Today, June 12th, the Church commemorates the Ecumenical Council of Nicaea, which took place in AD 325. This was the first Council of Nicaea, and it was convened by the Emperor Constantine. It was held in what is now Iznik, Turkey. Constantine presided over the council, which ruled against the A***ns. The A***ns taught the A***n Heresy, that Jesus was not the eternal Son of God, but was created by the Father and given the title Son of God only because of His righteousness. Against this heresy, the council confessed the eternal divinity of Jesus, led especially by Alexander, Bishop of Alexandria, and his deacon, Athanasius. An early version of the Nicene Creed was adopted by this council, and later the entirety of the creed, as we now have it, was adopted by the Council of Constance in AD 381.
Let us pray: “Lord God, heavenly Father, at the first ecumenical Council of Nicaea, Your Church boldly confessed that it believed in one Lord Jesus Christ as being of one substance with the Father. Grant us courage to confess this saving faith with Your Church through all the ages; through Jesus Christ, our Lord.” Amen.
