…the fate that has overtaken those kings, ministers and ecclesiastics, in the East as well as in the West, who have, at various stages of Bahá’u’lláh’s ministry, either deliberately persecuted His Cause, or have neglected to heed the warnings He had uttered, or have failed in their manifest duty to respond to His summons or to accord Him and His message the treatment they deserved, particular attention… Bahá’u’lláh Himself, referring to those who had actively arisen to destroy or harm His Faith, had declared that “God hath not blinked, nor will He ever blink His eyes at the tyranny of the oppressor. More particularly in this Revelation hath He visited each and every tyrant with His vengeance.” Vast and awful is, indeed, the spectacle which meets our eyes, as we survey the field over which the retributory winds of God have, since the inception of the ministry of Bahá’u’lláh, furiously swept, dethroning monarchs, extinguishing dynasties, uprooting ecclesiastical hierarchies, precipitating wars and revolutions, driving from office princes and ministers, dispossessing the usurper, casting down the tyrant, and chastising the wicked and the rebellious.
