Commentary Compass

Ephesians is sometimes treated as though its first three chapters contain theology and its final three contain application. That division is convenient, but the strongest commentaries show that it misses the letter’s extraordinary coherence. Ephesians moves from God’s eternal purpose in Christ to the daily speech of Christians, from the reconciliation of heaven and earth to reconciliation between Jews and Gentiles, from Christ’s exaltation over cosmic powers to the way husbands, wives, children, parents, slaves and masters use power inside ordinary households. Its ethics are not appended to its theology. They are what its theology looks like when a new humanity begins living inside the old world.

S. M. Baugh is especially strong on the letter’s historical setting, Greek syntax, Old Testament backgrounds and the intricate connections between its individual passages. Constantine Campbell repeatedly clarifies discourse and the corporate nature of the church, while Clinton Arnold is particularly valuable on powers, spiritual warfare and the Ephesian religious environment. Frank Thielman brings careful exegesis into unusually balanced theological synthesis. Andrew Lincoln and Ernest Best remain indispensable critical conversation partners, Stephen Fowl is especially stimulating on theological interpretation and ecclesial formation, and Lynn Cohick and David deSilva bring fresh attention to the social world, identity and relationships addressed by the letter.

Read together, these commentators reveal that Ephesians is fundamentally about God creating unity in Christ on a scale much larger than personal salvation. Individuals are redeemed, forgiven, adopted and raised with Christ, but those gifts belong inside a larger purpose: God intends to bring all things in heaven and earth together under Christ. The church becomes an advance sign of that future because people once divided by covenant status, ethnicity and hostility are made into one new humanity and one temple in which God dwells by the Spirit. That reconciled community then becomes a display of divine wisdom even to the powers in the heavenly realms.

The governing movement can therefore be stated like this:

God’s purpose is to unite all things in Christ, and the church is where that future begins becoming visible now—in worship, reconciliation, maturity, holiness, household relationships and resistance to the powers that oppose God’s peace.

Here are twelve insights that make Ephesians clearer.

1. Ephesians Begins With Worship Because Salvation Begins in God’s Purpose Before It Becomes Our Experience

Ephesians 1:3–14 is one enormous outpouring of praise.

Before Paul tells Christians what to do, he blesses God for what God has already done.

God has blessed believers in Christ.

Chosen them in Christ.

Destined them for adoption through Christ.

Redeemed and forgiven them through Christ.

Revealed his purpose in Christ.

Given them an inheritance in Christ.

Sealed them with the promised Holy Spirit.

The repeated phrase “in Christ” or its equivalents is more important than any attempt to divide the paragraph into a mechanical list of separate benefits.

Everything comes through relationship with Christ.

Cohick rightly emphasises how the passage is surrounded by praise. The purpose of salvation is repeatedly described as “the praise of his glory.” Redemption therefore does not terminate upon the redeemed person.

It returns in worship toward the God whose grace produced it.

This gives Ephesians an important order.

Grace precedes command.

Identity precedes conduct.

Divine action precedes human response.

When the ethical exhortations begin in chapter 4, Paul will say, “therefore, walk worthy of the calling you have received.” The “therefore” rests upon three chapters of divine action.

Christian ethics is therefore not an attempt to construct an identity that God might later reward.

It is the attempt to live appropriately inside an identity grace has already given.

That is why Ephesians begins with praise rather than anxiety.

The first word over Christian existence is not:

“Achieve.”

It is:

“Blessed be God, who has blessed us in Christ.”

2. Election in Ephesians Is Always “in Christ” and Always Directed Toward a Holy People

Few passages have generated more theological debate than Ephesians 1:4–5:

God chose us in Christ before the foundation of the world and predestined us for adoption.

Readers naturally ask how this relates to divine sovereignty, human freedom, individual election and the sequence of salvation.

Those questions are legitimate, but they can easily become so dominant that Paul’s explicit emphases disappear.

First, the election is repeatedly located in Christ.

Paul does not invite readers to speculate about an abstract decree detached from Jesus. God’s eternal purpose and the historical work of Christ belong together.

