History has amply demonstrated that religion can serve either as a powerful instrument for cooperation to propel the advancement of civilization, or as a source of conflict that yields incalculable harm. The unifying and civilizing power of religion begins to decline as the followers come to disagree on the meaning and application of the divine teachings, and the community of the faithful eventually becomes divided into contending sects and denominations. The purpose of Bahá’u’lláh’s Revelation is to establish the oneness of humanity and unite all peoples, and this last and highest stage in the evolution of society cannot be achieved if the Bahá’í Faith succumbs to the malady of sectarianism and the dilution of the divine Message witnessed in the past. If Bahá’ís “cannot unite around one point”, ‘Abdu’l-Bahá observes, “how will they be able to bring about the unity of mankind?” And He affirms: “Today the dynamic power of the world of existence is the power of the Covenant which like unto an artery pulsateth in the body of the contingent world and protecteth Bahá’í unity.”
