“It is evident,” He[Bahá’u’lláh], in another passage explains, “that every age in which a Manifestation of God hath lived is divinely-ordained, and may, in a sense, be characterized as God’s appointed Day. This Day, however, is unique, and is to be distinguished from those that have preceded it. The designation ‘Seal of the Prophets’ fully revealeth its high station. The Prophetic Cycle hath verily ended. The Eternal Truth is now come. He hath lifted up the ensign of power, and is now shedding upon the world the unclouded splendor of His Revelation.”
