Universal House of Justice and the world’s future super-state

...recognition of the Faith of Bahá’u’lláh, not merely as one of the recognized religious systems of the world, but as the State Religion of an independent and Sovereign Power. ...will the Universal House of Justice attain the plenitude of its power, and exercise, as the supreme organ of the Bahá’í Commonwealth, all the rights, the duties, and responsibilities incumbent upon the world’s future super-state. 

- Shoghi Effendi
