Oil obtained from the pulp of olives. It is mixed with balsam in the making of chrism, which is used in the administration of certain sacraments. It represents the copious outpouring of sacramental grace which gives strength to the soul as oil does to the body. In the Old Testament God commanded that a lamp filled with purest oil of olives should always burn in the Tabernacle of the Testimony (Exodus 27); it was also used in many religious ceremonies, e.g., coronation of kings, consecration of the high priest, and ordination of the Levites, and was prominent in Mosaic ordinances (Exodus 30; Leviticus 8; Deuteronomy 28).
