Reform Judaism (also known as
Liberal Judaism or
Progressive Judaism) is a major confessional division within
Judaism, which emphasizes the evolving nature of the religion, the superiority of its ethical aspects compared to the ceremonial ones, and a belief in a continuous revelation not centered on the theophany at Mount Sinai. It is characterized by a lesser stress on ritual and personal observance, regarding
Jewish Law as of basically non-binding nature, and great openness to external influences and progressive values. The origins of Reform Judaism lay in 19th-century Germany, where its early principles were formulated by Rabbi
Abraham Geiger and his associates, and its greatest center today is in North America.
