Question: What books do you recommend a new Satanist read? What’s the definitive book?
When it comes to theistic Satanism, there’s no definitive book on the subject because Satanism has always been a highly individualistic religion. There are no holy texts or origin stories that are universally accepted by all theistic Satanists. The beliefs and practices of Satanists very widely from individual to individual and group to group. The best thing you can do is study everything you can get your hands on, and choose the approach that suits you best.
Here are some recommendations that may help you:
The Black Arts by Richard Cavendish
The History of Witchcraft and Demonology by Montague Summers
The Dictionary of Demons by Michelle Belanger
Pacts with the Devil by Jason Black and Christopher Hyatt
