Orthodox Dialogue
Follow the consultations, theological agreements, unresolved questions, and continuing encounters that have shaped relations between the Eastern Orthodox and Oriental Orthodox Churches in the modern era.
Section Overview
The Eastern Orthodox and Oriental Orthodox Churches share the Scriptures, the early creeds, the sacramental life of the ancient Church, and a deep inheritance from the Fathers. Yet their ecclesial separation became associated above all with the reception of the Council of Chalcedon in 451 and with the Christological language that developed around it.
Modern dialogue has attempted to address that history by bringing representatives of both families into direct conversation. Rather than relying only on inherited polemics, theologians compared primary texts, clarified technical vocabulary, examined the teaching of St Cyril of Alexandria, and asked whether apparently different formulas were intended to protect the same apostolic confession of Jesus Christ as truly divine and truly human.
The process has produced substantial theological convergence, but it has not by itself created full ecclesial communion. Questions of reception, councils, anathemas, canonical practice, liturgical life, and the authority of agreements within individual churches remain important to understanding the present state of the dialogue.
Two Major Phases
1964–1971
Meetings at Aarhus, Bristol, Geneva, and Addis Ababa created a setting in which theologians could compare the Christological traditions of the two Orthodox families without the immediate burden of negotiating formal ecclesial decisions. These consultations helped expose the importance of terminology, historical context, and common patristic sources.
From 1985
After two decades of unofficial encounters, the dialogue entered an official phase through the Joint Commission for the Theological Dialogue between the Orthodox Church and the Oriental Orthodox Churches. Its meetings produced formal texts that addressed Christology, common faith, historical condemnations, and practical steps toward closer ecclesial relations.
Dialogue Timeline
The first major unofficial consultation brought Eastern Orthodox and Oriental Orthodox theologians together to examine the historical Christological disagreement in a new setting of direct conversation.
The second informal consultation continued the comparison of Christological language and explored the degree to which inherited divisions reflected terminology as well as doctrine.
Theologians developed the conversation further by examining the historical reception of councils, teachers, and formulas within the two traditions.
The fourth informal consultation completed the early sequence of meetings that prepared the ground for a later official dialogue.
The official Joint Commission began its work, marking a transition from exploratory theological consultation to an ecclesially mandated process between the two church families.
The First Agreed Statement articulated a substantial common Christological confession and became one of the most important texts produced by the dialogue.
A further meeting at Chambésy developed the theological agreement and addressed how each family understands the language used to confess the one incarnate Christ.
The Joint Commission considered how historical condemnations and anathemas might be addressed in light of the Christological understanding reached in the dialogue.
Representatives of the two families met again at the Ecumenical Patriarchate, reviewing previous achievements and discussing ways to deepen the theological dialogue and cooperation.
What the Dialogue Achieved
One of the most significant results of the dialogue has been the recognition that older labels can obscure what each tradition actually confesses. Oriental Orthodox churches reject Eutychianism and do not teach that Christ’s humanity is absorbed into his divinity. Eastern Orthodox churches, for their part, understand Chalcedon’s language of Christ “in two natures” as preserving the unity of the one Son while safeguarding the full reality of both divinity and humanity.
The agreed statements therefore attempted to express a common Christological faith without requiring either family simply to abandon its inherited theological vocabulary. That approach does not make the historical disagreements insignificant. It instead asks a more precise question: which differences concern the substance of faith, and which reflect language, historical reception, or distinct theological emphases?

The Question of Reception
A theological commission can clarify doctrine and propose a path forward, but communion between church families involves more than the publication of a joint text. Agreements must be received, evaluated, and acted upon within the life and authority structures of the participating churches.
This helps explain why strong Christological convergence can coexist with continuing ecclesial separation. The status of the Council of Chalcedon, the treatment of historical anathemas, recognition of saints and teachers, canonical questions, pastoral practice, and the practical reception of commission texts are not identical issues, even though they are connected.
The result is a dialogue that should neither be described as a failure nor treated as already complete. It has changed the theological landscape by replacing many inherited caricatures with direct comparison of sources and explicit common statements, while leaving a further ecclesial process that cannot be reduced to Christology alone.
Reading the Dialogue
Use the 1964–1971 meetings to understand how direct theological exchange developed before the official commission began.
The two statements are best read as a sequence. They show how the commission articulated common Christological convictions while preserving the vocabulary of both traditions.
Responses from individual churches, discussion of anathemas, and later encounters reveal why theological consensus and ecclesial communion must be distinguished.
Frequently Asked Questions
Short answers to common questions about the history, status, and purpose of the Eastern Orthodox–Oriental Orthodox dialogue.
The modern sequence began with unofficial theological consultations at Aarhus in 1964, followed by Bristol in 1967, Geneva in 1970, and Addis Ababa in 1971. The official Joint Commission began its work in 1985.
It is the formal theological dialogue body bringing together representatives of the Eastern Orthodox and Oriental Orthodox church families. Its work has included Christology, historical condemnations, ecclesial reception, and proposals related to closer relations between the two families.
The agreed statements expressed substantial common Christological conviction and emphasized that both families confess the one Lord Jesus Christ as truly divine and truly human. The significance and reception of those statements, however, remain ecclesial questions within the participating churches.
No. The two families remain outside full sacramental communion despite major progress in theological understanding and significant areas of cooperation.
The early meetings allowed theologians to compare historical sources and vocabulary in a less formal setting. Their work helped create the theological groundwork for an officially mandated commission beginning in 1985.
Yes. Representatives of the two Orthodox families met again in 2024 under the auspices of the Ecumenical Patriarchate, reviewing the history of the dialogue and discussing further theological and practical cooperation.
