There are three types of churches: first, the Triumphant Church, represented by the few Knights of the Grail who persisted to remain pure; second, the Failing Church, represented by those who abhor the Initiatic Stone; third, the Militant Church, represented by the others, who as Mary Magdalene, Paul of Tarsus, Kundry, and Amfortas, are still in rebellion against the seductive Luciferic fire. - Samael Aun Weor, Magic of the Runes
Those who did not directly receive the mysteries of the stone constituted the failing church, which broke away from the Gnostic Christic Esotericism as a result of literally interpreting scripture, lacking genuine initiation into the greater mysteries, and psychological degeneration.
