1844-1944: Gradation in the character of the opposition the Baha’i Faith had to encounter

…gradation in the character of the opposition it has had to encounter—an opposition, at first kindled in the bosom of Shí’ah Islám, which, at a later stage, gathered momentum with the banishment of Bahá’u’lláh to the domains of the Turkish Sultán and the consequent hostility of the more powerful Sunní hierarchy and its Caliph, the head of the vast majority of the followers of Muhammad—an opposition which, now, through the rise of a divinely appointed Order in the Christian West, and its initial impact on civil and ecclesiastical institutions, bids fair to include among its supporters established governments and systems associated with the most ancient, the most deeply entrenched sacerdotal hierarchies in Christendom.
