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.
The Ecumenical Council of Nicaea, AD 325
The first Council of Nicaea was convened in the early summer of AD 325 by Roman Emperor Constantine at what is today Iznik, Turkey. The emperor presided at the opening of the council. The council ruled against the Arians, who taught that Jesus was not the eternal Son of God but was created by the Father and was called Son of God because of His righteousness. The chief opponents of the Arians were Alexander, bishop of Alexandria, and his deacon, Athanasius. The council confessed the eternal divinity of Jesus and adopted the earliest version of the Nicene Creed, which in its entirety was adopted at the Council of Constantinople in AD 381.
