First Council of Constantinople

The First Council of Constantinople (second ecumenical council) was called by Theodosius I in 381 to confirm the Nicene creed and deal with other matters of the Arian controversy.

[Meletius of Antioch]], [Gregory Nazianzen]?, and Nectarius? successively presided. Gregory Nazianzen was made patriarch, but soon resigned, and Nectarius was then put in his place.

Seven canons, four doctrinal and three disciplinary, are attributed to the council and accepted by the Greek Church, but the Roman Church accepts only the first four.
