A glance at the writings of the Author of the Bahá’í Revelation will reveal the important and significant fact that He [Baha’u’llah] Who addressed collectively an immortal message to all the kings of the earth, Who revealed a Tablet to each of the outstanding crowned heads of Europe and Asia, Who issued His call to the sacerdotal leaders of Islám, both Sunní and Shí’ih, Who did not exclude from His purview the Jews and the Zoroastrians, has, apart from His numerous and repeated exhortations and warnings to the entire Christian world, directed particular messages, some general, others precise and challenging, to the heads, as well as to the rank and file, of the ecclesiastical orders of Christendom—its pope, its kings, its patriarchs, its archbishops, its bishops, its priests, and its monks.
