What, we may well inquire at this juncture, were the nature and implications of that Revelation [Baha’u’llah’s] which, manifesting itself so soon after the Declaration of the Báb, abolished, at one stroke, the Dispensation which that Faith had so newly proclaimed, and upheld, with such vehemence and force, the Divine authority of its Author? What, we may well pause to consider, were the claims of Him Who, Himself a disciple of the Báb, had, at such an early stage, regarded Himself as empowered to abrogate the Law identified with His beloved Master? What, we may further reflect, could be the relationship between the religious Systems established before Him and His own Revelation—a Revelation which, flowing out, in that extremely perilous hour, from His travailing soul, pierced the gloom that had settled upon that pestilential pit, and, bursting through its walls, and propagating itself as far as the ends of the earth, infused into the entire body of mankind its boundless potentialities, and is now under our very eyes, shaping the course of human society?