Second, election has a stated goal:

that God’s people should be holy and blameless before him.

Third, predestination is described as adoption.

The language is therefore relational before it is merely classificatory.

God’s purpose is to create a family.

Fourth, the whole passage culminates repeatedly in praise.

Election is meant to generate worship and holiness, not superiority.

This becomes especially important once Ephesians reaches the relationship between Jews and Gentiles. A doctrine of election that produces ethnic or spiritual boasting would contradict the very reconciliation the letter celebrates.

The chosen people are chosen in the Chosen One.

They are adopted through the Son.

And the family being formed turns out to include people who once stood far outside Israel’s covenant privileges.

Ephesians therefore directs theological reflection away from the question:

How can I use election to establish my superior status?

and toward:

What kind of holy, reconciled and worshipping people did God intend to create when he chose us in Christ?

3. God’s Great Plan Is Not Merely to Save Individuals but to Bring All Things Together in Christ

Ephesians 1:9–10 gives the letter its largest horizon.

God has revealed the mystery of his will, a plan for the fullness of the times:

to bring together, sum up or unite all things in Christ, things in heaven and things on earth.

This is much larger than the salvation of isolated souls.

Sin has produced alienation in multiple dimensions.

Human beings are alienated from God.

Jews and Gentiles are divided.

Human communities fragment.

Hostile powers operate in the heavenly realm.

Creation itself stands in disorder.

God’s purpose in Christ reaches across the whole fractured field.

This does not mean Ephesians teaches a universalism in which every creature ultimately experiences salvation in precisely the same way. Later passages still speak of judgment, evil powers and opposition.

The point is rather that nothing will remain permanently outside Christ’s rightful ordering of creation.

All things will ultimately find their proper relation under him.

This gives the church extraordinary significance.

The church does not accomplish the cosmic reconciliation itself.

Christ does.

But the church becomes the place where that future begins appearing before the end.

Jew and Gentile become one.

Former enemies receive one access to the Father.

Different gifts serve one body.

Household power comes under one Lord.

Believers resist spiritual powers while wearing God’s armour.

Ephesians therefore moves constantly between enormous theological horizons and ordinary communal life because those two scales belong together.

If God intends to unite all things in Christ, then a Christian community learning to live in peace is not a small side issue.

It is a local preview of the future of creation.

4. The Power Christians Need Is the Same Power Displayed When God Raised and Exalted Christ

Paul’s first great prayer in Ephesians does not mainly ask that believers receive more power.

It asks that the eyes of their hearts be enlightened so they can know the immeasurable greatness of the power already at work toward them.

Paul then defines the power.

It is the power God exercised when he raised Christ from the dead, seated him in the heavenly realms and placed him above every rule, authority, power, dominion and name.

This matters especially in a world where people feared visible and invisible powers.

Arnold’s work has rightly drawn sustained attention to this dimension of Ephesians. The letter assumes that spiritual powers are real enough to matter, but Christ’s relationship to them is never one of uncertainty.

He is above them.

Not barely.

Not temporarily.

Not after a close contest.

Far above every competing authority.

Then Ephesians 2 makes an astonishing move.

Believers who were dead are made alive with Christ, raised with Christ and seated with Christ in the heavenly realms.

The exaltation described in chapter 1 therefore becomes the location of Christian identity in chapter 2.

This does not mean Christians are already physically resurrected or presently exercise unrestricted cosmic rule.

It means their life is inseparably joined to the victorious Christ.

The powers may threaten.

The church may appear socially insignificant.

Paul himself can write from imprisonment.

Yet the ultimate spiritual location of believers is determined not by the power presently visible around them but by the Christ with whom they are united.

That prepares for Ephesians 6.

Christians do not put on armour in order to win the cosmic victory Christ failed to secure.

They stand because the victorious Christ has already determined the outcome.

5. “By Grace You Have Been Saved” Leads Directly to “Created for Good Works”

Ephesians 2:1–10 gives one of Paul’s clearest descriptions of salvation.

The starting condition is not moral weakness.

It is death.

