The Orthodox-Catholic Christian tradition is the broad apostolic inheritance shared by historic Eastern and Western churches that confess the ancient creeds, preserve episcopal succession, and celebrate a sacramental and liturgical Christian life.
Common inheritance
This inheritance includes Holy Scripture within Tradition, the early councils and Fathers, baptism and Eucharist, bishops, priests and deacons, devotion to the saints, and the conviction that the visible Church continues the apostolic mission.
Unity and diversity
Eastern Orthodox, Oriental Orthodox, Roman Catholic, Old Catholic, Anglican, and other bodies do not form one institutional communion, and important doctrinal differences remain. The expression identifies substantial common roots without erasing those differences.
Rome-Ruthenia
The United Roman-Ruthenian Church understands its own vocation at the meeting point of Eastern and Western apostolic traditions, with Byzantine, Gallican, and Anglican inheritances represented in its ecclesial life.
