Mordecai M. Kaplan

Mordecai M. Kaplan (1881-1983) was an American rabbi, educator, and the founder of Reconstructionist Judaism. As one of the most influential Jewish thinkers of the 20th century, he radically reimagined Judaism as an evolving religious civilization rather than a set of fixed beliefs and practices. During his long tenure at the Jewish Theological Seminary, Kaplan developed his naturalistic interpretation of Judaism, rejecting supernatural elements while preserving Jewish traditions and rituals as cultural expressions. His major work "Judaism as a Civilization" (1934) outlined his vision for modernizing Jewish life and thought, advocating for the adaptation of Jewish practices to contemporary American society. Kaplan established the Society for the Advancement of Judaism in 1922 and later founded the Reconstructionist movement, which became the fourth major branch of American Judaism. His innovative ideas about Jewish community, democracy, and religious naturalism sparked considerable controversy within traditional Jewish circles, leading to the formal excommunication of his prayer book by Orthodox rabbis in 1945. Beyond his theological work, Kaplan made lasting contributions to Jewish education through his development of the "synagogue-center" concept, which integrated religious, cultural, and social activities into a single community institution. His extensive diary, spanning over 50 years, provides valuable insights into the evolution of American Judaism during a period of significant change.
