Upon the Universal House of Justice, in the words of the Guardian, "has been conferred the exclusive right of legislating on matters not expressly revealed in the Bahá'í Writings." Its pronouncements, which are susceptible of amendment or abrogation by the House of Justice itself, serve to supplement and apply the Law of God. Although not invested with the function of interpretation, the House of Justice is in a position to do everything necessary to establish the World Order of Bahá'u'lláh on this earth. Unity of doctrine is maintained by the existence of the authentic texts of Scripture and the voluminous interpretations of 'Abdu'l-Bahá and Shoghi Effendi, together with the absolute prohibition against anyone propounding "authoritative" or "inspired" interpretations or usurping the function of Guardian. Unity of administration is assured by the authority of the Universal House of Justice.
