From Wikipedia, the free encyclopedia.
Heterodox literally means pertaining to "other" doctrines or "other" worship. It is contrasted with "orthodox". In Eastern Orthodoxy, the term is used to refer to Christian churches not belonging to the Eastern Orthodox communion and holding doctrines different than Orthodox Christianity, but not as different or as clearly in error as heresy. The word heterodoxy is also used by some other Christians to refer to incorrect religious doctrine.
