Rabbi Mordecai Kaplan

Rabbi Mordecai Kaplan (1881-1983) was an influential Jewish thinker and rabbi who founded Reconstructionist Judaism, the fourth major movement of American Judaism. He served as a rabbi and professor at the Jewish Theological Seminary of America for over 50 years while developing his distinctive approach to Jewish thought and practice. Kaplan rejected both Orthodox Judaism's supernatural beliefs and Reform Judaism's radical breaks with tradition, instead advocating for Judaism as an evolving religious civilization. His major work, Judaism as a Civilization (1934), presented his vision of Judaism adapted to modern scientific and democratic thinking while maintaining connection to Jewish cultural heritage. The Reconstructionist movement that emerged from Kaplan's philosophy emphasized Jewish peoplehood, ethical monotheism, and the reinterpretation of traditional Jewish concepts and rituals for contemporary life. His liturgical innovations included the first English-language American Jewish prayer book and the first Bat Mitzvah ceremony for girls in 1922. Kaplan's ideas about Jewish civilization, though controversial in his time, influenced modern Jewish thought across denominations. His emphasis on Judaism as an evolving religious culture that must adapt to changing times while preserving its essential character continues to shape American Jewish life and thought.
