The principle of the Oneness of Mankind, as proclaimed by
Bahá'u'lláh, carries with it no more and no less than a solemn assertion that
attainment to this final stage in this stupendous evolution is not only
necessary but inevitable, that its realization is fast approaching, and that
nothing short of a power that is born of God can succeed in establishing it.
- Shoghi Effendi (From a message dated 28 November 1931, published in ‘The World Order of Bahá'u'lláh’; The
Compilation of Compilations, Vol.III, Cultural Diversity in the Age of Maturity)
