Orphan Utopia: John Ballou Newbrough’s desert colony (2017)

The twelve adherents of Faithism, perhaps the smallest religion in the world, hold weekly prayer meetings on Skype to study their holy book, Oahspe, dictated by angels in 1881 to a New York dentist called John Ballou Newbrough. Newbrough’s first followers set up a vegetarian commune in New Mexico to raise 10,000 orphaned babies, but collected only 28.

The Wikipedia page is suprisingly detailed: https://en.wikipedia.org/wiki/Oahspe:_A_New_Bible and includes interesting links like
