Saints of Ecclesia Gnostica Catholica
The Gnostic Saints of Ecclesia Gnostica Catholica are a series of historical and mythological figures commemorated within the current of Thelema. They were first listed in Liber XV, the Gnostic Mass, which is the central rite of Ordo Templi Orientis and its ecclesiastical arm, Ecclesia Gnostica Catholica. They are found in the fifth Collect of Liber XV, titled "The Saints."
Tau Apiryon, current Primate of EGC within the U.S.A., states that:
"The Fifth Collect in Part V of Liber XV, the Gnostic Mass, defines the Saints as those who have adored the "Lord of Life and Joy," which is "the might of man" and "the essence of every true god that is upon the surface of the Earth," and who have manifested the glory of this Lord/might/essence unto men."
In the Catholic and Orthodox churches, a saint is a person who has been canonized (officially recognized) after his or her death. In Ecclesia Gnostica Catholica, death is also usually, though not necessarily, a prerequisite for sainthood, since Aleister Crowley was certainly alive when he wrote Liber XV and included himself in the list.
All of the Saints listed in the Gnostic Mass are male, and during the Collect they are invoked by the words:
"May their Essence be here present, potent, puissant and paternal to perfect this feast!"
This has been interpreted by contemporary commentators to mean that "the invocation of the Saints of Liber XV was intended to inform the office of the Priest in his role as a male adorant of the Priestess in her role as Goddess incarnate."
 Modern additions
The list of Saints in Liber XV remained static from the original writing in 1913 until relatively recently. However because the original list contains the names of four previous Patriarchs of EGC, Gerard Encausse, Carl Kellner, Theodor Reuss and Aleister Crowley, this has now been taken as a precedent for the addition of the names of succeeding Patriarchs, Karl Germer and Grady McMurtry.
The current Patriarch of EGC, Hymenaeus Beta, has exercised his authority to canonise further Gnostic Saints, and two have been officially added to the original list. William Blake was so recognized in Fall 1997 e.v. based on Crowley's essay "William Blake," which described him as such. Giordano Bruno was added to the list on February 17, 2000 e.v., the 400th anniversary of his martyrdom.
The current official version of the Collect is included below. It includes names in italics which are to be commemorated in ordinary masses, whereas the entire list is intoned for a "celebratory mass," such as when it is performed in conjunction with a Wedding.
