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.
List of Dune religions
In "" it is revealed that Jewish communities continue to exist, scattered across the galaxy. In sharp contrast to the drastic changes which have occurred in other religions in the 25,000 years between the 20th century and the time of the Honored Matres invasion, Judaism has undergone comparatively little change. Jewish characters also feature in Brian Herbert and Kevin J. Anderson's sequels, "Hunters of Dune" and "Sandworms of Dune".
