Council of Nicaea, First Ecumenical Council - 325 A.D.

The Nicene Council is considered by all as the first Ecumenical Council of the Church (Roman Catholic Church). It was occasioned by the Arian "heresy" which in effect denied the divinity of Jesus Christ. The major product of this council was the Creed, the "Nicene Creed"; but it also addressed the date of Easter, and the place of the Patriarch of Alexandria.
