The Assembly of the Ecumenical Council at Nicea
At the year 325 A.D., 318 fathers assembled in the city of Nicea, in the days of Emperor Constantine, the righteous Emperor. Among them were the heads of the four Sees and they were: Anba Alexandros, the 19th Pope of Alexandria, who was accompanied by Athanasius, his Archdeacon and private secretary; Estasius, archbishop of Antioch; Macarius, Archbishop of Jerusalem. Sylvestros, archbishop of Rome, because of his old age did not attend and sent two priests in his place.The reason for their assembly was to judge Arius who was a priest in Alexandria. He blasphemed against the Son of God, the Lord Jesus Christ by saying that he was not equal in essence to God, His Father, and there was a time when the Son did not exist.
