Paul's Letter to the Ephesians: Author, Context and Complete Study

Ephesians celebrates the spiritual blessings God has given his people in Christ and reveals his plan to unite all things in him, beginning with one church made of Jews and Gentiles. It then calls believers to walk worthy of that calling, in unity, holiness, love, family life and spiritual warfare.

What is Ephesians about?

Ephesians is about what God has done for his people in Christ and how they should live as a result. In chapters 1-3 Paul praises God for choosing, redeeming and sealing believers (Ephesians 1:3-14), shows that sinners dead in their sins are saved by grace through faith (2:1-10) and reveals that Jews and Gentiles are now one body (2:11-3:13). In chapters 4-6 he calls them to walk worthy of that calling: to keep the unity of the Spirit, put on the new self, live in love and light, honor Christ at home and stand firm in the armor of God (4:1; 6:10-18).

Author: The apostle Paul, who names himself twice and writes as a prisoner (Ephesians 1:1; 3:1). Tradition is unanimous; some modern scholars think a disciple wrote it in his name, while many defend Paul's authorship.
Date: c. AD 60-62, during Paul's imprisonment, most likely in Rome (some suggest Caesarea or Ephesus).
First readers: Believers in Ephesus and probably other churches of the province of Asia, mostly Gentiles, called to understand their new identity in Christ and to live in unity with Jewish believers.
Genre: Letter
Chapters: 6 chapters
Key verse: Ephesians 2:8-10

Historical context

Paul wrote Ephesians as a prisoner (3:1; 4:1), an ambassador in chains (6:20). Most interpreters place it during his house arrest in Rome, c. AD 60-62, when he waited two years for his case and welcomed everyone who came to him (Acts 28:30-31). Nero was emperor. Ephesians belongs with Colossians and Philemon: all three mention Tychicus, who carried the letters (Ephesians 6:21-22; Colossians 4:7-9), and Ephesians and Colossians share much of their language. Together with Philippians, they are known as the Prison Letters.

Paul knew Ephesus well. He stopped there briefly with Priscilla and Aquila (Acts 18:19-21) and returned for his longest stay anywhere, about three years (Acts 20:31), teaching first in the synagogue and then for two years in the hall of Tyrannus, so that people throughout the province of Asia heard the word (Acts 19:8-10). Magic books worth fifty thousand pieces of silver were burned, and the silversmith Demetrius stirred up a riot in defense of the goddess Artemis (Acts 19:19, 23-41). Later Paul said farewell to the Ephesian elders at Miletus (Acts 20:17-38). The churches of the region were young and mostly Gentile, surrounded by idolatry and occult practices, and Jewish and Gentile believers had to learn to live as one people.

Geographical context

Ephesus, near the western coast of Asia Minor (today near Selcuk, Turkey), was the leading city of the Roman province of Asia and one of the largest cities of the eastern empire. It had a busy harbor, a great theater where the crowd rioted against Paul (Acts 19:29) and the temple of Artemis, counted among the seven wonders of the ancient world. Roads ran from Ephesus up the river valleys to cities such as Laodicea, Colossae and Hierapolis, and the gospel spread along them during Paul's stay (Acts 19:10).

Paul's place of writing was probably Rome, the capital of the empire. The letter itself, however, is less tied to places than any other letter of Paul: its horizon is the heavenly places, where Christ is enthroned and where the spiritual battle is fought (1:3, 20; 6:12).

Why does the book of Ephesians exist?

Ephesians has no specific crisis behind it, no false teacher named and no dispute to settle, which is why many read it as a circular letter meant for several churches. Its purpose is to help believers grasp who they are in Christ. Many were Gentiles who had once been without hope and without God in the world (2:12) and lived among powerful idols and spiritual forces. Paul wants them to know the hope of God's calling, the riches of his inheritance and the immeasurable greatness of his power toward them (1:18-19), and to be rooted in the love of Christ (3:17-19).

The second aim is unity. God's plan is to unite all things in Christ (1:10), and the church, made of Jews and Gentiles reconciled in one body, is the first sign of that plan before the watching powers (2:14-16; 3:10). So Paul turns doctrine into practice: walk worthy of your calling (4:1), use your gifts to build up the body, put off the old life, love as Christ loved, let Christ shape marriage, parenting and work, and stand firm in God's strength against the devil (6:10-11). Ephesians gives the Bible's richest teaching on the church as the body, temple and bride of Christ.

