Instituted by the Lord Jesus when He said to His disciples, “Heal the sick, cleanse the lepers” (Matthew 10:8), and, “Whatever city you enter heal the sick who are there” (Luke 10:8). The Apostles then put the Lord’s words into practice: “They anointed with oil many who were sick and healed them” (Mark 6:13). Our teacher St. James the Apostle advised believers to practice it, by saying, “Is anyone among you sick? 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 will save the sick, and the Lord will raise him up, and if he has committed sins, he will be forgiven” (James 5:14-15).
