Google 'The Process Church of the Final Judgement' and you'll discover a long list of conspiracy theories. Only now, former members reveal the truth about the misunderstood group once dubbed 'One of the most dangerous Satanic cults in America.'

This is a video performance of their holiest ritual, the Sabbath Assembly, as recorded August 23, 2009 at The Silent Movie Theater in Los Angeles CA. About 50% of the video is the ritual itself, consisting of recitations from their unique liturgy interspersed with vintage hymns. The text is read by original Process minister Sammy M Nasr and the songs are performed here by the band Sabbath Assembly (Jex Thoth, Imaad Wasif, Kevin Rutmanis and Dave Nuss - obviously taking their name from the ceremony itself). Following the ritual is a slideshow presentation on the church narrated by original Process member/author Timothy Wyllie and finally a Q&A interview with Timothy conducted by Feral House publisher Adam Parfrey. So while it's not a documentary exactly, you certainly learn about the history of the church, its practices, and get a good feel of what it was like to be a member.