Outline of Ephesians

Chapter 1
Every spiritual blessing in Christ
Paul praises the Father, who chose believers in Christ, the Son, in whom they have redemption through his blood, and the Spirit, with whom they are sealed. Then he prays that they may know their hope, their inheritance and God's power, shown in raising Christ and making him head over all things for the church.

Chapter 2
Made alive and made one
Once dead in sins, believers have been made alive with Christ and saved by grace through faith, as God's workmanship created for good works. Gentiles once far off have been brought near by Christ's blood; he broke down the dividing wall and made Jews and Gentiles one new people, a holy temple for God.

Chapter 3
The mystery revealed and a prayer for strength
Paul explains the mystery entrusted to him: through the gospel the Gentiles are fellow heirs and members of the same body. He prays that believers may be strengthened by the Spirit, grasp the dimensions of Christ's love and be filled with God's fullness, and he ends with a doxology.
- 3
Chapter 4
One body, many gifts, a new self
Believers must walk worthy of their calling and keep the unity of the Spirit, for there is one body, one Lord, one faith and one God. The risen Christ gives leaders to equip the saints so the body grows to maturity. They put off the old self and put on the new, speaking truth and forgiving as God forgave them.

Chapter 5
Walking in love, light and wisdom
As beloved children, believers imitate God and walk in love, avoid sexual immorality and darkness, live as children of light and make the best use of time. Filled with the Spirit, they sing, give thanks and submit to one another; marriage reflects the love of Christ for the church.
- 5
Chapter 6
Faithful at home and strong in the Lord
Children honor their parents, fathers bring children up in the Lord, and slaves and masters serve the same Master in heaven. Paul calls believers to put on the whole armor of God against the schemes of the devil, to pray at all times and to pray for him, and he sends Tychicus with news.

Famous passages in Ephesians

Ephesians 1:3-14
Every spiritual blessing
In one long sentence in the Greek, Paul praises God for blessing believers in Christ with every spiritual blessing: chosen before the foundation of the world, adopted, redeemed through Christ's blood, forgiven and sealed with the Holy Spirit as a guarantee of their inheritance. The refrain to the praise of his glory marks the work of Father, Son and Spirit.

Ephesians 2:8-10
Saved by grace through faith
Salvation is by grace through faith; it is not the result of works but the gift of God, so no one may boast. Yet believers are God's workmanship, created in Christ Jesus for good works that God prepared beforehand. These verses are among the clearest summaries of the gospel and show how grace and good works fit together.

Ephesians 2:14-16
Christ broke down the dividing wall
Christ himself is our peace. Through his death he broke down the wall of hostility between Jews and Gentiles, created one new humanity from the two and reconciled both to God in one body through the cross. The passage is a foundation for the unity of the church across every ethnic and cultural line.

Ephesians 3:14-21
Far more than we ask or think
Paul kneels before the Father and prays that believers may be strengthened by the Spirit, that Christ may dwell in their hearts through faith and that they may grasp the breadth, length, height and depth of a love that surpasses knowledge. He closes by praising the God who is able to do far more abundantly than all we ask or imagine.

Ephesians 4:11-16
Gifts to build up the body
The ascended Christ gave apostles, prophets, evangelists, shepherds and teachers to equip the saints for the work of ministry and build up his body.

Ephesians 5:22-33
Marriage and the love of Christ
Paul addresses wives and husbands in light of Christ and the church: wives are to submit to their husbands as to the Lord, and husbands are to love their wives as Christ loved the church and gave himself up for her. Quoting Genesis 2:24, he calls marriage a profound mystery that points to Christ and his church.

Ephesians 6:10-18
The armor of God
Believers are to be strong in the Lord and put on the whole armor of God, because their struggle is not against flesh and blood but against spiritual forces of evil. The belt of truth, the breastplate of righteousness, the shoes of the gospel of peace, the shield of faith, the helmet of salvation and the sword of the Spirit, the word of God, are joined to constant prayer.