People walk according to the age of this world, the ruler of the power of the air and the desires of the flesh.

Then come perhaps the two most important words in the paragraph:

“But God…”

God acts because he is rich in mercy and great in love.

The dead are made alive with Christ.

Salvation is by grace.

Paul then states the point unmistakably: salvation is not from ourselves and not from works, so no one can boast.

But Ephesians does not oppose grace to moral transformation.

Immediately after excluding works as the basis of salvation, Paul restores works as the purpose of the recreated life.

Believers are God’s workmanship, created in Christ Jesus for good works that God prepared beforehand for them to walk in.

The symmetry is beautiful.

Once they walked in trespasses and sins.

Now they are created to walk in good works.

Grace changes the path.

This prevents two opposite mistakes.

The first makes good works the means by which people earn God’s saving favour.

Paul excludes that.

The second receives grace as though salvation leaves the direction of life unchanged.

Paul excludes that too.

Grace is free.

And grace is creative.

God does not discover morally successful people and reward them with salvation.

He raises the dead and creates a people capable of walking differently.

6. “Christ Is Our Peace” Means Reconciliation Is More Than Tolerating Difference

Ephesians 2:11–22 is one of the New Testament’s greatest passages on reconciliation.

Gentile readers are told to remember what their former position actually was.

They were separated from Christ.

Alienated from the commonwealth of Israel.

Strangers to the covenants of promise.

Without hope and without God in the world.

Then comes another great reversal:

“But now in Christ Jesus…”

Those who were far away have been brought near through Christ’s blood.

Paul does not merely say Christ makes peace.

He says:

Christ is our peace.

Jew and Gentile are reconciled through the cross, hostility is killed and the two are created into one new humanity in Christ.

Campbell is especially helpful in showing the corporate force of the image. The new humanity is not simply a club containing two types of members who remain fundamentally separated. The two are incorporated into one new person in Christ.

Yet unity does not require pretending history never existed.

Paul explicitly tells Gentiles to remember their previous distance from Israel’s covenant privileges. Reconciliation is not achieved by erasing Israel’s story or pretending Jew and Gentile were always interchangeable categories.

The miracle is precisely that people genuinely separated by covenant history are brought together.

Nor does the passage simply describe Gentiles being absorbed into Jewish ethnicity.

Both are reconciled to God through the cross and recreated in Christ.

This makes Christian peace much thicker than civility.

Paul does not envision former enemies agreeing to stop fighting while retaining social worlds that never really meet.

They become one body.

Peace is therefore not merely absence of hostility.

It is shared belonging created by Christ.

7. The New Humanity Does Not Merely Enter the Temple—It Becomes the Temple

The final movement of Ephesians 2 is easy to overlook because the reconciliation language is already so powerful.

Paul changes metaphors.

Gentiles were once strangers and aliens.

Now they are fellow citizens and members of God’s household.

Then the household becomes a building.

Apostles and prophets form the foundation, Christ Jesus is the cornerstone, the whole structure grows into a holy temple, and believers are being built together into a dwelling place of God by the Spirit.

This is an extraordinary development in biblical temple theology.

The dividing wall has lost its power.

Those once excluded from privileged access are not merely permitted farther inside the old structure.

Together they become the new structure in which God dwells.

The temple is therefore inseparable from reconciliation.

God’s dwelling place is built out of people whom hostility once kept apart.

This means unity in Ephesians is not simply an organisational priority because divided churches function poorly.

The church’s unity belongs to its identity as temple.

To fracture the reconciled community is to contradict the architecture of God’s dwelling.

The passage is also profoundly trinitarian.

Through Christ, both groups have access in one Spirit to the Father.

The church exists through the work of Father, Son and Spirit, and the result is a people in whom divine presence dwells.

This helps explain why later ethical instructions are so serious.

Truthful speech, forgiveness, sexual holiness, generosity and love are not merely rules for respectable individuals.

They are practices appropriate to a temple made of people.

8. The “Mystery” Is That Gentiles Are Full Coheirs—and the Reconciled Church Teaches the Powers About God

Ephesians speaks repeatedly about a “mystery,” but the mystery is not an esoteric technique disclosed only to advanced Christians.

