The oil of the sick is mentioned in the well-known passage of St. James V, 14 "Is any man sick among you; let him bring in the priests of the church, and let them pray over him, anointing him with oil in the name of the Lord etc." At the beginning of the fifth century also, Pope Innocent I observes that it is the office of the bishop to make or prepare (_conficere_) this "holy of chrism" or unction: and in the Sacramentary of Pope Gregory the great the rite; by which this oil was blessed and administered to the sick, is described. Chrism and the oil of catechumens also are mentioned by many ancient Fathers. (See Turnely T. 7 de Sacram. Bapt. et Confirm, etc.)[61] St. Basil in the 4th century attributes the origin of the custom of blessing the oils to tradition. "We bless the water of baptism and the _oil of unction_, as well as the person who receives baptism. By what scriptures? Is it not from silent and secret tradition?" (De Spir. S. c. 27). It is mentioned also in the second and third councils of Carthage, by S. Cyprian, who says "The eucharist, and the oil, with which the baptised are anointed, are sanctified at the altar". Ep. 70. It would appear however from the 20th canon of the first council of Toledo that anciently chrism could be blessed _at any time_; and hence Benedict XIV is of opinion, that the custom of blessing it only on holy Thursday began about the seventh century; for it is mentioned in the Sacramentary of S. Gregory, in the old Ordo Romanus, and in other works written after that period. This day has been with reason chosen for this ceremony, as St. Thomas observes, in order that the chrism may be prepared for the solemn baptism administered on Easter Eve; and because on it the Eucharistic sacrament, for which the other sacraments are as it were preparatory, was instituted. S. Isidore however assigns a different reason, viz. that two days before the pasch Mary _anointed_ the head and feet of the Lord". De Divi Off. lib. 2, c. 28.
