"a world commonwealth in which all nations, races, creeds and classes are closely and permanently united…a world legislature whose members will…ultimately control the entire resources of all the component nations…A world executive, backed by an international Force…A world tribunal…A mechanism of world inter-communication…A world metropolis will act as the nerve center of a world civilization….A world language will either be invented or chosen from among the existing languages…A world script, a world literature…currency…weights and measures…A world federal system, ruling the whole earth and exercising unchallengeable authority over its unimaginably vast resources"
- Shoghi Effendi quoted in The Bahá'is, A Profile of the Bahá'i Faith and its Worldwide Community (Oakham, Leicestershire, UK: Bahá'í International Community, 1994), p. 75
