Chapter 19 — Part II: The Sacraments — Penance
Section 152. But with regard to public sinners, as we have already said, they were never absolved until they had performed public penance. During the performance of this penance, the pastors poured out prayers to God for their salvation, and ceased not to exhort the penitents to do the same. In this respect, great was the care and solicitude of St. Ambrose, of whom it is related that many who came to the tribunal of Penance with hardened hearts were so softened by his tears as to conceive the sorrow of true contrition. But in process of time the severity of ancient discipline was so relaxed and charity grew so cold, that in our days many of the faithful think inward sorrow of soul and grief of heart unnecessary for obtaining pardon, imagining that a mere appearance of sorrow is sufficient.
