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.
Split of Christianity and Judaism
Most historians agree that Jesus or his followers established a new Jewish sect, one that attracted both Jewish and gentile converts. According to New Testament scholar Bart D. Ehrman, a number of early Christianities existed in the first century CE, from which developed various Christian traditions and denominations, including proto-orthodoxy. According to theologian James D. G. Dunn, four types of early Christianity can be discerned: Jewish Christianity, Hellenistic Christianity, Apocalyptic Christianity, and early Catholicism.
