Historically such disloyalty, synchronizing with the expansion of the Faith, had its appearance when some who were professedly loyal to the Báb, disobeyed His Covenant by refusing to accept Bahá’u’lláh as the expected One of the Bayan. They were urged on by a sordid ambition which brought them ignominy, oblivion and loss. Later the same condition became apparent after the ascension of Bahá’u’lláh when a few corrupt people violated His solemn Covenant by refusing to accept its Center, ‘Abdu’l-Bahá. Again, a diminishing few, urged on by vaulting ambition and an obvious desire to organize within the Cause, a group that would circle around themselves, have refused to acknowledge the station of our beloved Guardian, Shoghi Effendi, and the New World Order of administration called into being by the Will of ‘Abdu’l-Bahá.
