Orthodoxy

Orthodoxy (from Greek: ὀρθοδοξία, orthodoxía, 'righteous/correct opinion')[1][2] is adherence to correct or accepted creeds, especially in religion.[3]

Orthodoxy within Christianity refers to acceptance of the doctrines defined by various creeds and ecumenical councils in Antiquity, but different Churches accept different creeds and councils. Such differences of opinion have developed for numerous reasons, including language and cultural barriers. The Eastern Orthodox Church adheres to the orthodoxy portrayed mainly in the first seven ecumenical councils, while the Oriental Orthodox Churches define their orthodoxy as based on the first three ecumenical councils alone.[4][5]

In some English-speaking countries, Jews who adhere to all the traditions and commandments as legislated in the Talmud are often called Orthodox Jews.
