Unto the Most Holy Book every one must turn and all that is not expressly recorded therein must be referred to the Universal House of Justice. That which this body, whether unanimously or by a majority doth carry, that is verily the Truth and the Purpose of God Himself.  (‘Abdu’l-Baha, ‘The Will and Testament of 'Abdu'l-Bahá’; The Compilation of Compilations, vol. I, The Covenant)
