The Gnostic Mass is the central religious ritual of the O.T.O. and its church, Ecclesia Gnostica Catholica (E.G.C), written by Aleister Crowley to express Thelema's philosophy as a modern spirituality, blending scientific truth with religious aspiration through symbolic ceremony involving Priest, Priestess and Deacon. It is intended as a modern, non-dogmatic spiritual experience celebrating reality emphasizing individual spiritual freedom and joy culminating in the words "There is no part of me that is not of the gods!"Do what thou wilt shall be the whole of the law. Love is the Law, Love under Will.
