Establishing the core tenets of Judaism in the modern era is even more difficult, given the number and diversity of the contemporary Jewish denominations. Even if to restrict the problem to the most influential intellectual trends of the nineteenth and twentieth century, the matter remains complicated. Thus for instance, Joseph Soloveitchik's (associated with the Modern Orthodox movement) answer to modernity is constituted upon the identification of Judaism with following the halakha whereas its ultimate goal is to bring the holiness down to the world. Mordecai Kaplan, the founder of the Reconstructionist Judaism, abandons the idea of religion for the sake of identifying Judaism with civilization and by means of the latter term and secular translation of the core ideas, he tries to embrace as many Jewish denominations as possible. In turn, Solomon Schechter's Conservative Judaism was identical with the tradition understood as the interpretation of Torah, in itself being the history of the constant updates and adjustment of the Law performed by means of the creative interpretation. Finally, David Philipson draws the outlines of the Reform movement in Judaism by opposing it to the strict and traditional rabbinical approach and thus comes to the conclusions similar to that of the Conservative movement.
