(μυσταγωγία , introduction to the mysteries) is a term used in the early Christian churches of the Orient to designate either the Lord's Supper or baptism. To designate the former it is frequently found in the writings of Cyril of Jerusalem and of Theodoret. It was intimately connected with the secret discipline, but fell into disuse with the termination of that system. See Riddle, Christian Antiquities, pages 485, 547; Bingham, Antiq. of the Christian Church (see Index). (See MYSTAGOGUE).
