Chapter 19 — Part II: The Sacraments — Penance
Section 70. Detestation Of Sin — We must, then, in the first place, detest and deplore all out sins. If our sorrow and detestation extend only to some sins, our repentance is not salutary, but feigned and false. Whosoever shall keep the whole law, says St. James, but offend in one point, is become guilty of all.
