Containing heresy; of the nature of, or characterized by, heresy.

Against the doctrine or official teaching of the church. The early church held many passionate debates to clarify true and false doctrine about the nature of Christ and salvation. The term is from the Greek "hairesis," meaning party or sect. Paul uses the term both for schism or separation, and for heresy or false doctrine. (See "schism".)

characterized by departure from accepted beliefs or standards

Heretical is a website run by psychologist, neo-Nazi and anti-Semite Simon Sheppard as a repository of material related to his theories of sexual competition and manipulation and his interests in such topics as evolution, genetics, race, sexual behaviour and cannibalism. Among its main areas of interest are the psychology and behaviour of Jews and women, which Sheppard analyses in sometimes negative terms. Amongst other material it contains photographs of Nazi concentration camps with mocking anti-Semitic captions.
