Are we uniting with the Eastern Orthodox?

The question of unity between the Coptic Orthodox Church (Oriental Orthodox) and the Eastern Orthodox Church (such as the Greeks, Russians, and Antiochians) is a complex historical and theological matter. While there have been significant dialogues and a spirit of brotherly love, full sacramental union has not yet been achieved.

1. The Historical Divide

The division occurred at the Council of Chalcedon in 451 AD. The Coptic Church, following the theology of St. Cyril of Alexandria, rejected the Chalcedonian definition of "two natures" in Christ, viewing it as a move toward the Nestorian heresy. We maintain the Miaphysite faith—the "One Nature of God the Logos Incarnate." The Eastern Orthodox accepted Chalcedon, and for 1,500 years, they labeled us as "monophysites" (a term we reject as a heretical misrepresentation of our faith).

2. Modern Theological Agreements

In the late 20th century (specifically in the 1980s and '90s), official theological dialogues took place. The theologians from both families agreed that:

• Our underlying Christological faith is essentially the same.
• We both reject the teachings of Eutyches (true monophysitism) and Nestorius.
• The differences in terminology (physis vs. hypostasis) were largely linguistic and political rather than a difference in the essence of faith.

Because of these agreements, the Joint Commission recommended that the "anathemas" (excommunications) against each other's saints be lifted and that moving toward union should begin.

3. Barriers to Union

Despite these agreements, full communion has not been restored for several reasons:

• The Councils: The Eastern Orthodox recognize seven Ecumenical Councils, including Chalcedon. The Coptic Orthodox only recognize the first three (Nicaea, Constantinople, and Ephesus). We cannot accept councils that we believe erred or strayed from the Cyrillian path.
• The Saints: The Eastern Orthodox venerate figures we consider problematic (such as Leo of Rome), and they have historically anathematized our pillars of faith, like St. Dioscorus of Alexandria. Union would require a reconciliation of our calendars and liturgical commemorations.
• Implementation: While some bishops and theologians are ready for union, many within both churches—particularly monastics and more traditionalist groups—are hesitant or openly opposed, fearing a "compromise of the truth" to be politically correct.

4. Current Status

Currently, there are "local" pastoral agreements in some regions. For example, in certain areas of the Middle East and the Diaspora, our bishops may allow for cooperation in matters of marriage or pastoral care under very specific circumstances. However:

• No Intercommunion: A Coptic Orthodox Christian cannot officially receive the Holy Eucharist in an Eastern Orthodox Church, and vice versa.
• No Concelebration: Coptic clergy and Eastern Orthodox clergy do not serve the Divine Liturgy together at the same altar.

Conclusion

While we share a very similar liturgical life, an ascetic tradition, and a common history of martyrdom, we remain separate bodies. The Coptic Orthodox Church remains the "True Orthodox," holding fast to the faith of the Fathers without the additions or "clarifications" of Chalcedon. We pray for the unity of the faith, but only a unity that is based on the absolute truth of Orthodoxy as handed down by the See of St. Mark.
