8. It is true that the accumulation of “law upon law, prohibition upon prohibition” by the rabbis had eventually the same injurious effect which it had exerted upon the priests in the Temple. The formal law, “the precepts learned by rote,” became the important factor, while their purpose was lost to sight. The shell smothered the kernel, and blind obedience to the letter of the law came to be regarded as true piety. It cannot be denied that adherence to the mere form, which was transmitted from the Temple practice to the legalism of the Pharisees and the later rabbinic schools with their casuistry, impaired and tarnished the lofty prophetic ideal of holiness. It almost seems as if the clarion notes of such sublime passages as that of the Psalmist, “Who shall ascend into the mountain of the Lord, And who shall stand in His holy place? He that hath clean hands and a pure heart; Who hath not taken My name in vain, and hath not sworn deceitfully,”(1128) no longer found its full resonance in the heart of Judaism. In the practice of external acts of piety religion became petrified and the spirit took flight. That which is of secondary importance became of primary consideration. This is the fundamental error into which the practice and the development of the Law in Judaism lapsed, and to which no careful observer can or dares close his eyes. Undoubtedly the Law, as it embraced the whole of life in its power, sharpened the Jewish sense of duty, and served the Jew as an iron wall of defense against temptations, aberrations, and enticements of the centuries. As soon as the modern Jew, however, undertook to free himself from the tutelage of a blind acceptance of authority and inquired after the purpose of all the restrictions which the Law laid upon him, his ancient loyalty to the same collapsed and the pillars of Judaism seemed to be shaken. Then the leaders of Reform, imbued with the prophetic spirit, felt it to be their imperative duty to search out the fundamental ideas of the priestly law of holiness, and, accordingly, they learned how to separate the kernel from the shell. In opposition to the orthodox tendency to worship the letter, they insisted on the fact that Israel’s separation from the world—which it is ultimately to win for the divine truth—cannot itself be its end and aim, and that blind obedience to the law does not constitute true piety. Only the fundamental idea, that Israel as the “first-born” among the nations has been elected as a priest-people, must remain our imperishable truth, a truth to which the centuries of history bear witness by showing that it has given its life-blood as a ransom for humanity, and is ever bringing new sacrifices for its cause.
