To gain a comprehensive knowledge of this literature, Richard Simon was obliged, like Reuchlin before him, to seek intercourse with Jews; in particular he associated with Jonah Salvador, the Italian Sabbatian. By this means he lost a part of his prejudice against Jews, which still existed in France in its intensity. He was drawn to Jews in another direction. Laying stress on Catholic tradition as opposed to the literal belief of the Protestants, he felt in some degree related to the Talmudists and Rabbanites. They also upheld their tradition against the literal belief of the Karaites. Richard Simon, therefore, exalted Rabbinical Judaism in the introduction and supplements which he added to his translation of Leo Modena's "Rites." Familiar with the whole of Jewish literature as few of his time or of a later period, Richard Simon refrained from making the boastful assertion, grounded upon ignorance, that Christianity is something peculiar, fundamentally different to Judaism and far more exalted. He recognized, and had the courage to declare, the truth that Christianity in its substance and form was molded after the pattern of Judaism, and would have to become like it again. "Since the Christian religion has its origin in Judaism, I doubt not that the perusal of this little book (the 'Rites') will contribute to the understanding of the New Testament, on account of its similarity to, and close connection with the Old. They who composed it were Jews, and it can be explained only by means of Judaism. A portion of our ceremonies also are derived from the Jews.... The Christian religion has this besides in common with the Jewish, that each is based on Holy Scripture, on the tradition of the fathers, on traditional habits and customs.... One cannot sufficiently admire the modesty and devotion of the Jews, as they go to prayer in the morning.... The Jews distinguish themselves, not only by prayers, but also by deeds of mercy, and one thinks one sees, in their sympathy for the poor, the image of the love of the first Christians for their brethren. Men obeyed in those times what the Jews have retained to this day, while we (Christians) have scarcely kept up the remembrance of it."
