Summa Theologica

We must now consider the division of grace; under which head there are five points of inquiry:

(1) Whether grace is fittingly divided into gratuitous grace and sanctifying grace?

(2) Of the division into operating and cooperating grace;

(3) Of the division of it into prevenient and subsequent grace;

(4) Of the division of gratuitous grace;

(5) Of the comparison between sanctifying and gratuitous grace.
