Liber XV The Gnostic Mass is the central public and private ceremony of the O.T.O. and is performed under the auspices of Ecclesia Gnostic Catholica, the Gnostic Catholic Church. A copy of the text of the ritual is available with annotations online. More details about the E.G.C. are available on the E.G.C. website.


Gnostic Masses are held regularly at many O.T.O bodies many are open all who wish to attend, by invitation; please contact your nearest local body for details.

Baptisms and Confirmations into E.G.C can often be performed at Gnostic Masses, and are also open to non-O.T.O. initiates. To be confirmed you must have been baptised into the E.G.C, have learned the Gnostic Creed, and bring a white robe with you. To take part in either of these sacraments please contact your local body of O.T.O.
