The Seven Ecumenical Councils


Between 325 and 787 the bishops of the whole Church met seven times to answer the questions on which the Gospel itself depends. These are their stories — what each council faced, what it decided, and why it still matters.

A council is the Church thinking together. When a teaching arose that would have emptied the Gospel of its meaning, the bishops of the whole world gathered, prayed, argued, searched the Scriptures and the Fathers, and confessed with one voice what the Church had always believed. The seven councils below are received by the Orthodox Church as authoritative for all Christians.

I325

The First Council of Nicaea

Nicaea in Bithynia · 325

The Council of Ephesus

IV451

The Council of Chalcedon

Chalcedon · 451

The largest council of the ancient Church drew the line that still defines Orthodox faith in Christ — and paid for it with the first great division of Christendom.

V553

The Second Council of Constantinople

Constantinople · 553

The least famous of the seven, and the one that shows what a council is for: the Church declaring in what sense her own words must be understood.

The Third Council of Constantinople

Constantinople · 680–681

The council that saved human freedom: because Christ willed as a man as well as God, our wills are not overridden by grace but healed by it.

VII787

The Second Council of Nicaea

Nicaea · 787

The last of the seven returned to the city of the first — to defend the icons, and with them the whole claim that God has really entered matter.

Looking for more? The story of what led up to the very first council — the Arian crisis that made it necessary — is told separately in The Road to Nicaea. The councils are also summarised in week 11 of our Catechism Year Plan.
