EGC

Ecclesia Gnostica Catholica (E.G.C.), or the Gnostic Catholic Church, is the ecclesiastical arm 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, written by Aleister 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 are eligible for ordination as Deacon, and those who have reached K.E.W. are eligible for ordination as Priest, Priestess, or Deacon-Sacerdote. Many O.T.O. local bodies celebrate the Gnostic Mass on a regular basis. In most locations, no formal affiliation is required to attend the Mass.
