Chapter 19 — Part II: The Sacraments — Penance
Section 85. According to the doctrine of the Catholic Church, a doctrine firmly to be believed and constantly professed by all, if the sinner have a sincere sorrow for his sins and a firm resolution of avoiding them in future, although he bring not with him that contrition which may be sufficient of itself to obtain pardon, all his sins are forgiven and remitted through the power of the keys, when he confesses them properly to the priest. Justly, then, do those most holy men, our Fathers, proclaim that by the keys of the Church the gate of heaven is thrown open, a truth which no one can doubt since the Council of Florence has decreed that the effect of Penance is absolution from sin.
