Extreme Unction, also known as the Sacrament of the Anointing of the Sick, is a practice in the Christian faith where a priest anoints a seriously ill or dying person with holy oil. This sacrament is intended to provide spiritual strength, healing, and comfort to the individual, helping them to face their illness or impending death. The anointing typically involves prayers and the application of oil on the forehead and hands of the recipient. It is based on the teachings found in the New Testament, specifically in the book of James, which encourages the faithful to seek healing through prayer and anointing.
