The purpose of religion as revealed from the heaven of God's holy Will is to establish unity and concord amongst the peoples of the world; make it not the cause of dissension and strife. The religion of God and His divine law are the most potent instruments and the surest of all means for the dawning of the light of unity amongst men.
The progress of the world, the development of nations, the tranquillity of peoples, and the peace of all who dwell on earth are among the principles and ordinances of God. Religion bestoweth upon man the most precious of all gifts, offereth the cup of prosperity, imparteth eternal life, and showereth imperishable benefits upon mankind. It behoveth the chiefs and rulers of the world, and in particular the Trustees of God's House of Justice, to endeavour to the utmost of their power to safeguard its position, promote its interests and exalt its station in the eyes of the world. (Baha’u’llah, ‘Tablets of Bahá'u'lláh revealed after the Kitab-i-Aqdas’; The Compilation of Compilations, vol. II, Peace)
