The Kitáb-i-Aqdas - The Most Holy Book
Index term: Succession
any reference to Viceregency debar you from the sovereignty of Him Who is the Viceregent of God
The word here translated "Vicegerency" is, in the original Arabic, "vilayát", which has a range of meanings including "vicegerency", "guardianship", "protectorship" and "successorship". It is used in relation to God Himself, to His Manifestation, or to those who are the appointed Successors of a Manifestation.
In this verse of the Aqdas, Bahá'u'lláh warns against allowing such concepts to blind one to the "sovereignty" of the new Divine Manifestation, the true "Vicegerent of God".
