Samael Aun Weor, born Víctor Manuel Gómez Rodríguez, was an author, lecturer and founder of the Universal Christian Gnostic Movement. His teaching of 'The Doctrine of Synthesis' of all religions in both their esoteric and exoteric aspects has been called neo-Gnostic by the historian of esotericism Arthur Versluis and called by the historian Jean-François Mayer "a science of consciousness or knowledge that may be attained through certain techniques." In his over sixty books and hundreds of held conferences, he describes a teaching called "gnosis", the Greek word for "knowledge", from which is derived the name "Gnosticism".
