pre-ordained by God to be saved is not certain.
