Three core principles establish a basis for Bahá'à teachings and doctrine: the unity of God, the unity of religion, and the unity of humankind.[3] From these postulates stems the belief that God periodically reveals his will through divine messengers, whose purpose is to transform the character of humankind and develop, within those who respond, moral and spiritual qualities. Religion is thus seen as orderly, unified, and progressive from age to age.
Who are these messengers? These messengers have included Abraham, Buddha, Jesus, Muhammad and others, and most recently the Báb and Bahá'u'lláh.
