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.
Religious denomination
The movements differ in their views on various issues. These issues include the level of observance, the methodology for interpreting and understanding Jewish law, biblical authorship, textual criticism, and the nature or role of the messiah (or messianic age). Across these movements there are marked differences in liturgy, especially in the language in which services are conducted, with the more traditional movements emphasizing Hebrew. The sharpest theological division occurs between Orthodox and non-Orthodox Jews who adhere to other denominations, such that the non-Orthodox movements are sometimes referred to collectively as the "liberal denominations" or "progressive streams."
