Chapter 21 — Part II: The Sacraments — Holy Orders
Section 50. The Internal Priesthood — Regarding the internal priesthood, all the faithful are said to be priests, once they have been washed in the saving waters of Baptism. Especially is this name given to the just who have the Spirit of God, and who, by the help of divine grace, have been made living members of the great High-priest, Jesus Christ; for, enlightened by faith which is inflamed by charity, they offer tip spiritual sacrifices to God on the altar of their hearts. Among such sacrifices must be reckoned every good and virtuous action done for the glory of God.
