Haredi Judaism is a branch of Orthodox Judaism that is characterized by its strict interpretation of religious sources and its accepted halakha and traditions, in opposition to more accommodating values and practices. Its members are often referred to as "ultra-Orthodox" in English, a term considered pejorative by many of its adherents, who prefer the terms strictly Orthodox or Haredi. Haredim regard themselves as the most authentic custodians of Jewish religious law and tradition which, in their opinion, is binding and unchangeable. They consider all other expressions of Judaism, including, sometimes, Modern Orthodoxy, as "deviations from God's laws", although other movements of Judaism would disagree.
