Although the Church of Satan does not have an official language, the church's authoritative text, "The Satanic Bible," contains sections written in English and Enochian. Enochian is a language created in the 16th century by John Dee and Edward Kelly.
Dee and Kelly claimed that the Enochian language was revealed to them by angels. The language is commonly found in occult and satanic teachings.
"The Satanic Bible" is mostly written in English, but it includes a section known as the "Enochian Keys." This portion is then translated into English. The Church of Satan focuses on the rhythmic delivery of these words rather than a precisely correct pronunciation.
