Schism · 484 · 28 July
Acacian Schism begins
The Council of Chalcedon (451) had said that Jesus is one person, fully God and fully human. Many Eastern Christians feared its wording separated Christ's divinity from his humanity; others thought that wording was necessary to protect the faith. Emperor Zeno tried to end the quarrel with the Henotikon: a statement that avoided the disputed Chalcedonian language. Acacius, the bishop of Constantinople, supported it. Pope Felix III in Rome thought the compromise blurred an essential teaching, so he excommunicated Acacius in 484. Rome and Constantinople then stopped sharing communion for 35 years, until 519.

How it happened
What happened
Pope Felix III in Rome broke communion with Acacius, bishop of Constantinople, after Acacius backed the Henotikon, an imperial attempt to settle the post-Chalcedon dispute.
The argument
Could the church preserve peace by avoiding Chalcedon's disputed language, or would that leave an essential teaching about Christ unclear?
What changed
Rome and Constantinople entered their first formal schism.
Why it matters
It shows a recurring Christian dilemma: can a carefully vague formula heal a division, or does clarity about the faith matter more than a quick political peace?
Aftermath
The schism was healed in 519, but it foreshadowed later Rome-Constantinople breaks.
