Moses Hull was once a minister in his own right. Having lost faith, he joined the burgeoning spiritualist movement of the late 1800s and began preaching against the evils of the christian body. Pointing to many (sometimes humorous) anecdotes and tales of church oppression, Hull here ruminates on the superiority of Satan over god, the superiority of occult wisdom over the barbaric nature of the christian cult, and the wonders of then-modern scientific reality, so long spurned christians. It may be seen as part demonology, part Luciferian manifesto, and part philosophical counterpoint to the greed and envy of the christian movement.
