… ever since the dawn of the world, until this heavenly Dispensation, no such Covenant and Testament hath ever before been established in the heights of the realms above or in the midmost heart of the Abhá Kingdom. From the earliest appearance of the resplendent Fire upon Sinai, until the setting of the luminous Day-Star of the Praised Beauty, no Sacred Text was revealed but that, whether explicitly or implicitly, it made mention of this Eternal Covenant and Ancient Testament, praised and commended those who hold fast unto it, and censured and admonished those who waver and violate it.
Then Bahá’u’lláh, with His own Pen, and tracing in His own hand glorious words across the snow-white pages, made a Covenant with all created things, visible and invisible, and called it “The Book of My Covenant”, and set down in it these words: “The Will of the divine Testator is this …” One must be fair in judgement! Consider how carefully the Blessed Beauty proceeded. Even in the Kitáb-i-Aqdas, which hath abrogated all other sacred Books, He hath stated this theme in lucid and explicit language and not through allusion or symbolic terms, and hath expounded it, in numerous instances, with the utmost authority and power. Wherefore, shame be upon the foolish people because of whom we have been made the target of idle fancies and vain imaginings, nay, even been pierced by their spears and arrows of doubts.
