The Great Schism
Jurisdictional · 1054 — unsettled · east-west
The quarrel of 1053–54 was about unleavened bread and the creed, argued by legates whose commission had lapsed with the pope who sent them. What it broke had been fraying for centuries and was not repaired.
How it ended. Unsettled. The excommunications of 1054 were lifted in 1965; the communion was not restored.
How it ran
- 1054 — The Great Schism (where it began). The legates lay the bull on the altar of Hagia Sophia.
What it broke
- Schism, 1054 the communion was not restored

What was at issue
