Catholic–Orthodox Relations is the history, shared inheritance, remaining divisions, and official dialogue between the Catholic Church and the Eastern Orthodox Churches.[1]

Communion wounded over centuries

Catholics and Eastern Orthodox share the early ecumenical councils, apostolic succession, episcopal ministry, the Eucharist and other sacraments, devotion to Mary and the saints, and much patristic theology. Their separation was a long process shaped by language, politics, jurisdictional conflict, the events conventionally dated to 1054, the Latin sack of Constantinople in 1204, and failed or contested reunion councils.

Vatican II calls the separated Eastern Churches true particular Churches and says that through the Eucharist in each of them the Church of God is built up. Catholic discipline permits members of Eastern Churches not in full communion to receive penance, Eucharist, and anointing from Catholic ministers under conditions defined by canon law.

Questions still dividing

The principal theological questions concern the universal primacy of the bishop of Rome and its relation to synodality, certain later Catholic dogmatic definitions, and the history and language of the Filioque. Practical and historical disputes include jurisdiction, proselytism, and the status and activity of Eastern Catholic churches.

The Latin phrase Filioque, meaning 'and the Son,' was added gradually to the creed in Western worship and remains absent from the original Greek text. Catholic teaching recognizes the normative conciliar form, the monarchy of the Father as first origin, and legitimate complementarity between Greek and Latin expressions, while acknowledging an unresolved history of reception and controversy.

Official dialogue

The Joint International Commission for Theological Dialogue began work in 1980. Its agreed texts have addressed the Trinity, Eucharist, sacraments, apostolic succession, authority, synodality, primacy, the first and second millennia, and the rejection of 'uniatism' as a present method for restoring unity. These are dialogue documents rather than acts that by themselves restore communion.[2]

Modern Catholic teaching seeks full communion without erasing legitimate Eastern diversity. John Paul II explicitly invited other Christians to help find an exercise of Roman primacy faithful to its essential mission and open to a new ecumenical situation; the Holy See's 2024 study The Bishop of Rome gathered responses and proposals from decades of dialogue.[3]
