Will and Testament — Paragraph 58

For he is, after ‘Abdu’l‑Bahá, the Guardian of the Cause of God; the Afnán, the Hands (pillars) of the Cause of God and the beloved of the Lord must obey him and turn unto him. He that obeyeth him not, hath not obeyed God; he that turneth away from him, hath turned away from God and he that denieth him, hath denied the True One. Beware lest anyone falsely interpret these words, and like unto them that have broken the Covenant after the Day of Ascension (of Bahá’u’lláh) advance a pretext, raise the standard of revolt, wax stubborn and open wide the door of false interpretation. To none is given the right to put forth his own opinion or express his particular conviction. All must seek guidance and turn unto the Centre of the Cause and the House of Justice. And he that turneth unto whatsoever else is indeed in grievous error.
