The division over Chalcedon
Schism · 451 · communion not restored
The Definition of Chalcedon divided the churches that received it from those that did not. The division has never been healed, and no council since has been received by both.
The record does not name the two sides of this division, and this project does not supply them: naming one side asserts which of them left. What it does hold is the argument and the day.
The day, and the argument
- Council of Chalcedon the day this is dated from
- The division over Chalcedon what was argued
The year is the event's, not this row's — a division carries no date its own event already states.
