Why the Second Council Matters — Even for Us Today

Why the Second Council Matters — Even for Us Today

You’ve probably heard of the Nicene Creed—the prayer we say every Sunday in church that begins, “I believe in one God…” But did you know that the version we say today was finalized at the Second Ecumenical Council held in Constantinople in 381 AD?

This council was a turning point for the Church, and its decisions still shape our faith today.

What Was Going On?

The early Church was dealing with serious confusion. One major issue was a false teaching called Arianism, which claimed that Jesus wasn’t truly God. At the same time, some people were denying that the Holy Spirit was divine.

To protect the truth and unite the Church, the bishops gathered once more in council, praying and debating to clarify what the Church had always believed.

What Did the Council Do?

Affirmed the Divinity of the Holy Spirit

The Council clearly declared that the Holy Spirit is not a mere force or created being, but fully God, equal with the Father and the Son.

Completed the Creed

They expanded the Creed written at the First Council (Nicea, 325 AD) to include a section on the Holy Spirit, the Church, baptism, and eternal life. This became the Creed we still recite every Sunday.

Strengthened the Unity of the Church

By clarifying these core beliefs, the Council protected the Church from confusion and division.

Why It Matters Today

This is your faith: The truths protected at this Council are the same ones you profess each time you say the Creed. You stand in the same tradition as the saints and martyrs who lived it.

Truth still matters: In a world full of uncertainty, the Church continues to proclaim the truth with clarity and conviction.

You are not alone: The Holy Spirit, whom the Council proclaimed as God, lives in you, guiding, strengthening, and sanctifying you through the Church.

How to Respond

Next time you say the Creed, say it with awareness. These are not just ancient words—they are a declaration of your place in the Body of Christ, and a reminder that the Holy Spirit, the Lord and Giver of Life, is at work in you today.
