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.
Origins of Christianity
Judaism at this time was divided into antagonistic factions. The main camps were the Pharisees, Saducees, and Zealots, but also included other less influential sects, like the Essenes. The 1st century BCE and 1st century CE saw a number of charismatic religious leaders, contributing to what would become the Mishnah of Rabbinic Judaism, including Yohanan ben Zakkai and Hanina ben Dosa. The ministry of Jesus, according to the account of the Gospels, falls into this pattern of sectarian preachers or teachers with devoted disciples (students).
