The Sacraments

‘The word sacrament is not found in the Bible, but arose in the course of the early history of the church. It comes from the Latin sacramentum, which signified an oath or pledge which a soldier took at enlisting, and was also used to denote the flag, ensign or badge of battle. The term shows affinity to the ideas of initiation and warfare.
