When one claims to represent the Eastern Orthodox tradition, this implies that one is following a specific set of hermeneutical presuppositions of the common tradition. All Christian traditions share the same basic sources in the first millennium, so the definition of a theology as “Orthodox” is necessarily related to a specific point of view, to concrete presuppositions, when approaching this common tradition. One such widely recognized special feature of Orthodox theology is its frequent strong emphasis on the patristic heritage (up until the fifteenth century), which somehow marks its distinctive character as the formative factor of its identity.
