Ecclesia Gnostica Catholica (E.G.C.), or the Gnostic Catholic Church (the Church), is the ecclesiastical aspect of Ordo Templi Orientis (O.T.O.). The E.G.C. is a Thelemic religious environment, dedicated to the advancement of Light, Life, Love, and Liberty through alignment with the Law of Thelema. The central activity of the E.G.C. is the celebration of the Gnostic Mass, as set forth in Liber XV, composed by Crowley for O.T.O. and E.G.C. in 1913. Lay membership in E.G.C. is available through baptism and confirmation. Members of O.T.O. in good standing are eligible for clerical ordination in E.G.C. Members of II° and higher (or even I°, in some situations) are eligible for ordination as Deacon, and those who have reached K.E.W. are eligible for ordination as Priest or Priestess. Many O.T.O. local bodies celebrate the Gnostic Mass on a regular basis, and in most locations, no formal affiliation is required to attend the Mass.
