From Satan to Shelter Dogs — The Process Church

The Fires of History — Episode 56

A Scientology splinter group worships four gods including Satan from a Mayfair townhouse. Three decades later it is the largest no-kill animal rescue in the United States. The container survived. The contents were swapped one at a time, the way you replace ship planks at sea. The dogs got a good deal out of it.

The Scientology Connection

Robert de Grimston and Mary Ann MacLean met inside Scientology. This is not incidental. It is the origin story.

De Grimston was upper-class British — Army officer, architecture student at the Architectural Association in London. MacLean grew up in poverty in Glasgow and is documented as having worked as a high-end prostitute servicing British business and political figures before finding Scientology. The class gulf between them was significant. The shared experience of Scientology bridged it.

Both were declared “Suppressive Persons” by L. Ron Hubbard in 1965 — Scientology’s formal designation for enemies of the organization. Expulsion from Scientology is not a minor biographical footnote. It means the organization’s internal security apparatus identified you as a threat. What de Grimston and MacLean took with them when they left was not resentment but methodology. They understood how to build a high-commitment group. They understood the techniques of auditing, confessional practice, and hierarchical control. They had been inside the machine and seen how it worked.

They built their own.

Compulsions Analysis

The first iteration was called Compulsions Analysis — a therapy practice using modified Scientology techniques. It operated from London and attracted clients through word of mouth. The step from therapy group to religious movement was gradual and, in retrospect, inevitable. Every therapy practice that develops its own cosmology is a religion waiting to incorporate. Compulsions Analysis developed its own cosmology faster than most.

By 1966, the group had formalized as the Process Church of the Final Judgment. The name was not chosen for subtlety.

The Theology

The Process Church’s theological system was baroque. The church recognized four deities: Jehovah, Lucifer, Satan, and Christ. Not metaphors. Not archetypes in a Jungian sense. Four actual gods, each representing a fundamental aspect of existence, each demanding acknowledgment and worship. The theology was neo-Gnostic — a synthesis of Scientology-derived psychological techniques, occult ritual, and a cosmological framework that owed more to Aleister Crowley than to any mainstream religious tradition.

Members wore distinctive black robes. The church published a magazine called The Process with production values that belied its membership numbers — glossy, professionally designed, and containing material that ranged from theological essays to content that would have been disturbing in any context and was considerably more disturbing coming from people in black robes who worshipped Satan alongside three other deities.

The first commune was at 2 Balfour Place, Mayfair — one of the wealthiest neighborhoods in London. A Satanic church operating from a Mayfair townhouse is exactly the kind of detail that sounds invented but is not.

The Manson Connection

In 1971, Ed Sanders published The Family, an account of the Manson murders. The book alleged connections between Charles Manson and the Process Church. The Process Church sued. The references were removed from subsequent editions.

The allegation was later revived and expanded by Maury Terry in The Ultimate Evil (1987), which claimed connections between the Process Church, Manson, and the Son of Sam killings. These allegations have been extensively investigated by scholars and journalists and are generally regarded as unsubstantiated. “Generally regarded as unsubstantiated” is academic language for “this falls apart under scrutiny but will never fully go away because it is too interesting to abandon.”

The Manson connection matters not because it is true but because it demonstrates the gravitational pull of conspiracy narrative. A small religious group that worships Satan, wears black robes, and publishes disturbing content will inevitably attract allegations of connection to any high-profile crime that involves Satanic themes. The allegation does not require evidence. It requires adjacency.

The Schism

In 1974, Mary Ann MacLean expelled Robert de Grimston from the organization he had co-founded. The details of the split are contested, but the outcome is not: MacLean took control of the remaining membership, and de Grimston was out. He lived quietly afterward, dying in 2014 without ever returning to public religious life.

This is the pivot point. Everything before 1974 is the Process Church. Everything after is something else.

The Transformation

What followed was the most complete organizational metamorphosis in modern religious history. It happened in stages, and the stages are themselves the argument.

• 1974: Foundation Church of the Millennium. Satan dropped from the pantheon.
• 1977: Foundation Faith of the Millennium. Further theological simplification.
• 1980: Foundation Faith of God. The remaining cosmology stripped back to something approaching mainstream monotheism.
• 1993: Best Friends Animal Society. All reference to religious ideas removed from the organization’s statutes.

The geographic migration tracked the theological one: England to Florida (1970), Florida to Arizona (1978), Arizona to Kanab, Utah (1984). Each move took the group further from its origins — geographically, theologically, and institutionally.

Best Friends Today

Best Friends Animal Society is now one of the largest no-kill animal rescue organizations in the United States. It operates the nation’s largest sanctuary for companion animals in Kanab, Utah. Its website describes its founders as friends on a spiritual quest who grew tired “of complicated cosmologies that added nothing to the preferred simplicity of a life based on service and the Universal Law.”

This is technically accurate the way describing the French Revolution as “a period of political change” is technically accurate. The “complicated cosmologies” included four simultaneous deities, one of whom was Satan. The “spiritual quest” began in the wreckage of Scientology and passed through a decade of occult practice, black robes, and a magazine that would not have been out of place at a Crowley reading group. The journey from there to shelter dogs is real. The sanitized version of the journey is also real. Both versions are doing work.

They dropped Satan. They dropped Lucifer. They dropped Jehovah. They kept the animals. Whatever else you can say about the Process Church’s theological trajectory, the dogs got a good deal out of it.

The Key Figures

Robert de Grimston (1935–2014). Born Robert Moor. Upper-class English background, Army service, architecture student. Co-founded the Process Church, served as its public face and primary theologian. Expelled by MacLean in 1974. Lived quietly for forty years. His post-Process life is almost completely undocumented, which is either the sign of a man who found peace or a man who found a very good privacy strategy.

Mary Ann MacLean (1931–2005). Born in Glasgow. Documented history of poverty and sex work before Scientology. Co-founded the Process Church, expelled de Grimston, and guided the organization through its thirty-year transformation from Satanic church to animal rescue. The organizational skill required to execute that transformation — to hold a group together through five name changes, four theological overhauls, and a complete identity reset — is genuinely remarkable regardless of what you think of the starting point.

Why This Matters

The Process Church is not a trolling story. It is a transformation story, and the transformation is the argument. The thesis of Hidden Fire is that heretical and transgressive movements do not always burn out or get destroyed. Sometimes they mutate. Sometimes the mutation is so complete that the original form becomes unrecognizable.

The Process Church → Best Friends pipeline is the most extreme case. A Satanic church became an animal rescue. The mechanism is not mysterious: a high-commitment group with strong internal bonds, led by a charismatic organizer, gradually shed the elements that made it dangerous or marginal and retained the elements that made it functional — community, shared purpose, institutional structure. The content changed completely. The container survived.

MacLean’s expulsion of de Grimston is a textbook case of charismatic succession. The public founder is removed. The operational leader takes control. The organization survives because the operational infrastructure was always more important than the figurehead theology. De Grimston was the face. MacLean was the spine. This pattern recurs across every cult and new religious movement that survives its first generation. The theology is replaceable. The organizational structure is not.

Best Friends’ own account of its founding is a masterclass in institutional memory management. The founders were “friends on a spiritual quest.” True. The quest involved worshipping Satan. Also true. The omission is not a lie — it is a curatorial choice, and every institution makes the same choice about its own origins. The question is not whether the sanitized version is honest. The question is whether it matters. Best Friends has saved hundreds of thousands of animals. The dogs do not care about the Process.
