Non-reception of Chalcedon
The Council of Chalcedon is not received as a binding ecumenical norm.
What it is: The belief holds that the Chalcedonian definition of 451 should not be received as a binding ecumenical formulation by these churches.
How the tradition understands it: The rejection is usually presented not as a rejection of the full humanity of Christ, but as a refusal of language historically seen as liable to dualize Christ or betray the legacy of Cyril of Alexandria.
Textual basis or tradition: The readings of Cyril, the reception of Ephesus, and the historical memory of controversies with the empire are decisive.
Historical context: The non-acceptance of Chalcedon was the main point of institutional separation between these churches and the Chalcedonian tradition.
Common objections: Critics argue that the rejection prolonged schisms and misunderstandings that could have been resolved by more careful interpretation.
Internal variations: Modern dialogues show relevant Christological rapprochements, but without altering the historical memory of non-reception.
