Ecclesia Gnostica Catholica (E.G.C.), also known as the Gnostic Catholic Church, serves as the ecclesiastical branch of Ordo Templi Orientis (O.T.O.). Within the E.G.C., individuals embrace the principles of Thelema, dedicating themselves to the pursuit of Light, Life, Love, and Liberty in alignment with the Law of Thelema.

At the core of the E.G.C. is the celebration of Liber XV: The Gnostic Mass, a profound ritual authored by Aleister Crowley specifically for O.T.O. and E.G.C. in 1913. Lay membership in the E.G.C. is accessible through the rites of baptism and confirmation, though welcome guests of the Order may regularly attend Gnostic Mass celebrations without formal affiliation.
