I answer that , God does reprobate some. For it was said above (Article 1) that predestination is a part of providence. To providence, however, it belongs to permit certain defects in those things which are subject to providence, as was said above (Question 22, Article 2). Thus, as men are ordained to eternal life through the providence of God, it likewise is part of that providence to permit some to fall away from that end; this is called reprobation. Thus, as predestination is a part of providence, in regard to those ordained to eternal salvation, so reprobation is a part of providence in regard to those who turn aside from that end. Hence reprobation implies not only foreknowledge, but also something more, as does providence, as was said above (Question 22, Article 1). Therefore, as predestination includes the will to confer grace and glory; so also reprobation includes the will to permit a person to fall into sin, and to impose the punishment of damnation on account of that sin.
Reply to Objection 1 . God loves all men and all creatures, inasmuch as He wishes them all some good; but He does not wish every good to them all. So far, therefore, as He does not wish this particular good—namely, eternal life—He is said to hate or reprobated them.
