Judaism, then, far from being the late product of the Torah and tradition, as it is often considered, was actually the creator of the Law. Transformed and unfolded in Babylonia, it created its own sacred literature and shaped it ever anew, filling it always with its own spirit and with new thoughts. It is by no means the petrifaction of the Mosaic law and the prophetic teachings, as we are so often told, but a continuous process of unfolding and regeneration of its great religious truth. 5. True enough, traditional or orthodox Judaism does not share this view. The idea of gradual development is precluded by its conception of divine revelation, by its doctrine that both the oral and the written Torah were given at Sinai complete and unchangeable for all time. It makes allowance only for special institutions begun either by the prophets, by Ezra and the Men of the Great Synagogue, his associates, or by the masters of the Law in succeeding centuries. Nevertheless, tradition says that the Men of the Great Synagogue themselves collected and partly completed the sacred books, except the five books of Moses, and that the canon was made under the influence of the holy spirit. This holy spirit remained in force also during the creative period of Talmudism, sanctioning innovations or alterations of many kinds.(11) Modern critical and historical research has taught us to distinguish the products of different periods and stages of development in both the Biblical and Rabbinical sources, and therefore compels us to reject the idea of a uniform origin of the Law, and also of an uninterrupted chain of tradition reaching back to Moses on Sinai. Therefore we must attach still more importance to the process of transformation which Judaism had to undergo through the centuries.(12)
