Throughout Jewish history, revolutionary events and subversive ideas have burst forth, repeatedly transforming Jewish experience. Re-forming Judaism seeks to explore these ideas-and the individuals behind them-by delving into historical disruptions that led to lasting change in Jewish thought. A distinguished array of scholars take us on a journey from the disruptive prophets of ancient times, through rational, mystical, and extremist medievalists, to the impact of Haskalah and early Reform thought in modernity. Contemporary innovations such as changes in liturgy and music, feminism, and post-Holocaust theology are included, as are insights into Sephardic and North African experiences. By showing how Judaism forms-then re-forms, and re-forms again-the contributors demonstrate that tensions between continuity and change have always been part of Jewish life, helping us to both understand the past and contemplate the future.
