Haredi Judaism ( , ; also spelled
Charedi, plural
Charedim) is a stream of
Orthodox Judaism characterized by rejection of
modern secular culture. Its members are often referred to as
strictly Orthodox or
ultra-Orthodox in English. The term "ultra-Orthodox," however, is considered a derogatory slur by some in the community. Haredim regard themselves as the most religiously authentic group of Jews, although this claim is contested by other streams.
