Chapter 20 — Part II: The Sacraments — Extreme Unction
Section 32. Pastors, therefore, should teach that by this Sacrament is imparted grace that remits sins, and especially lighter, or as they are commonly called, venial sins; for mortal sins are removed by the Sacrament of Penance. Extreme Unction was not instituted primarily for the remission of grave offences; only Baptism and Penance accomplish this directly.
