We witness a corresponding increase in the diversity of the
elements within its fellowship, which from being confined, in the first period
of its history, to an obscure body of followers chiefly recruited from the
ranks of the masses in Shi‘ah Persia, has expanded into a fraternity
representative of the leading religious systems of the world, of almost every
caste and color, from the humblest worker and peasant to royalty itself.
- Shoghi Effendi (‘Preface to God Passes By’)
