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.
Modern Orthodox Judaism
Nevertheless, the two movements are philosophically distinct on two broad counts.Applying the above distinction, in Israel today, Modern Orthodoxy - as distinct from (right-wing) Religious Zionism - is represented by only a select group of institutions: the Religious Kibbutz Movement, Neemanei Torah V'Avoda, the Meimad political party, and the Shalom Hartman Institute, Yeshivat Har Etzion / Migdal Oz and Yeshivat Hamivtar/Ohr Torah Stone Institutions/Midreshet Lindenbaum (some would include Yeshivat Hesder Petach Tikva, Yeshivat Ma'ale Gilboa, and the Tzohar Foundation).
