Orthodox Christianity is a descriptive term traditionally used to describe Christian communions and denominations with the word "Orthodox" in their English-language names. These are churches which maintained Eastern and Occidental Christian tradition following the Great Schisms which separated the Church universal into different communions.
Increasingly, the word "orthodox", used as an adjective, is used to described mainstream and traditional denominations, to distinguish them from newer evangelical movements.
