That all the Messengers of God should be regarded as “abiding in the same Tabernacle, soaring in the same Heaven, seated upon the same Throne, uttering the same Speech, and proclaiming the same Faith” must, however much we may extol the measure of Divine Revelation vouchsafed to mankind at this crowning stage of its evolution, remain the unalterable foundation and central tenet of Bahá’í belief. Any variations in the splendor which each of these Manifestations of the Light of God has shed upon the world should be ascribed not to any inherent superiority involved in the essential character of any one of them, but rather to the progressive capacity, the ever-increasing spiritual receptiveness, which mankind, in its progress towards maturity, has invariably manifested.
