Quoted in the book of Jude, and used to form our view of angels and demons, this book connects the dots of doctrine and prophecy in the scriptures. Details are revealed about the “Sons of God (Angels) that left their positions in heaven to marry human women”, having children that became giants and monsters called Nephilim who introduced violence, sorcery, and evil spirits into the world. This book, along with the Book of Jubilees, is considered sacred to the Christian church in Ethiopia and is placed in their Bible along side the Old Testament books.
