First Council of Constantinople

Why this council matters

This council belongs to the development of the Church’s explicit Trinitarian confession. It defended Nicene faith and rejected denials of the Holy Spirit’s divinity. Its significance is therefore central to Christian worship, not restricted to an ancient dispute.

The creed commonly associated with Nicaea and Constantinople should be read alongside the earlier creed of 325. The council’s disciplinary arrangements, including the standing of Constantinople, also belong to the history of relations among the major churches. Later reception is part of that history.
