The history, traditions, and theology of Greek Orthodox Christianity are rooted in the early Church Fathers and the culture of the Byzantine Empire, which was heavily Greek. The church traditionally places great emphasis and value to monasticism and asceticism, which are rooted in early Christian practices in the Near East and Byzantine Anatolia.

The Greek Orthodox Church is the national church of Greece, where it is known as the Church of Greece, and the predominant faith among the Greek diaspora, for which it is a central marker of Greek identity.[6] However, the Greek Orthodox Church is not restricted to ethnic Greeks or the Greek language.
