I answer that, Some have said that meritorious works deadened by subsequent sin are not revived by the ensuing Penance, because they deemed such works to have passed away, so that they could not be revived. But that is no reason why they should not be revived: because they are conducive to eternal life (wherein their life consists) not only as actually existing, but also after they cease to exist actually, and as abiding in the Divine acceptance. Now, they abide thus, so far as they are concerned, even after they have been deadened by sin, because those works, according as they were done, will ever be acceptable to God and give joy to the saints, according to Apoc. 3:11: "Hold fast that which thou hast, that no man take thy crown." That they fail in their efficacy to bring the man, who did them, to eternal life, is due to the impediment of the supervening sin whereby he is become unworthy of eternal life. But this impediment is removed by Penance, inasmuch as sins are taken away thereby. Hence it follows that deeds previously deadened, recover, through Penance, their efficacy in bringing him, who did them, to eternal life, and, in other words, they are revived. It is therefore evident that deadened works are revived by Penance.
Reply Obj. 1: The very works themselves of sin are removed by Penance, so that, by God's mercy, no further stain or debt of punishment is incurred on their account: on the other hand, works done in charity are not removed by God, since they abide in His acceptance, but they are hindered on the part of the man who does them; wherefore if this hindrance, on the part of the man who does those works, be removed, God on His side fulfills what those works deserved.
Reply Obj. 2: Deeds done in charity are not in themselves deadened, as explained above, but only with regard to a supervening impediment on the part of the man who does them. On the other hand, an animal dies in itself, through being deprived of the principle of life: so that the comparison fails.
Reply Obj. 3: He who, through Penance, arises to lesser charity, will receive the essential reward according to the degree of charity in which he is found. Yet he will have greater joy for the works he had done in his former charity, than for those which he did in his subsequent charity: and this joy belongs to the accidental reward. _______________________
SIXTH ARTICLE [III, Q. 89, Art. 6]
Whether the Effect of Subsequent Penance Is to Quicken Even Dead
Works?
Objection 1: It would seem that the effect of subsequent Penance is to quicken even dead works, those, namely, that were not done in charity. For it seems more difficult to bring to life that which has been deadened, since this is never done naturally, than to quicken that which never had life, since certain living things are engendered naturally from things without life. Now deadened works are revived by Penance, as stated above (A. 5). Much more, therefore, are dead works revived.
Obj. 2: Further, if the cause be removed, the effect is removed. But the cause of the lack of life in works generically good done without charity, was the lack of charity and grace, which lack is removed by Penance. Therefore dead works are quickened by charity.
Obj. 3: Further, Jerome in commenting on Agg. i, 6: "You have sowed much," says: "If at any time you find a sinner, among his many evil deeds, doing that which is right, God is not so unjust as to forget the few good deeds on account of his many evil deeds." Now this seems to be the case chiefly when past evil deeds are removed by Penance. Therefore it seems that through Penance, God rewards the former deeds done in the state of sin, which implies that they are quickened.
On the contrary, The Apostle says (1 Cor. 13:3): "If I should distribute all my goods to feed the poor, and if I should deliver my body to be burned, and have not charity, it profiteth me nothing." But this would not be true, if, at least by subsequent Penance, they were quickened. Therefore Penance does not quicken works which before were dead.
