… another verse in the Gospel wherein He saith: “Heaven and earth shall pass away: but My words shall not pass away.”[Luke 21:33] Thus it is that the adherents of Jesus maintained that the law of the Gospel shall never be annulled, and that whensoever the promised Beauty is made manifest and all the signs are revealed, He must needs re-affirm and establish the law proclaimed in the Gospel, so that there may remain in the world no faith but His faith. This is their fundamental belief. And their conviction is such that were a person to be made manifest with all the promised signs and to promulgate that which is contrary to the letter of the law of the Gospel, they must assuredly renounce him, refuse to submit to his law, declare him an infidel, and laugh him to scorn. This is proved by that which came to pass when the sun of the Muhammadan Revelation was revealed. Had they sought with a humble mind from the Manifestations of God in every Dispensation the true meaning of these words revealed in the sacred books—words the misapprehension of which hath caused men to be deprived of the recognition of the Sadratu’l-Muntahá, the ultimate Purpose—they surely would have been guided to the light of the Sun of Truth, and would have discovered the mysteries of divine knowledge and wisdom.
- Baha’u’llah (‘The Kitab-i-Iqan’)