Paul tells us what it is.

Gentiles are coheirs, members of the same body and coparticipants in the promise in Christ through the gospel.

The intensity of the compound language matters.

Gentiles have not been admitted as a second-tier group standing at the edges of Israel’s hope.

They share fully.

Paul’s ministry consists in announcing the unsearchable riches of Christ among the nations and making known this previously hidden divine purpose.

Then Ephesians makes an astonishing claim in 3:10.

Through the church, God’s manifold wisdom is now being made known to rulers and authorities in the heavenly realms.

The church therefore has a cosmic audience.

God could announce his wisdom directly.

Instead, he shows it.

Jews and Gentiles worshipping together become an enacted demonstration that the reconciling plan of God is working.

This makes the church’s diversity and unity spiritually significant on a scale Christians rarely imagine.

A reconciled congregation is not merely useful evidence for outsiders that Christianity produces friendliness.

It is a theological statement addressed even to the powers.

The church says:

Christ’s cross has created something the powers of division could not create.

Hostility is not ultimate.

Ethnic alienation is not ultimate.

The structures by which human beings rank and exclude one another do not determine the future.

God’s wisdom does.

Ephesians 3 therefore turns ecclesiology into cosmic witness.

The church teaches by existing as the reconciled people Christ created.

9. “Know the Love That Surpasses Knowledge” Is Paul’s Answer to Spiritual Fullness

Paul’s second great prayer, in Ephesians 3:14–21, moves from strength to indwelling, from indwelling to love and from love toward fullness.

He prays that believers will be strengthened through the Spirit in the inner person so that Christ may dwell in their hearts through faith.

Then, rooted and grounded in love, they are to comprehend with all the saints the breadth, length, height and depth and to know the love of Christ that surpasses knowledge.

The paradox is deliberate.

They must know what exceeds knowing.

Christian maturity therefore does not mean reaching the point where divine love has been intellectually mastered.

The more deeply it is known, the more clearly its immeasurability appears.

Notice also the communal setting.

Paul does not imagine one spiritual virtuoso ascending alone into extraordinary mystical knowledge.

The dimensions of Christ’s love are comprehended with all the saints.

The community itself becomes part of the way Christians learn the love of Christ.

Then comes the climax:

that they may be filled to all the fullness of God.

This is astonishing language, but the preceding movement tells us what fullness looks like.

It is not escape from creaturehood.

Not elite status.

Not possession of secret information.

The fullness of God is approached through the indwelling Christ, the strengthening Spirit and an ever-deepening grasp of Christ’s immeasurable love.

The prayer therefore anticipates chapter 4, where the whole body grows toward the measure of Christ’s fullness.

Fullness is corporate maturity in Christ.

Ephesians answers spiritual ambition not by lowering the ambition but by redirecting it.

There is indeed more to know.

More to experience.

More fullness into which to grow.

But the inexhaustible “more” is found inside the love of Christ, not beyond Christ.

10. The Church’s Leaders Are Gifts to Equip the Whole Church for Ministry

Ephesians 4 begins the letter’s great ethical movement with an appeal to walk worthy of the calling already described.

The first concern is unity.

Humility.

Gentleness.

Patience.

Bearing with one another in love.

Eagerly maintaining the unity of the Spirit in the bond of peace.

Paul then gives a magnificent series of “ones”:

one body,

one Spirit,

one hope,

one Lord,

one faith,

one baptism,

one God and Father.

The church does not manufacture this unity.

It receives it.

The command is to maintain the unity the Spirit has already created.

Yet unity does not mean uniformity.

Christ gives different gifts: apostles, prophets, evangelists, pastors and teachers.

The purpose of these gifted people becomes especially significant in 4:12. Campbell strongly supports the interpretation that they equip the saints for the work of ministry, so that the body of Christ is built up.

On this reading, ministry does not belong primarily to a professional clerical class while ordinary Christians receive religious services.

Leaders equip.

The saints minister.

The whole body grows.

