ORTHODOXY

Right belief as compared with heterodoxy or heresy. The term is used in the East to identify those churches (not united with Rome) which accepted the ancient councils, notably Ephesus and Chalcedon, and which call themselves "the holy, orthodox, catholic, Eastern Church." In the West the word is sometimes used to describe a justifiable concern for sound doctrine in the Catholic faith. (Etym. Greek orthos, right + doksa, opinion: orthodoksa, having the right opinion.)