Main themes

Blessed in Christ: Every blessing believers have comes in Christ: election, adoption, redemption, forgiveness, the seal of the Spirit and a seat with Christ in the heavenly places. The expressions in Christ and in him run through the letter like a refrain (1:3-14; 2:6).
Salvation by grace: Humanity was dead in trespasses and sins, following the ways of the world and the ruler of the power of the air. But God, rich in mercy, made sinners alive with Christ; salvation is his gift, received through faith, and leads to good works (2:1-10).
One new people: Through the cross Christ reconciled Jews and Gentiles to God and to each other. Gentiles are now fellow citizens with the saints, members of God's household and fellow heirs of the promise. This was the mystery hidden for ages and now revealed (2:11-3:6).
The church, body and bride of Christ: The church is Christ's body, of which he is the head, the holy temple where God dwells by the Spirit and the bride Christ loves and cleanses. Through the church the manifold wisdom of God is made known even to the heavenly powers (1:22-23; 2:21-22; 3:10; 5:25-27).
Walking worthy of the calling: The word walk marks the letter's practical half: believers walk worthy of their calling, no longer as the Gentiles do, but in love, as children of light and wisely. The new self shows in truth, honest work, kind speech and forgiveness (4:1, 17; 5:2, 8, 15).
Spiritual warfare: Christ has been raised far above every rule and authority, yet believers still face the schemes of the devil. They stand not in their own strength but in the Lord's, clothed in the armor of God and persevering in prayer (1:20-22; 6:10-18).

Main characters

Paul: The apostle and prisoner for Christ Jesus on behalf of the Gentiles (3:1), who calls himself less than the least of all the saints and yet received grace to preach the unsearchable riches of Christ (3:8). He asks for prayer to speak boldly as an ambassador in chains (6:19-20).
Tychicus: The beloved brother and faithful minister who carried the letter. Paul sent him to tell the readers how he was doing and to encourage their hearts (6:21-22), the same mission he received for the Colossians (Colossians 4:7-8).
The Gentile believers: The main readers, once called the uncircumcision and far off, without hope and without God in the world (2:11-13). Now they have been brought near by the blood of Christ and are fellow heirs with Israel (3:6).
The apostles and prophets: The foundation on which the household of God is built, with Christ Jesus as the cornerstone (2:20). To them the mystery of Christ has been revealed by the Spirit (3:5), and they head the list of gifts Christ gave to the church (4:11).
The Christian household: Wives and husbands, children and fathers, slaves and masters are addressed one by one. Each relationship is reshaped by reverence for Christ, the self-giving love of Christ and the knowledge that all serve the same Lord (5:21-6:9).
The devil and the spiritual powers: The ruler of the power of the air at work in the disobedient (2:2) and the rulers, authorities and cosmic powers of this present darkness (6:12). Christ is enthroned far above them (1:21), and believers resist the devil's schemes in God's armor (4:27; 6:11).

In-depth study of Ephesians

Introduction

Ephesians has been called the crown of Paul's letters. In six chapters it moves from eternity past, when God chose his people in Christ before the foundation of the world (Ephesians 1:4), to the everyday details of speech, work and family life. It begins with worship and prayer, and only then turns to instruction.

The letter answers two great questions: what has God done for us in Christ, and how should we live as a result? The first three chapters are full of indicatives, statements of what is true of believers. The last three are full of imperatives, beginning with the call to walk worthy of the calling they have received (4:1). Doctrine and life are never separated.

Who wrote Ephesians and when?

The claim of the letter

The letter opens with Paul's name (1:1) and twice calls him a prisoner (3:1; 4:1). The early church accepted it as Paul's without dispute; early in the second century Polycarp of Smyrna quotes Ephesians 4:26 as Scripture. Paul most likely wrote it during his house arrest in Rome, c. AD 60-62, and sent it with Tychicus together with Colossians and Philemon (6:21-22).

Modern debate

Since the nineteenth century some scholars have argued that a disciple of Paul wrote Ephesians after his death, perhaps around AD 80-90. They point to its long, liturgical sentences, words that do not appear in Paul's other letters, its focus on the universal church and its close resemblance to Colossians. Many scholars answer that Paul's style naturally changes in a meditative letter written for several churches, that he used secretaries, and that the resemblance to Colossians is best explained if the same author wrote both letters at the same time. The letter's own claims and the unanimous witness of the early church weigh heavily in favor of Paul.

A letter for several churches?

