Chapter 19 — Part II: The Sacraments — Penance

Section 1. Importance Of Instruction On This Sacrament — As the frailty and weakness of human nature are universally known and felt by each one in himself, no one can be ignorant of the great necessity of the Sacrament of Penance. If, there- fore, the diligence of pastors should be proportioned to the weight and importance of the subject, we must admit that in expounding this Sacrament they can never be sufficiently diligent. Nay, it should be explained with more care than Baptism. Baptism is administered but once, and cannot be repeated; Penance may be administered and becomes necessary, as often as we may have sinned after Baptism. Hence the Council of Trent declares: For those who fall into sin after Baptism the Sacrament of Penance is as necessary to salvation as is Baptism for those who have not been already baptised. The saying of St. Jerome that Penance is a second plank, is universally known and highly commended by all subsequent writers on sacred things. As he who suffers shipwreck has no hope of safety, unless, perchance, he seize on some plank from the wreck, so he that suffers the shipwreck of baptismal innocence, unless he cling to the saving plank of Penance, has doubtless lost all hope of salvation.
