Aspects of the connection between Judaism and Christianity in Franz Rosenzweig’s philosophy

The novelty in Rosenzweig’s new ways of thinking lies in the fact that, unlike the traditional view, in his thought philosophy is the discipline containing a subjective element, whereas religion is more objective since it is founded on revelation. These complementary differences help the philosopher rethink Judaism and Jewish identity in the context of the spiritual crisis of the secularized Judaism of his time. Starting with the analysis of this reconstruction of philosophy, this text attempts to present a balanced perspective on Rosenzweig’s vision of the relation between Judaism and Christianity. We will not single out the common elements or those that separate these two monotheist religions; setting Judaism and Christianity on the same level is considered to be a compensatory gesture towards Judaism and Jewish tradition. There is in Rosenzweig a significant moment of approach toward Christianity, especially to a Christianity without Christ, but Rosenzweig opts for a different solution, that of building a new philosophy based on Judaism. Moshe Idel’s analysis suggests that it is the Kabbalistic mysticism that Rosenzweig redefines in order to propose a new way of thought based on both philosophy and religion. Thus, Rosenzweig gives new meaning to the balance of divine and human in the field of religion.
