Catechism of the Catholic Church

However, the apostolic Church has its own rite for the sick, attested to by St. James: "Is any among you sick? Let him call for the elders [presbyters] 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 man, and the Lord will raise him up; and if he has committed sins, he will be forgiven." Tradition has recognized in this rite one of the seven sacraments. (1117)
