The Process Church of the Final Judgement was a religious organization founded by Robert and Marry Ann DeGrimston (ne Robert DeGrimston Moore and Mary Ann McClean). The group started as a splinter cult from Scientology in 1964 (as just “The Process”) and lasted until the mid 70s. The group lives on, without the DeGrimstons, as the Best Friends Animal Society.
Though somewhat forgotten today, the Process Church was well known and influential in its time. For example, legendary funk musician George Clinton included excerpts from the magazine in the liner notes for Funkadelic’s Maggot Brain and America Eats Its Young. However, they are probably best known for allegations that they influenced Charles Manson. The media attention that followed these allegations, and a split between the DeGrimstons, lead the Church’s demise.
Although he was never a member, Genesis P. Orridge was highly influenced by the Process Church of the Final Judgement and modeled some aspects of the Temple ov Psychick Youth (TOPY), which he co-founded in 1991, after the Church. After attempting to shut down the Temple in 1991, Orridge co-founded a collective variously called The Process, TOPI (either not an acronym, or “Thee Outer Process International”) or Transmedia Foundation. This new group spawned a mailing list and website called “The Process.” By 1998 Orridge and co-founder Ogre of Skinny Puppy had turned the mailing list and site over to the community and were no longer actively involved. The site and list continue to exist albeit quietly. Orridge started a new group called “One True TOPI Tribe” in 2010.
