Unpacking Ephesians 4:3-6: One Faith, One Family

Context and Flow of Ephesians 4:3-6

Having urged believers to live in a way that honors their calling, Paul now calls them to preserve the unity the Spirit has already created.

This passage comes right after Paul’s call to humility, gentleness, and patience in verse 2, all of which are essential for maintaining unity. He grounds this unity not in our efforts but in seven divine realities: one body, one Spirit, one hope, one Lord, one faith, one baptism, and one God over all. These 'ones' are not goals to achieve but truths to live out, rooted in what God has already done.

From here, Paul will go on to explain how grace is given to each believer for the purpose of building up that same unity in maturity and love.

The Seven 'Ones' and the Foundation of Christian Unity

The seven 'ones' in Ephesians 4:4-6 are a carefully structured confession that roots Christian unity in the nature of God and His redemptive work.

These 'ones' form a theological framework. 'One body' refers to the church as Christ’s people, united across all divisions. 'One Spirit' points to the Holy Spirit who indwells every believer and binds them together, as seen in 1 Corinthians 12:13 where Paul says we are 'all baptized by one Spirit into one body'. 'One hope' looks forward to the future resurrection and eternal life promised to all believers, a hope grounded in God’s sure promise rather than optimism.

The triad of 'one Lord, one faith, one baptism' connects personal commitment with shared practice. 'One Lord' (Jesus) affirms His exclusive authority in a world of competing loyalties. 'One faith' means the common trust in Christ shared by all believers, rather than a vague religious feeling. 'One baptism' signifies the public, unifying act of joining Christ’s people, rather than a mere ritual.

The climax is 'one God and Father of all, who is over all and through all and in all' - a Trinitarian-like affirmation that echoes the Shema of Deuteronomy 6:4 but expands it through the lens of Christ’s work; this God is sovereign ('over all'), active ('through all'), and personally present ('in all'), holding everything together.

Christian unity isn't built on agreement in opinions, but on the unchanging realities of who God is and what He has done.

This unity is not something we manufacture but a reality we are called to preserve. The next section will show how God gives different gifts to different people, not to divide but to build up this same unified body in love.

Living Out Unity in Everyday Relationships

The call to 'make every effort to keep the unity of the Spirit' is not a vague ideal but a daily choice to prioritize peace in our relationships.

For the original readers - Christians in a diverse city like Ephesus - this was radical: Jews and Gentiles, slaves and free, all treating each other as equals in one family. This unity reflects the gospel itself: just as Christ broke down the wall between us and God, He also breaks down the walls between us.

Keeping unity isn’t about agreeing on everything - it’s about choosing love and peace when differences arise.

And this effort to stay united isn’t a burden - it’s how we grow. The next verses show that God gives each of us different gifts, not to highlight our differences, but to help the whole group become stronger together in love.

Unity in the Body: A Witness to the World

This Spirit-led unity is meant to be a visible testimony to the world, as Jesus prayed in John 17:20-23.

In that prayer, Jesus said, 'I do not ask for these only, but also for those who will believe in me through their word, that they may all be one, even as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me.' Similarly, Paul writes in Galatians 3:28, 'There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus,' showing that our deepest identity is no longer in our differences but in Him.

When believers truly live in unity, the world begins to see a glimpse of God’s love and power.

The next section will explore how God equips each believer with unique gifts, not to stand out on their own, but to serve others and strengthen this same unified body.
