THE MIRACLE OF ALEISTER CROWLEY’S GNOSTIC MASS Liber XV, The Mass of the Gnostic Catholic Church, is the ritualised enactment of the O.T.O.'s supreme magical secret - a technique of great potential and efficacy which is held sacred and secret by members of the Sovereign Sanctuary of the Gnosis whose duty it is to incorporate and apply the secret to their magical lives and for the benefit of humanity. Celebration of the Gnostic Mass also serves to bring the Thelemic community together to affirm a common creed, and provide an opportunity for all to participate directly in the magical formulae of the New Aeon. However, in order for all to participate directly in the magical formulae of the Mass, the ceremony must be conducted in such a manner as to be a faithful representation of the Supreme Secret - and it takes only a slight change of focus on the part of the ritual team or congregation to neutralise that formulae, and degenerate the Mass from a ceremony of the religion of the future to a ritual that merely exalts the spiritual formulae of the past. Join Archbishop Lon Milo DuQuette as he examines the nature of the Supreme Secret and helps explain the Mass in light of the Secret instead of trying to make you guess the Secret in light of the Mass. You may be very surprised by what you hear.
