Sacrament
Sacrament, and name signifying the Roman military oath, and used in the Vulgate as equivalent to the Greek mysterion, hence its adoption as the name of the symbolical religious ceremony. The Church defines a Sacrament as an "outward visible sign of an inward spiritual grace" imparted. The Greek and Roman Churches have seven Sacraments - Baptism, Confirmation, the Eucharist, Penance, Orders, Marriage, and Extreme Unction. Of these the English Church holds only the first and third to be sacraments in the full sense.
