More about the Bahá'í religion below.
The central theme of Bahá'u'lláh's message is that humanity is one single race and that the day has come for its unification in one global society. God, Bahá'u'lláh said, has set in motion historical forces that are breaking down traditional barriers of race, class, creed, and nation and that will, in time, give birth to a universal civilization. The principal challenge facing the peoples of the earth is to accept the fact of their oneness and to assist the processes of unification.
