The crisis facing modern Judaism runs deeper than conflicts over religious law - it stems from a fundamental weakening of faith that once animated Jewish religious practice. Even self-identified Orthodox Jews increasingly disregard halakhah (Jewish law), revealing a growing chasm between formal observance and genuine religious conviction. Through theological and historical analysis, this research traces the evolution of Jewish law from a dynamic oral tradition to the codified rigidity of the Shulhan Arukh, examining how this transformation impacts contemporary religious life. The investigation identifies three pillars that historically united Jewish practice: faith in divine purpose and human responsibility, Jewish peoplehood's special mission, and halakhah as sacred discipline reflecting divine will. While traditional halakhah maintained relevance through continuous reinterpretation, its eventual fixing in written codes created an inflexibility ill-suited to changing times. Today's Jews largely follow secular patterns while maintaining superficial religious identification, demonstrating a profound disconnect between faith and practice. Revitalizing Judaism requires reconnecting these elements through reinterpreting traditional concepts in contemporary terms, drawing on the classical interplay between written and oral Torah to create meaningful modern religious life.
