Not only in the character of the revelation of Bahá'u'lláh, however stupendous be His claim, does the greatness of this Dispensation reside. For among the distinguishing features of His Faith ranks, as a further evidence of its uniqueness, the fundamental truth that in the person of its Forerunner, the Báb, every follower of Bahá'u'lláh recognizes not merely an inspired annunciator but a direct Manifestation of God. It is their firm belief that, no matter how short the duration of His Dispensation, and however brief the period of the operation of His laws, the Báb had been endowed with a potency such as no founder of any of the past religions was, in the providence of the Almighty, allowed to possess. That He was not merely the precursor of the Revelation of Bahá'u'lláh, that He was more than a divinely-inspired personage, that His was the station of an independent, self-sufficient Manifestation of God, is abundantly demonstrated by Himself, is affirmed in unmistakable terms by Bahá'u'lláh, and is finally attested by the Will and Testament of `Abdu'l-Bahá.

Nowhere but in the Kitáb-i-Íqán, Bahá'u'lláh's masterly exposition of the one unifying truth underlying all the Revelations of the past, can we obtain a clearer apprehension of the potency of those forces inherent in that Preliminary Manifestation with which His own Faith stands indissolubly associated. Expatiating upon the unfathomed import of the signs and tokens that have accompanied the Revelation proclaimed by the Báb, the promised Qá'im, He recalls these prophetic words: "Knowledge is twenty and seven letters. All that the Prophets have revealed are two letters thereof. No man thus far hath known more than these two letters. But when the Qá'im shall arise, He will cause the remaining twenty and five letters to be made manifest." "Behold," adds Bahá'u'lláh, "how great and lofty is His station!" "Of His Revelation," He further adds, "the Prophets of God, His saints and chosen ones, have either not been informed, or in pursuance of God's inscrutable Decree, they have not disclosed."

And yet, immeasurably exalted as is the station of the Báb, and marvellous as have been the happenings that have signalized the advent of His Cause, so wondrous a Revelation cannot but pale before the effulgence of that Orb of unsurpassed splendor Whose rise He foretold and whose superiority He readily acknowledged. We have but to turn to the writings of the Báb Himself in order to estimate the significance of that Quintessence of Light of which He, with all the majesty of His power, was but its humble and chosen Precursor.

Again and again the Báb admits, in glowing and unequivocal language, the préeminent character of a Faith destined to be made manifest after Him and to supersede His Cause. "The germ," He asserts in the Persian Bayán, the chief and best-preserved repository of His laws, "that holds within itself the potentialities of the Revelation that is to come is endowed with a potency superior to the combined forces of all those who follow me." "Of all the tributes," the Báb repeatedly proclaims in His writings, "I have paid to Him Who is to come after Me, the greatest is this, My written confession, that no words of Mine can adequately describe Him, nor can any reference to Him in my Book, the Bayán, do justice to His Cause." Addressing Siyyid Yahyáy-i-Darábí, surnamed Vahíd, the most learned and influential among his followers, He says: "By the righteousness of Him Whose power causeth the seed to germinate and Who breatheth the spirit of life into all things, were I to be assured that in the day of His Manifestation thou wilt deny Him, I would unhesitatingly disown thee and repudiate thy faith.... If, on the other hand, I be told that a Christian, who beareth no allegiance to My Faith, will believe in Him, the same will I regard as the apple of Mine eye."
