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. 1: This argument shows that predestination is not furthered by the prayers of the saints, as regards the preordination.
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. _______________________
QUESTION 24
THE BOOK OF LIFE
(In Three Articles)
We now consider the book of life; concerning which there are three points of inquiry:
(1) What is the book of life?
(2) Of what life is it the book?
(3) Whether anyone can be blotted out of the book of life? _______________________
