Context

“This is said on account of venial sins, which are contrary, not to the habit, but to the act of charity: hence they are incompatible, not with the perfection of the way, but with that of heaven. Reply Obj. 3: The perfection of the way is not perfection simply, wherefore it can always increase. _______________________ NINTH ARTICLE [II-II, Q. 24, Art. 9] Whether Charity Is Rightly Distinguished into Three Degrees, Beginning, Progress, and Perfection? Objection 1: It would seem unfitting to distinguish three degrees of charity, beginning, progress, and perfection.” source
