Reform Judaism, also known as Liberal Judaism or Progressive Judaism, is a major Jewish denomination that emphasizes the evolving nature of Judaism, the superiority of its ethical aspects to its ceremonial ones, and belief in a continuous revelation which is closely intertwined with human reason and not limited to the theophany at Mount Sinai. A liberal strand of Judaism, it is characterized by little stress on ritual and personal observance, regarding Jewish law as non-binding and the individual Jew as autonomous, and by a great openness to external influences and progressive values.
The origins of Reform Judaism lie in mid-19th-century Germany, where Rabbi Abraham Geiger and his associates formulated its basic principles, attempting to harmonize Jewish tradition with modern sensibilities in the age of emancipation. Understanding Jewish tradition in terms of historical-critical methods and modern philosophy, seeing it as constantly evolving, the early Reform movement sanctioned a conscious adaptation of religious life and the ommission of observances and beliefs considered irrelevant or superstitious. In the public sphere it removed parts of the liturgy pertaining to concepts discarded by it, like bodily resurrection of the dead or the restoration of the sacrifical cult in Jerusalem, and translated much of the prayer from Hebrew to the vernacular German. In the private sphere it condoned and legitimized the widespread abandonment of personal observance of dietary, Sabbath and other ritual laws. European Reform was often conservative, having to co-exist with traditionalist elements within long-established communities. Brought to America by German-born rabbis, the denomination gained prominence in the United States, flourishing from the 1860s to the 1930s in an era known as "Classical Reform". In the American setting, Reform Judaism was free to exercise its ideas without restriction, adopting a universalist approach with little place for Jewish particularism and disposing of most traditional practice. Almost all of the liturgy was in English, converts and male babies were not required to undergo circumcision, and many congregations celebreated the Sabbath also on Sunday. The arrival in America of numerous Eastern European Jewish immigrants, who were generally traditional, led to a renewed interest in observance and collective identity, officially enshrined by the 1937 Columbus platform. Since the 1970s, the movement has adopted a policy of inclusiveness and acceptance, inviting as many as possible to partake in its communities rather than adhering to strict theoretical clarity, becoming extremely diverse. It is strongly identified with progressive and liberal agendas in political and social terms, mainly under the traditional Jewish rubric tikkun olam ("repairing of the world"). Tikkun olam is a central motto of Reform Judaism, and acting in its name is one of the main channels for adherents to express their affiliation. The movement's most significant center is in North America.
