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.