Ephesians 4:16 makes the conclusion difficult to avoid: the body grows as each individual part does its work.

This produces a powerful vision of church leadership.

Leaders are important precisely because the ministry does not terminate upon them.

Their success is measured partly by whether the body itself becomes capable of truth, service, love and maturity.

The goal is not dependence upon gifted personalities.

It is a community no longer tossed around by every teaching but growing into Christ the Head.

Christian maturity is therefore irreducibly corporate.

No member becomes fully mature by becoming unnecessary to everyone else.

The body grows together.

11. Putting On the New Humanity Eventually Changes Speech, Work, Worship, Marriage and Household Power

Ephesians 4:17 begins to describe what the new humanity of chapter 2 actually looks like.

Paul contrasts an old way of life characterised by darkened understanding, alienation and distorted desire with a new humanity created according to God in righteousness and holiness.

The language of “putting off” and “putting on” is therefore larger than private self-improvement.

As Muddiman and others note, the imagery has a strongly corporate dimension. Christians belong to a new kind of humanity and must stop living according to the patterns of the old.

Paul immediately becomes practical.

Stop lying and speak truth because we are members of one another.

Anger must not become an opportunity for the devil.

The thief must not merely stop stealing but work so that there is something to share with those in need.

Destructive speech must become speech that builds up.

Bitterness, rage and malice give way to kindness and forgiveness because God has forgiven believers in Christ.

The same movement continues through chapter 5.

Christians walk in love because Christ loved and gave himself.

They walk as light.

They walk wisely.

Then Paul commands them to be filled with the Spirit.

What does Spirit-filling look like?

Singing.

Speaking to one another through psalms, hymns and spiritual songs.

Thanksgiving.

And relationships characterised by submission under Christ.

The household material that follows is difficult and has generated substantial debate, especially regarding gender and the extent to which ancient household structures should be reproduced today. It should neither be dismissed nor treated as though Paul simply baptises Greco-Roman hierarchy unchanged.

The governing example given to husbands is startling:

Christ loved the church and gave himself for her.

Campbell and Cohick rightly stress how demanding this is. The husband is never commanded to enforce his wife’s submission. He is commanded to love according to a cruciform pattern of self-giving.

The social direction continues with children and parents, slaves and masters. Masters eventually discover that they themselves have a Master in heaven and that he shows no partiality.

Ephesians therefore brings the lordship of Christ into every asymmetrical relationship.

The question becomes:

What happens to ordinary human power when the person who possesses it must imitate the One who gave himself away?

12. The Armour of God Is God’s Own Armour—and Christians Are Told Primarily to Stand

Ephesians ends where many ancient Christians in a city such as Ephesus may have felt the problem most acutely: spiritual conflict.

Paul says the struggle is not ultimately against flesh and blood but against rulers, authorities and spiritual forces of evil.

That warning can produce fear if detached from the rest of the letter.

But Ephesians has already told us:

Christ is exalted above every ruler and authority.

Believers have been raised and seated with him.

The church displays God’s wisdom to the powers.

The final call to spiritual warfare therefore comes after the victory of Christ has been established.

Christians are told to be strengthened in the Lord and put on the whole armour of God.

The Old Testament background is especially important. Isaiah portrays YHWH and his messianic servant as the Divine Warrior clothed with righteousness and salvation.

Paul is therefore not merely using a Roman soldier as a convenient sermon illustration.

Believers are being clothed with God’s own battle equipment:

truth,

righteousness,

the gospel of peace,

faith,

salvation,

the word of God.

Notice how closely these correspond to realities the letter has already described.

Spiritual warfare is therefore not primarily fascination with identifying demons, mapping territorial spirits or discovering specialised techniques.

It is persevering in the gospel-shaped life God has already given.

Truth resists the father of lies.

Righteousness resists corruption.

Peace resists division.

Faith extinguishes accusation.

Salvation secures identity.

The word of God answers deception.

And the whole armour is surrounded by prayer.

The repeated command is to stand.

Believers are not told to conquer a territory Christ has failed to win.

