The first four books of the Christian New Testament: Matthew, Mark, Luke, and John.
“The four Gospels can only be understood with the key of Sexual Magic and the Perfect Matrimony. The four Gospels were only written to serve as a guide to the few who follow the Path of the Razor’s Edge. The four Gospels were never written for the multitudes.” - Samael Aun Weor, The Perfect Matrimony