The words in Ephesus (1:1) are missing from some of the oldest manuscripts. The letter contains no personal greetings, although Paul had spent about three years in Ephesus (Acts 20:31), and Paul speaks as though some readers had only heard of his ministry (Ephesians 3:2). Many conclude that it was a circular letter for the churches of Asia, which would explain its general tone.

Literary style and structure

Worship that becomes teaching

Ephesians reads like a prayer turning into a sermon. The opening praise (1:3-14) is a single long sentence in the Greek, with the refrain to the praise of his glory marking the work of the Father, the Son and the Spirit (1:6, 12, 14). Two prayers frame the first half (1:15-23; 3:14-21), and a doxology closes it (3:20-21). Paul piles up words for God's abundance: riches, fullness, immeasurable power, love that surpasses knowledge.

Key words and images

The phrase in the heavenly places appears five times (1:3, 20; 2:6; 3:10; 6:12), more than anywhere else in the New Testament. The word walk organizes the practical section (4:1, 17; 5:2, 8, 15). Paul uses a rich set of images for the church: a body, a household, a temple, a bride, and a soldier in armor.

The flow of the letter

Greeting and praise for every spiritual blessing (1:1-14).
Prayer for knowledge and power (1:15-23).
From death to life by grace (2:1-10).
Jews and Gentiles made one in Christ (2:11-22).
The mystery revealed and a prayer for love (3:1-21).
Unity, gifts and the new self (4:1-32).
Love, light, wisdom and the Spirit-filled home (5:1-6:9).
The armor of God and closing (6:10-24).

Ephesians in the story of the Bible

Ephesians reads the Old Testament as a story that reaches its goal in Christ. Christ's exaltation fulfills the royal psalms: God seated him at his right hand, echoing Psalm 110:1, and put all things under his feet, as Psalm 8:6 says of humanity (Ephesians 1:20-22). Paul applies Isaiah 57:19, peace to those far and near, to Gentiles and Jews (2:17) and quotes Psalm 68:18 about the ascending conqueror who gives gifts (4:8). The temple, once the place where God dwelt among Israel, now has a new form: believers are being built together into a holy temple for God by the Spirit (2:21-22).

In the practical section Paul echoes Zechariah 8:16 on speaking truth (4:25) and Psalm 4:4 on anger without sin (4:26), cites the commandment to honor father and mother with its promise (6:2-3; Exodus 20:12) and grounds marriage in Genesis 2:24 (5:31). The armor of God is the armor of the Lord himself in Isaiah, who puts on righteousness as a breastplate and salvation as a helmet (Isaiah 59:17), and the feet ready with the gospel of peace recall the beautiful feet of the messenger of good news (Isaiah 52:7).

In the New Testament, Ephesians is a twin of Colossians, written at the same time, and adds to the story of Paul's ministry in Ephesus told in Acts 19-20. Later, Jesus' message to the church in Ephesus praises its endurance and its rejection of false apostles but rebukes it for abandoning the love it had at first (Revelation 2:1-7).

Ephesians and Jesus Christ

Christ is the center of God's plan. The Father's purpose, set forth in him, is to unite all things in heaven and on earth in Christ (1:9-10). God raised him from the dead, seated him at his right hand far above every rule and authority and every name, and gave him as head over all things to the church, which is his body (1:20-23).

Christ is also the one who brings peace. In him believers have redemption through his blood and the forgiveness of sins (1:7). He is our peace, who broke down the dividing wall and reconciled Jews and Gentiles to God in one body through the cross (2:14-16); through him both have access in one Spirit to the Father (2:18). He is the cornerstone of God's temple (2:20).

The risen Christ ascended far above the heavens and gives gifts to his people so that they grow up into him, who is the head (4:8-16). He loved the church and gave himself up for her, to make her holy and present her to himself in splendor (5:25-27). He is the model of love (5:2), the Lord whom believers serve in every relationship (6:7) and the source of the strength in which they stand (6:10).

Interpretive challenges

Chosen before the foundation of the world

Paul says that God chose believers in Christ before the foundation of the world and predestined them for adoption (1:4-5, 11). Some read this as God's choice of individuals for salvation; others stress that the choice is made in Christ and concerns the church as a people, which individuals join by faith. All agree that the passage is meant to produce praise and assurance, not speculation.

