The diversity of religion shall cease!

"We desire but the good of the world and the happiness of the nations; that all nations shall become one in faith and all men as brothers; that the bonds of affection and unity between the sons of men shall be strengthened; that diversity of religion shall cease and differences of race be annulled. So it shall be; these fruitless strifes, these ruinous wars shall pass away, and the 'Most Great Peace' shall come (Baha'u'llah)."