They withstand.

Remain.

Persevere.

Ephesians ends spiritual warfare where it began Christian existence:

in the strength supplied by God rather than in autonomous human power.

What Ephesians Finally Teaches About the Church

The twelve insights reveal that Ephesians possesses one of the largest visions of the church anywhere in Scripture.

The church is not merely an association of forgiven individuals.

It is the body of the exalted Christ.

The new humanity created through the cross.

The household of God.

The temple in which God dwells through the Spirit.

The community through which divine wisdom is displayed to cosmic powers.

The body growing toward the fullness of Christ.

The bride for whom Christ gives himself.

The community standing in God’s armour against spiritual evil.

Every image adds something.

Body emphasises relation to Christ the Head and interdependence among members.

New humanity emphasises reconciliation across old divisions.

Household emphasises belonging.

Temple emphasises divine presence.

Bride emphasises covenant love.

Army imagery emphasises resistance.

None should be allowed to erase the others.

The result is an ecclesiology too large for churches to think of themselves primarily as providers of religious goods to individual consumers.

God’s cosmic purpose is being rehearsed there.

That makes unity both gift and calling.

The church does not create the reconciliation accomplished by the cross.

But it can either display that reconciliation or contradict it.

The church does not defeat the powers.

Christ has triumphed.

But a congregation governed by hostility, falsehood, domination and division can live as though those powers still possess the final word.

Perhaps the deepest lesson of Ephesians can therefore be stated like this:

Ephesians teaches that God’s purpose in Christ is to heal the fractures of creation, and the church becomes credible when the reconciliation already accomplished by Christ begins taking visible form in a people who worship together, grow together, speak truthfully, forgive one another, use power sacrificially and stand together against everything that would divide what Christ has made one.

Ephesians Within the Larger Biblical Story

Ephesians draws together an extraordinary range of biblical trajectories.

Creation stands behind God’s purpose formed before the foundation of the world and his plan to unite all things in Christ.

Abraham and Israel stand behind the language of promise, covenant, inheritance and Gentile distance from the commonwealth of Israel.

Exodus imagery resonates in redemption and deliverance.

Temple theology becomes explicit when Jew and Gentile are built together as the dwelling of God through the Spirit.

Adam and new-creation theology stand behind the old humanity and new humanity language.

The Psalms contribute to the picture of the ascended Christ giving gifts to his people.

Isaiah contributes peace, new creation and especially the armour of the Divine Warrior.

The biblical story therefore does not disappear when Gentiles enter.

Gentile inclusion is astonishing precisely because Israel’s covenant story remains the story into which they are brought near through Israel’s Messiah.

This is why Ephesians 2 must not become a licence for Christian contempt toward Judaism. Gentiles are explicitly commanded to remember that they were once strangers to Israel’s covenant promises.

Their inclusion is grace.

The cross does not establish Gentile superiority over Jews.

It kills hostility and creates one new humanity.

Ephesians’ temple theology then carries the biblical trajectory forward dramatically. God once dwelt in the tabernacle and temple. Now a reconciled people, built around Christ and indwelt by the Spirit, becomes the dwelling place.

Its kingdom theology is similarly expansive. Christ sits above all powers, and God’s plan ultimately encompasses everything in heaven and earth.

The New Testament’s final vision in Revelation therefore resonates naturally with Ephesians: hostile powers are defeated, God dwells with his people and creation comes under the uncontested reign of God and the Lamb.

Yet Ephesians insists that Christians need not wait until the end to begin embodying that future.

Every act of reconciliation anticipates it.

Every truthful word anticipates it.

Every act of forgiveness anticipates it.

Every community in which people of different backgrounds genuinely become one anticipates it.

Every use of authority shaped by Christ’s self-giving love anticipates it.

Every refusal to answer spiritual evil with flesh-and-blood hatred anticipates it.

That is why Ephesians can begin before the foundation of the world, rise into the heavenly realms, descend into kitchens and households, and finish amid cosmic warfare without ever changing subjects.

The subject throughout is the same:

what God is doing in Christ to create a world made whole.
