In accordance with
the explicit text of the Kitáb-i-Aqdas Bahá'u'lláh hath made the Center of the
Covenant the Interpreter of His Word - a Covenant so firm and mighty that from
the beginning of time until the present day no religious Dispensation hath
produced its like.
- 'Abdu'l-Bahá (Cited by Shoghi Effendi in "The World Order
of Bahá'u'lláh - Selected Letters The Compilation of Compilations, vol. I, The
Covenant)
