Haredi Judaism
Haredi Judaism is not an institutionally cohesive or homogeneous group, but comprises a diversity of spiritual and cultural orientations, generally divided into a broad range of Hasidic sects, Litvishe-Yeshivish streams from Eastern Europe, and Oriental Sephardic Haredim. These groups often differ significantly from one another in their specific ideologies and lifestyles, as well as the degree of stringency in religious practice, rigidity of religious philosophy, and isolation from the general culture that they maintain.
Reform Judaism
The various regional branches sharing these beliefs, including the American Union for Reform Judaism (URJ), the Movement for Reform Judaism (MRJ) and Liberal Judaism in Britain, and the Israel Movement for Reform and Progressive Judaism, are all united within the international World Union for Progressive Judaism. Founded in 1926, the WUPJ estimates it represents at least 1.8 million people in 50 countries: close to a million registered adult congregants as well as numerous unaffiliated individuals who identify with it.
