In this wise did they object to that Sun of Truth, although that Spirit of God was indeed the One promised in the Torah. But as they did not understand the meaning of these signs, they crucified the Word of God. Now the Bahá’ís hold that the recorded signs did come to pass in the Manifestation of Christ, although not in the sense which the Jews understood, the description in the Torah being allegorical. For instance, among the signs is that of sovereignty. For Bahá’ís say that the sovereignty of Christ was a heavenly, divine, everlasting sovereignty, not a Napoleonic sovereignty that vanisheth in a short time. For well nigh two thousand years this sovereignty of Christ hath been established, and until now it endureth, and to all eternity that Holy Being will be exalted upon an everlasting throne. In like manner all the other signs have been made manifest, but the Jews did not understand. Although nearly twenty centuries have elapsed since Christ appeared with divine splendour, yet the Jews are still awaiting the coming of the Messiah and regard themselves as true and Christ as false. 21: O THOU DISTINGUISHED PERSONAGE, THOU SEEKER AFTER ... O thou distinguished personage, thou seeker after truth! Thy letter of 4 April 1921, hath been read with love. The existence of the Divine Being hath been clearly established, on the basis of logical proofs, but the reality of the Godhead is beyond the grasp of the mind. When thou dost carefully consider this matter, thou wilt see that a lower plane can never comprehend a higher. The mineral kingdom, for example, which is lower, is precluded from comprehending the vegetable kingdom; for the mineral, any such understanding would be utterly impossible. In the same way, no matter how far the vegetable kingdom may develop, it will achieve no conception of the animal kingdom, and any such comprehension at its level would be unthinkable, for the animal occupieth a plane higher than that of the vegetable: this tree cannot conceive of hearing and sight. And the animal kingdom, no matter how far it may evolve, can never become aware of the reality of the intellect, which discovereth the inner essence of all things, and comprehendeth those realities which cannot be seen; for the human plane as compared with that of the animal is very high. And although these beings all co-exist in the contingent world, in each case the difference in their stations precludeth their grasp of the whole; for no lower degree can understand a higher, such comprehension being impossible. The higher plane, however, understandeth the lower. The animal, for instance, comprehendeth the mineral and vegetable, the human understandeth the planes of the animal, vegetable and mineral. But the mineral cannot possibly understand the realms of man. And notwithstanding the fact that all these entities co-exist in the phenomenal world, even so, no lower degree can ever comprehend a higher.
