Master Jesus is the theosophical concept of Jesus in Theosophy and the Ascended Master Teachings.
The Master Jesus is one of the Masters of the Ancient Wisdom in Theosophy and is one of the Ascended Masters (also collectively called the Great White Brotherhood; with white being in reference to the light) in the Ascended Master Teachings, a group of religions based on Theosophy. The Master Jesus is regarded by Theosophists, was regarded by Alice Bailey and was later regarded by students of the "Ascended Master Teachings" as the Master of the Sixth Ray.
It is believed by Ascended Master Teachings organizations that the Master Jesus was "Chohan of the Sixth Ray" until December 31, 1959, when, according to Elizabeth Clare Prophet, Lady Master Nada fully took on that Office in the Spiritual Hierarchy. According to Prophet, Jesus became World Teacher, along with Kuthumi, on January 1, 1956, succeeding Maitreya, who took the Office of "Planetary Buddha" and "Cosmic Christ". This belief is not accepted by adherents of traditional Theosophy and the followers of Alice A. Bailey and Benjamin Creme; they believe that the Master Jesus is still the Chohan of the Sixth Ray and that Maitreya is still the World Teacher.
According to Elizabeth Clare Prophet, the Prophet of the Church Universal and Triumphant, the largest Ascended Master Teachings religion, the Master Jesus incarnated twice as the Emperor of Atlantis, once in 33,050 BC and again in 15,000 BC. He did this in order to aid the white magicians in the war of the white magicians and the black magicians that was going on in Atlantis at that time.
