"Irregular" that might be better suited, briarfriar. :clap:
The OTO was a quasi-Masonic fraternity, not recognized as such by the UGLE, before Crowley became its head. It's purpose was to still be a Masonic body even after Crowley took over. Never was it supposed to be a Magical System nor Society, but ethical. It's secrets were sexual in nature and still remained sexual after Crowley took reign. The rituals were rewritten, quite beautifully actually, and were romantically Templar in origin. Crowley did a damn good job. Was Crowley a Freemason? Yes. Was Crowley Raised in a "Regular" Lodge? I don't know and probably will never find out. If Crowley did not have command of his Masonic Knowlege, I believe Theodor Reuss would have thrown Crowley out by the bow tie if he suspected a Cowan. Reuss was involved in many different Masonic Bodies at the Founding of the OTO and before. Quite an interesting subject of research for Masons and Non-Mason's alike.
Side note: the magical formula of Crowley's Thelema was 93. The Substitue equals 93 by use of the English Qabalah. I doubt very seriously that the Current KnumSkulls of the OTO have discovered this Intriging secret. Perhaps Crowley did bring in the new Aeon. :wink:
