Owing to these two opposing forces, the one centripetal, the other centrifugal, Judaism tended now inward, away from world-culture, now outward toward the learning and the thought of all nations; and this makes it doubly difficult to obtain a true estimate of its character. But, after all, these very currents and counter-currents at the different eras of history kept Judaism in continuous tension and fluctuation, preventing its stagnation by dogmatic formulas and its division by ecclesiastical dissensions. “Both words are the words of the living God” became the maxim of the contending schools.9

4. If we now ask what period we may fix as the beginning of Judaism, we must by no means single out the decisive moment when Ezra the Scribe established the new commonwealth of JudÆa, based upon the Mosaic book of Law, and excluding the Samaritans who claimed to be the heirs of ancient Israel. This important step was but the climax, the fruitage of that religious spirit engendered by the Judaism of the Babylonian exile. The Captivity had become a refining furnace for the people, making them cling with a zeal unknown before to the teachings of the prophets, now offered by their disciples, and to the laws, as preserved by the priestly guilds; so the religious treasures of the few became the common property of the many, and were soon regarded as “the inheritance of the whole congregation of Jacob.” As a matter of fact, Ezra represents the culmination rather than the starting point of the great spiritual reawakening, when he came from Babylon with a complete Code of Law, and promulgated it in the Holy City to a worshipful congregation.10 It was Judaism, winged with a new spirit, which carried the great unknown seer of the Exile to the very pinnacle of prophetic vision, and made the Psalmists ring forth from the harp of David the deepest soul-stirring notes of religious [pg 011] devotion and aspiration that ever moved the hearts of men. Moreover, all the great truths of prophetic revelation, of legislative and popular wisdom, were then collected and focused, creating a sacred literature which was to serve the whole community as the source of instruction, consolation, and edification. The powerful and unique institutions of the Synagogue, intended for common instruction and devotion, are altogether creations of the Exile, and replaced the former priestly Torah by the Torah for the people. More wonderful still, the priestly lore of ancient Babylon was transformed by sublime monotheistic truths and utilized in the formation of a sacred literature; it was placed before the history of the Hebrew patriarchs, to form, as it were, an introduction to the Bible of humanity.

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, [pg 012] 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

Judaism manifested its wondrous power of assimilation by renewing itself to meet the demands of the time, first under the influence of the ancient civilizations, Babylonia and Persia, then of Greece and Rome, finally of the Occidental powers, molding its religious truths and customs in ever new forms, but all in consonance with its own genius. It adopted the Babylonian and Persian views of the hereafter, of the upper and the nether world with their angels and demons; so later on it incorporated into its religious and legal system elements of Greek and Egyptian gnosticism, Greek philosophy, and methods of jurisprudence from Egypt, Babylon, and Rome. In fact, the various parties which arose during the second Temple beside each other or successively—Sadducees and Pharisees, Essenes and Zealots—represent, on closer observation, the different stages in the process of assimilation which Judaism had to undergo. In like manner, the Hellenistic, Apocryphal and Apocalyptic literature, which was rejected and lost to sight by traditional Judaism, and which partly fills the gap between the Bible and the Talmudic writings, casts a flood of light upon the development of the Halakah [pg 013] and the Haggadah. Just as the book of Ezekiel, which was almost excluded from the Canon on account of its divergence from the Mosaic Law, has been helpful in tracing the development of the Priestly Code,13 so the Sadduceean book of Ben Sira14 and the Zealotic book of Jubilees15—not to mention the various Apocalyptic works—throw their searchlight upon pre-Talmudic Judaism.

6. Instead of representing Judaism—as the Christian theologians do under the guise of scientific methods—as a nomistic religion, caring only for the external observance of the Law, it is necessary to distinguish two opposite fundamental tendencies; the one expressing the spirit of legalistic nationalism, the other that of ethical or prophetic universalism. These two work by turn, directing the general trend in the one or the other direction according to circumstances. At one time the center and focus of Israel's religion is the Mosaic Law, with its sacrificial cult in charge of the priesthood of Jerusalem's Temple; at another time it is the Synagogue, with its congregational devotion and public instruction, its inspiring song of the Psalmist and its prophetic consolation and hope confined to no narrow territory, but opened wide for a listening world. Here it is the reign of the Halakah holding fast to the form of tradition, and there the free and fanciful Haggadah, with its appeal to the sentiments and views of the people. Here it is the spirit of ritualism, bent on separating the Jews from the influence of foreign elements, and there again the spirit of rationalism, eager to take part in general culture and in the progress of the outside world.

The liberal views of Maimonides and Gersonides concerning [pg 014] miracle and revelation, God and immortality were scarcely shared by the majority of Jews, who, no doubt, sided rather with the mystics, and found their mouthpiece in Abraham ben David of Posquieres, the fierce opponent of Maimonides. An impartial Jewish theology must therefore take cognizance of both sides; it must include the mysticism of Isaac Luria and Sabbathai Horwitz as well as the rationalism of Albo and Leo da Modena. Wherever is voiced a new doctrine or a new view of life and life's duty, which yet bears the imprint of the Jewish consciousness, there the well-spring of divine inspiration is seen pouring forth its living waters.

7. Even the latest interpretation of the Law, offered by a disciple who is recognized for true conscientiousness in religion, was revealed to Moses on Sinai, according to a Rabbinical dictum.16 Thus is exquisitely expressed the idea of a continuous development of Israel's religious truth. As a safeguard against arbitrary individualism, there was the principle of loyalty and proper regard for tradition, which is aptly termed by Professor Lazarus a “historical continuity.”17 The Midrashic statement is quite significant that other creeds founded on our Bible can only adhere to the letter, but the Jewish religion possesses the key to the deeper meaning hidden and presented in the traditional interpretation of the Scriptures.18 That is, for Judaism Holy Scripture in its literal sense is not the final word of God; the Bible is rather a living spring of divine revelation, to be kept ever fresh and flowing by the active force of the spirit. To sum up: Judaism, far from offering a system of beliefs and ceremonies fixed for all time, is as multifarious and manifold in its aspects as is life itself. It comprises all phases and characteristics of both a national and a world religion.
