Historicity, continuity and neo-orthodoxy in contemporary judaism

Judaism is not a uniform religion. In it, different groups are differentiated, among which stand out, for their fundamentalism, the orthodox and the ultra-orthodox. The first ones strictly comply with religious precepts, although they coexist with "gentiles" and even lay people, adapting to certain "modern" social behavior. On the contrary, the second ones, called haredi jews or "God-fearing", follow extreme judaism in their interpretation and practice. These groups are today affected by heterodox and secular overmodern influences to such an extent that in the jewish media there is already talk of the emergence of a "new orthodoxy".
