Shoghi Effendi feels that the unity of the Bahá’í
Revelation as one complete whole embracing the
Faith of
the Báb should be emphasized... The Faith of the Báb should not be divorced from that of
Bahá’u’lláh. Though the teachings of the
Bayán have been abrogated and superseded by the laws of the Aqdas, yet due to the fact that the Báb considered Himself as the Forerunner of Bahá’u’lláh, we would regard His
Dispensation together with that of Bahá’u’lláh as forming one entity, the former being introductory to the advent of the latter.
The Báb states that His laws are provisional and depend upon the acceptance of the future
Manifestation. This is why in the Book of Aqdas Bahá’u’lláh sanctions some of the laws found in the Bayán, modifies others and sets aside many.
