The Chrism Mass is a religious service held in Roman Catholicism, Lutheranism, and Anglicanism. The Chrism Mass is one of the most solemn and important liturgies of the Christian liturgical calendar. The ancient Christian Apostolic Tradition (c. 200 A.D.) described a "ceremony taking place during the Easter Vigil at which two holy oils were blessed and one was consecrated." During this rite, two oils were "blessed by the bishop: the oil of the sick and the oil of exorcism".
