Chapter 19 — Part II: The Sacraments — Penance
Section 116. The Usual Minister — We now come to treat of the minister of this Sacrament. That the minister of the Sacrament of Penance must be a priest possessing ordinary or delegated jurisdiction the laws of the Church sufficiently declare. Whoever discharges this sacred function must be invested not only with the power of orders, but also with that of jurisdiction. Of this ministry we have an illustrious proof in these words of our Lord, recorded by St. John: Whose sins you shall forgive, they are forgiven them; and whose sins you shall retain, they are retained, words addressed not to all, but to the Apostles only, to whom, in this function of the ministry, priests succeed.
