Defining the Faith: Nicaea

Today's Reading

In AD 325, approximately 300 bishops traveled from across the Roman Empire to the lakeside town of Nicaea in modern-day Turkey. They came at the invitation of Emperor Constantine to settle a question that was tearing the church apart: Who is Jesus Christ?

The crisis had been triggered by a charismatic priest from Alexandria named Arius. His teaching was elegant and logical: if the Son was "begotten" by the Father, then there must have been a time when the Son did not exist. "There was when the Son was not," Arius taught (Thalia, as recorded in Athanasius, De Synodis, Chapter 15). Jesus was the highest of all creatures — divine in some sense — but not God in the same way the Father was God.

The implications were enormous. If Jesus was a created being, then Christians were worshipping a creature. If he was less than fully God, then his death on the cross could not accomplish what the church claimed: the reconciliation of God and humanity. Everything depended on the answer to Jesus's own question.

Biblical Connection

At Caesarea Philippi, Jesus had asked his disciples: "Who do you say that I am?" Peter answered: "You are the Christ, the Son of the living God" (Matthew 16:15–16). That answer — not a philosophical category, but a confession of identity — is the foundation stone of Christian faith.

Paul, writing to the Colossians, gave the fullest expression of what was at stake: "He is the image of the invisible God, the firstborn of all creation. For by him all things were created, in heaven and on earth, visible and invisible... He is before all things, and in him all things hold together" (Colossians 1:15–17). The Christ of Colossians is not a creature. He is the Creator.

Going Deeper

The Council of Nicaea, after weeks of debate, sided decisively against Arius. The creed they produced declared that the Son is "of one substance" (homoousios) with the Father — "God of God, Light of Light, true God of true God, begotten, not made." This was not an invention. It was an attempt to state clearly what Scripture taught and what the church had always worshipped.

Irenaeus, writing over a century before Nicaea, had already grasped what was at stake: "He became what we are so that He might make us what He is" (Against Heresies, Book 5, Preface). If Christ is not truly God, he cannot save. If he is not truly human, he cannot represent us. The creed was not an academic exercise. It was the church drawing a line around the gospel itself.

The Nicene Creed remains, to this day, the most widely accepted statement of Christian belief — confessed by Catholic, Orthodox, and Protestant churches alike. It endures because the question endures: Who is Jesus? Everything depends on the answer.
