The Council of Nicaea

The event

In AD 325, the recently converted Roman emperor Constantine summoned bishops from across the Christian world to the city of Nicaea, in what is now northwestern Turkey, to resolve a bitter controversy that had split the church: a presbyter from Alexandria named Arius was teaching that the Son was a created being, subordinate to and distinct in essence from God the Father. Some 300 bishops, many of them scarred survivors of the persecutions that had ended only a decade earlier, gathered to settle the question.

The council overwhelmingly rejected Arius's teaching and produced the Nicene Creed, affirming that the Son is "true God from true God, begotten, not made, of one substance (homoousios) with the Father" - language chosen precisely to rule out any reading that made Christ a lesser, created deity. This was not an invention of new doctrine but a formal, careful articulation of what the church had confessed from its earliest days on the basis of texts like John's prologue ("the Word was God," John 1:1) and Paul's hymn to Christ in Colossians 1:15-20, now defended with philosophical precision against a serious and popular distortion.

Nicaea did not end the controversy overnight - the Arian dispute continued for decades, and a fuller form of the creed was finalized at the Council of Constantinople in AD 381 - but it stands as the church's first ecumenical council and its first great, unified defense of the full deity of Christ against denial from within its own ranks. For evangelicals today, Nicaea is a reminder that the church's core Christological convictions were not late developments but the settled conviction of Christians, rooted in Scripture rather than manufactured centuries after it.
