The Process, or in full, The Process Church of the Final Judgment, commonly known by non-members as the Process Church, was a religious group that flourished in the 1960s and 1970s, founded by the English couple Mary Anne and Robert DeGrimston (originally Robert Moor and Mary Anne MacLean).Originally headquartered in London, it had developed as a splinter group from Scientology,so that they were declared “suppressive persons” by L. Ron Hubbard in December 1965. In 1966, members of the group underwent a social implosion and moved to Xtul on Mexico’s Yucatan peninsula, where they developed “processean” theology (which differs from, and is unrelated to process theology). They later established a base of operations in the United States in New Orleans.
They were often viewed as Satanic on the grounds that they worshipped both Christ and Satan. Their belief was that Satan would become reconciled to Christ, and they would come together at the end of the world to judge humanity, Christ to judge and Satan to execute judgment.
