For those (few) of you who are interested there was a book published recently "Love, Sex, Fear, Death: The Inside Story of The Process Church of the Final Judgment" by Timothy Wyllie (Editor) and Adam Parfrey.
It's an intriguing account of life inside a cult and includes lots of original material published by the Church. One account that intrigued me was one chap who was ostracized by the group for a period and ordered to expiate his faults. He took to flagellating himself and found that it induced a transcendental mystical state in which he left his body and experienced a state of ecstasy. When he returned to live with the other members he reported his experiences and many followed his example and experienced the same heightened state. When we read of medieval self-flagellants we naturally assume it's a perverse phenomenon induced by morbid guilt. But was it a masochistic indulgence or could it be that they too were experiencing that ecstatic release and were actually "enjoying" themselves? https://www.youtube.com/watch?v=VGJ7yZRW8bg&list=PLPA9OHUL1rGFZqLDHHHLS_oOtfF9DRuID&index=3 https://www.youtube.com/watch?v=VGJ7yZRW8bg&list=PLPA9OHUL1rGFZqLDHHHLS_oOtfF9DRuID&index=3
