It should also be borne in mind that, great as is the power manifested by this Revelation and however vast the range of the Dispensation its Author has inaugurated, it emphatically repudiates the claim to be regarded as the final revelation of God’s will and purpose for mankind. To hold such a conception of its character and functions would be tantamount to a betrayal of its cause and a denial of its truth. It must necessarily conflict with the fundamental principle which constitutes the bedrock of Bahá’í belief, the principle that religious truth is not absolute but relative, that Divine Revelation is orderly, continuous and progressive and not spasmodic or final. Indeed, the categorical rejection by the followers of the Faith of Bahá’u’lláh of the claim to finality which any religious system inaugurated by the Prophets of the past may advance is as clear and emphatic as their own refusal to claim that same finality for the Revelation with which they stand identified. “To believe that all revelation is ended, that the portals of Divine mercy are closed, that from the daysprings of eternal holiness no sun shall rise again, that the ocean of everlasting bounty is forever stilled, and that out of the tabernacle of ancient glory the Messengers of God have ceased to be made manifest” must constitute in the eyes of every follower of the Faith a grave, an inexcusable departure from one of its most cherished and fundamental principles.
