Chapter 19 — Part I — Unction
Section 365. Q. Whence is the origin of this Sacrament? A. From the Apostles, who, having received power from Jesus Christ, anointed with oil many that were sick, and healed them. Mark vi. 13. The Apostles left this Sacrament to the priests of the Church, as is evident from the following words of the Apostle James: Is any sick among you? let him call for the elders of the Church; and let them pray over him, anointing him with oil in the name of the Lord; and the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him. James v. 14, 16.
