On Universal Life Church, look up the names Thomas Beckham and Raymond Broshears to start down a big rabbit hole. . .Historically, Universal Life Church has often acted as part of a racket involving a number of “churches” with various names where anyone can get “ordained” as a bishop and start their own religious outfit by paying a fee. Having acquired such a veneer of legitimacy, said “bishop” can mix whatever teachings they want together into an occult smorgasbord and make up whatever phony history they want to give it an appearance of authenticity. Many “bishops” in this movement used this as a cover for occult activity as well as homosexual networking. Crowley and people of similar ilk found this very useful for their purposes.
On the Seattle connection, since I’m on the topic, I’ll mention that Crowley stopped in Seattle on his tour of the U.S. during World War I, and Beckham had an associate named Fred Lee Crisman who was from Tacoma, Washington and had been involved in the occult community (via SF fandom) there since the 1940s. Charles Manson sometimes drove up to Seattle, where there was a cult similar to his called the Love Israel Family. Of course this is just scratching the surface of Seattle weirdness.
