What is the Mystery in Ephesians?
Quick Summary
The word mystery appears throughout Ephesians as a way of describing God’s long‑hidden plan now revealed in Christ. The mystery is not a secret code or hidden knowledge. It is the good news that God is bringing Jew and Gentile together into one family through Jesus, creating a new humanity and a reconciled people. Paul uses the word to help the church understand its identity, its purpose, and the grace that makes it possible.
Introduction: Hearing the Word Mystery in Ephesians
I owe my understanding and appreciation of “mystery” to my New Testament and Greek professor, the late Dr. Douglas Bain. He methodically taught us that this “mystery” is also an “open secret.” It is our job as Christians to speak the secret so that others may know the blessings we have in Christ.
When Paul uses the word mystery, he is not talking about something puzzling or strange. He is talking about something God held in place until the time was right. The mystery is a story that was once hidden but is now open for the world to see. It is the full scope of God’s work through Christ, gathering people into a unified family.
This theme rises again and again throughout the letter. The fullness of the mystery becomes clear when read alongside the unity described in Ephesians 4:1-16, the reconciliation in Ephesians 2:11-22, and the calling of Paul described in Ephesians 3:1-13.
The Mystery Revealed: Jew and Gentile United in Christ
Paul explains that the mystery centers on unity. God is forming one reconciled people through Christ, bringing together groups that once lived separately. The wall between them comes down. This can be seen clearly in Ephesians 2:14-18, where Christ himself becomes our peace.
This unity was not a last‑minute idea. It had always been part of God’s intention. What was hidden is now visible. Paul calls it a mystery because people could not fully see it until Christ came. Now the church is the living picture of God’s reconciling work.
The Mystery and Paul’s Calling
Paul speaks of his own life as a witness to the mystery. In Ephesians 3:1-7, Paul describes being entrusted with the grace to proclaim this good news. His calling is not only to announce it but to embody it.
The more the reader sits with Paul’s language in Ephesians 3, the more the generosity of God becomes clear. Paul sees himself as a servant of a story larger than he ever expected. The mystery reveals the vastness of God’s mercy, the reach of God’s grace, and the depth of God’s plan.
The Church as the Display of the Mystery
Paul writes that the church becomes the living demonstration of God’s wisdom. In Christ, a new humanity appears where hostility once ruled. The unity described in Ephesians 4:13-16 flows directly from the mystery revealed.
When the church lives in this unity, it becomes a witness to the world. The grace described in Ephesians 2:4-7 becomes tangible. The reconciliation shines in a way that can be seen and felt.
The Mystery and Spiritual Strength
Paul moves from describing the mystery to praying that believers would have the strength to grasp it. His prayer in Ephesians 3:14-21 invites readers to rest in God’s love. The mystery is not only something to understand. It is something to experience.
This love gives shape to Christian life. It gives courage to walk in the unity described in chapter four and wisdom to live out the calling described in Ephesians 5:1-20.
Why the Mystery Matters Today
Paul’s language still speaks to the world we live in. The church continues to live in places marked by division and competition. The mystery reminds believers that reconciliation is God’s work and God’s desire. The call to unity is not merely a moral task. It flows from the heart of the gospel.
The mystery reshapes how the church sees itself. It invites believers to move toward one another with humility, patience, and love. It encourages a life formed by grace and sustained by the Spirit.
