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

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.

Obj. 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.

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 Obj. 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 Obj. 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 Obj. 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. _______________________

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 (Deut. 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.

Obj. 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.

I answer that, The number of the predestined is certain. Some have said that it was formally, but not materially certain; as if we were to say that it was certain that a hundred or a thousand would be saved; not however these or those individuals. But this destroys the certainty of predestination; of which we spoke above (A. 6). Therefore we must say that to God the number of the predestined is certain, not only formally, but also materially. It must, however, be observed that the number of the predestined is said to be certain to God, not by reason of His knowledge, because, that is to say, He knows how many will be saved (for in this way the number of drops of rain and the sands of the sea are certain to God); but by reason of His deliberate choice and determination. For the further evidence of which we must remember that every agent intends to make something finite, as is clear from what has been said above when we treated of the infinite (Q. 7, AA. 2 ,3). Now whosoever intends some definite measure in his effect thinks out some definite number in the essential parts, which are by their very nature required for the perfection of the whole. For of those things which are required not principally, but only on account of something else, he does not select any definite number per se; but he accepts and uses them in such numbers as are necessary on account of that other thing.

For instance, a builder thinks out the definite measurements of a house, and also the definite number of rooms which he wishes to make in the house; and definite measurements of the walls and roof; he does not, however, select a definite number of stones, but accepts and uses just so many as are sufficient for the required measurements of the wall. So also must we consider concerning God in regard to the whole universe, which is His effect. For He pre-ordained the measurements of the whole of the universe, and what number would befit the essential parts of that universe—that is to say, which have in some way been ordained in perpetuity; how many spheres, how many stars, how many elements, and how many species. Individuals, however, which undergo corruption, are not ordained as it were chiefly for the good of the universe, but in a secondary way, inasmuch as the good of the species is preserved through them. Whence, although God knows the total number of individuals, the number of oxen, flies and such like, is not pre-ordained by God per se; but divine providence produces just so many as are sufficient for the preservation of the species. Now of all creatures the rational creature is chiefly ordained for the good of the universe, being as such incorruptible; more especially those who attain to eternal happiness, since they more immediately reach the ultimate end. Whence the number of the predestined is certain to God; not only by way of knowledge, but also by way of a principal pre-ordination.

It is not exactly the same thing in the case of the number of the reprobate, who would seem to be pre-ordained by God for the good of the elect, in whose regard "all things work together unto good" (Rom. 8:28). Concerning the number of all the predestined, some say that so many men will be saved as angels fell; some, so many as there were angels left; others, as many as the number of angels created by God. It is, however, better to say that, "to God alone is known the number for whom is reserved eternal happiness [*From the 'secret' prayer of the missal, 'pro vivis et defunctis.']"

Reply Obj. 2: The reason of the quantity of any one part must be judged from the proportion of that part of the whole. Thus in God the reason why He has made so many stars, or so many species of things, or predestined so many, is according to the proportion of the principal parts to the good of the whole universe.

Reply Obj. 3: The good that is proportionate to the common state of nature is to be found in the majority; and is wanting in the minority. The good that exceeds the common state of nature is to be found in the minority, and is wanting in the majority. Thus it is clear that the majority of men have a sufficient knowledge for the guidance of life; and those who have not this knowledge are said to be half-witted or foolish; but they who attain to a profound knowledge of things intelligible are a very small minority in respect to the rest. Since their eternal happiness, consisting in the vision of God, exceeds the common state of nature, and especially in so far as this is deprived of grace through the corruption of original sin, those who are saved are in the minority. In this especially, however, appears the mercy of God, that He has chosen some for that salvation, from which very many in accordance with the common course and tendency of nature fall short. _______________________

Objection 1: It seems that predestination cannot be furthered by the prayers of the saints. For nothing eternal can be preceded by anything temporal; and in consequence nothing temporal can help towards making something else eternal. But predestination is eternal. Therefore, since the prayers of the saints are temporal, they cannot so help as to cause anyone to become predestined. Predestination therefore is not furthered by the prayers of the saints.

Obj. 2: Further, as there is no need of advice except on account of defective knowledge, so there is no need of help except through defective power. But neither of these things can be said of God when He predestines. Whence it is said: "Who hath helped the Spirit of the Lord? [*Vulg.: 'Who hath known the mind of the Lord?'] Or who hath been His counsellor?" (Rom. 11:34). Therefore predestination cannot be furthered by the prayers of the saints.

On the contrary, It is said that "Isaac besought the Lord for his wife because she was barren; and He heard him and made Rebecca to conceive" (Gen. 25:21). But from that conception Jacob was born, and he was predestined. Now his predestination would not have happened if he had never been born. Therefore predestination can be furthered by the prayers of the saints.

I answer that, Concerning this question, there were different errors. Some, regarding the certainty of divine predestination, said that prayers were superfluous, as also anything else done to attain salvation; because whether these things were done or not, the predestined would attain, and the reprobate would not attain, eternal salvation. But against this opinion are all the warnings of Holy Scripture, exhorting us to prayer and other good works.

Others declared that the divine predestination was altered through prayer. This is stated to have the opinion of the Egyptians, who thought that the divine ordination, which they called fate, could be frustrated by certain sacrifices and prayers. Against this also is the authority of Scripture. For it is said: "But the triumpher in Israel will not spare and will not be moved to repentance" (1 Kings 15:29); and that "the gifts and the calling of God are without repentance" (Rom. 11:29).

Wherefore we must say otherwise that in predestination two things are to be considered—namely, the divine ordination; and its effect. As regards the former, in no possible way can predestination be furthered by the prayers of the saints. For it is not due to their prayers that anyone is predestined by God. As regards the latter, predestination is said to be helped by the prayers of the saints, and by other good works; because providence, of which predestination is a part, does not do away with secondary causes but so provides effects, that the order of secondary causes falls also under providence. So, as natural effects are provided by God in such a way that natural causes are directed to bring about those natural effects, without which those effects would not happen; so the salvation of a person is predestined by God in such a way, that whatever helps that person towards salvation falls under the order of predestination; whether it be one's own prayers or those of another; or other good works, and such like, without which one would not attain to salvation. Whence, the predestined must strive after good works and prayer; because through these means predestination is most certainly fulfilled. For this reason it is said: "Labor more that by good works you may make sure your calling and election" (2 Pet. 1:10).

Reply Obj. 2: One is said to be helped by another in two ways; in one way, inasmuch as he receives power from him: and to be helped thus belongs to the weak; but this cannot be said of God, and thus we are to understand, "Who hath helped the Spirit of the Lord?" In another way one is said to be helped by a person through whom he carries out his work, as a master through a servant. In this way God is helped by us; inasmuch as we execute His orders, according to 1 Cor. 3:9: "We are God's co-adjutors." Nor is this on account of any defect in the power of God, but because He employs intermediary causes, in order that the beauty of order may be preserved in the universe; and also that He may communicate to creatures the dignity of causality.

Reply Obj. 3: Secondary causes cannot escape the order of the first universal cause, as has been said above (Q. 19, A. 6), indeed, they execute that order. And therefore predestination can be furthered by creatures, but it cannot be impeded by them. _______________________
