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.
Panarion
The first section of the first of the three books contains an account of 20 heretical sects before the time of Jesus; the remaining portion is occupied with the description of 60 sects of Christianity. However, the total number of sects is actually 77, because three of the first 20 are general names: Hellenism, Samaritanism, and Judaism. In the editions of the "Panarion", each heresy is numbered in order; hence it is customary to quote the "Panarion" as follows: Epiphanius, "Haer." N [the number of the heresy].
