Chapter 16 — Part II: The Sacraments — Baptism
Section 84. Hence, to the vast multitude who, in compunction of heart, as the Scripture says, asked him and the other Apostles what they should do, the Prince of the Apostles answered: Do penance and be baptised every one of you; and in another place he said: Be penitent, therefore, and be converted, that your sins may be blotted out. Writing to the Romans, St. Paul also clearly shows that he who is baptised should entirely die to sin; and he therefore admonishes us not to yield our members as instruments of iniquity unto sin, but present ourselves to God, as those who are alive from the dead.
