The Process Church of the Final Judgment was the apocalyptic shadow side of the flower-powered ’60s and perhaps the most notorious cult of modern times.

Hundreds of black-cloaked devotees, often wearing a satanic “Goat of Mendes” and a swastika-like mandala, swept the streets of London, New York, Boston, Chicago, New Orleans, and Toronto, selling magazines and books with titles like Fear and Humanity is the Devil. And within the group’s “Chapters,” members would participate in “Midnight Meditations” beneath photographs of the Christ-like leader.

Celebrities like Marianne Faithful, James Coburn, and Mick Jagger participated in Process publications, and Funkadelic, in its Maggot Brain album, reprinted Process’s “Fear Issue.”

Process’s “Death Issue” interviewed the freshly imprisoned Charles Manson, leading to conspiracy hysteria in such books as Ed Sanders’s The Family and Maury Terry’s The Ultimate Evil. A lawsuit against Sanders’s Manson book led to the removal of its Process-themed chapter by Dutton.

Love, Sex, Fear, Death is the shocking, surprising, and secretive inside story of The Process Church, which was later transformed into Foundation Faith of the Millennium, and most recently as the Utah-based animal sanctuary, Best Friends.

Included will be text by Timothy Wyllie, a formative member of the Process and Foundation Faith organizations; interviews with other former Processeans; rare reproductions of Process magazines; never-before-seen photographs; and fascinating transcripts from holy books and legal actions.
