Catechesis: Repentance

This repentance endures among Christians until death because it struggles with the sin that remains in the flesh throughout life. As St. Paul bears witness in Romans 7[:23], he wars with the law in his members, etc.—not by using his own powers but by the gift of the Holy Spirit which follows from the forgiveness of sins. This same gift daily cleanses and sweeps away the sins that remain and works to make people truly pure and holy.—SA III:III:40
