The Use of Codified Law in the Rabbinic Courts of Frankfurt am Main on the Eve of the Enlightenment

During the Middle Ages and into the early modern period, rabbinic scholars of law in Franco-German communities had an at best ambivalent attitude toward the codification of Jewish law. Even Rabbi Joseph Caro’s Shul?an ˋArukh, first printed in Venice in 1565, was not well received by all. While students of the law from the lower ranks seem to have embraced the code, many leading rabbis—particularly those in sixteenth- and early seventeenth-century Poland—rejected it. In the course of the mid-seventeenth century, attitudes shifted, and Shul?an ˋArukh became the place for commentaries and learned discussions of the law. By the eighteenth century, rabbinic courts were using Shul?an ˋArukh as the basis of their legal decision making. This is confirmed, at least for Frankfurt am Main, through an examination of the legal diary of Rabbi Nathan Maas (d. 1794). In his diary, Maas not only summarized cases that he heard but also sometimes offered rationales for the court’s decisions. These précis make constant reference to Shul?an ˋArukh and its commentaries while never entering into an analysis of talmudic sources. This cannot have been because of a lack of ability, for Maas and his colleagues on the Frankfurt court were well-known scholars who published talmudic commentaries of substance. The use of a code, even by such authorities, may have been for utilitarian reasons, that is, to speed up the judicial process.
