Revealed soon after Bahá’u’lláh had been transferred to the house of Údí Ḵẖammár (circa 1873), at a time when He was still encompassed by the tribulations that had afflicted Him, through the acts committed by His enemies and the professed adherents of His Faith, this Book, this treasury enshrining the priceless gems of His Revelation, stands out, by virtue of the principles it inculcates, the administrative institutions it ordains and the function with which it invests the appointed Successor of its Author, unique and incomparable among the world’s sacred Scriptures. For, unlike the Old Testament and the Holy Books which preceded it, in which the actual precepts uttered by the Prophet Himself are non-existent; unlike the Gospels, in which the few sayings attributed to Jesus Christ afford no clear guidance regarding the future administration of the affairs of His Faith; unlike even the Qur’án which, though explicit in the laws and ordinances formulated by the Apostle of God, is silent on the all-important subject of the succession, the Kitáb-i-Aqdas, revealed from first to last by the Author of the Dispensation Himself, not only preserves for posterity the basic laws and ordinances on which the fabric of His future World Order must rest, but ordains, in addition to the function of interpretation which it confers upon His Successor, the necessary institutions through which the integrity and unity of His Faith can alone be safeguarded. In this Charter of the future world civilization its Author—at once the Judge, the Lawgiver, the Unifier and Redeemer of mankind—announces to the kings of the earth the promulgation of the "Most Great Law"; pronounces them to be His vassals; proclaims Himself the "King of Kings"; disclaims any intention of laying hands on their kingdoms; reserves for Himself the right to "seize and possess the hearts of men"; warns the world’s ecclesiastical leaders not to weigh the "Book of God" with such standards as are current amongst them; and affirms that the Book itself is the "Unerring Balance" established amongst men. In it He formally ordains the institution of the "House of Justice", defines its functions, fixes its revenues, and designates its members as the "Men of Justice", the "Deputies of God", the "Trustees of the All-Merciful"; alludes to the future Centre of His Covenant, and invests Him with the right of interpreting His holy Writ; anticipates by implication the institution of Guardianship; bears witness to the revolutionizing effect of His World Order; enunciates the doctrine of the "Most Great Infallibility" of the Manifestation of God; asserts this infallibility to be the inherent and exclusive right of the Prophet; and rules out the possibility of the appearance of another Manifestation ere the lapse of at least one thousand years.