He descended to the lower regions

In 4:8-10 Paul quotes Psalm 68:18, where the psalm says the conqueror received gifts, and applies it to Christ, who gives gifts. Paul may be following an interpretive tradition known in his time, or drawing out the psalm's meaning, since the victor received gifts in order to share them. He adds that Christ first descended into the lower regions of the earth, which interpreters understand as his incarnation, his death and burial, or his descent to the realm of the dead.

Submission in marriage

The instructions to wives and husbands (5:22-33) follow a call to mutual submission (5:21). Some interpreters see in the passage a lasting pattern of the husband's loving headship and the wife's willing submission; others see a first-century household arrangement transformed from within by mutual submission. Both readings agree that Christ's self-giving love is the standard, and that the passage gives no license for domination or abuse.

Slaves and masters

Paul tells slaves to obey their masters as they would Christ and tells masters to stop threatening, because both have the same Master in heaven, who shows no partiality (6:5-9). He regulates an institution of his day rather than endorsing it, and his teaching on the equal dignity of all before the Lord undermined the very foundations of slavery.

Little-known facts

One long sentence. Ephesians 1:3-14 is a single sentence in the Greek, one of the longest in the New Testament; translations break it into several.
No greetings. Although Paul spent about three years in Ephesus, the letter names only one person besides Paul: Tychicus, its carrier (6:21).
Called Laodiceans. In the second century, the teacher Marcion knew this letter as the letter to the Laodiceans, and some have connected it with the letter from Laodicea mentioned in Colossians 4:16.
The dividing wall. In the Jerusalem temple a stone barrier kept Gentiles out of the inner courts, and two Greek inscriptions found by archaeologists warn foreigners that crossing it meant death. Paul was arrested after being accused of bringing Trophimus, an Ephesian Gentile, into the temple (Acts 21:28-29), so many think the dividing wall of 2:14 had a vivid meaning for him.
A city that lost its sea. Ephesus was a port city, but the river silt gradually filled its harbor, and its ruins now stand several miles inland.

How to study Ephesians

Read it in two halves

Read chapters 1-3 and ask what God has done; then read chapters 4-6 and ask how believers should respond. Notice the hinge word therefore in 4:1 and trace how each command grows out of the truths of the first half.

Pray the prayers

Paul's two prayers (1:15-23; 3:14-21) are models for intercession. Pray them for your class, family or small group, replacing the pronouns with names.

Teaching it in a class or small group

A six-week series works well, one chapter per week: blessed in Christ (1); saved and made one (2); the mystery and the love of Christ (3); unity and the new self (4); walking in love and light (5); home, work and spiritual warfare (6). Use the group to practice the letter itself: discuss how ethnic and cultural differences show up in your church, list practical ways to speak the truth in love, and end the series by reading the armor of God passage aloud and praying for one another (6:18).

Frequently asked questions about Ephesians

Who wrote the book of Ephesians?

The letter presents itself as written by Paul (Ephesians 1:1; 3:1), and the early church accepted it without question; early in the second century Polycarp of Smyrna already quoted Ephesians 4:26 as Scripture. Some modern scholars think a disciple wrote it after Paul's death, pointing to its style and its close ties with Colossians. Many others defend Paul's authorship, noting that style varies with purpose and secretary.

When and where was Ephesians written?

Paul wrote as a prisoner (3:1; 4:1; 6:20), most likely during his house arrest in Rome, c. AD 60-62 (Acts 28:30-31). Some suggest his earlier imprisonment in Caesarea (Acts 24:27) or an imprisonment in Ephesus. Tychicus carried it together with Colossians and Philemon, which were written at the same time (Ephesians 6:21-22; Colossians 4:7-9).

What is the main message of Ephesians?

God has blessed believers with every spiritual blessing in Christ, saved them by grace through faith and united Jews and Gentiles into one body, the church. Therefore they are called to walk worthy of that calling: preserving unity, growing to maturity, living holy lives, loving at home and standing firm against the devil (Ephesians 1:3; 2:8-10; 4:1-3; 6:10-11).

How many chapters does Ephesians have and how is it organized?

Ephesians has 6 chapters in two equal halves. Chapters 1-3 describe what God has done: spiritual blessings, salvation by grace and the union of Jews and Gentiles, framed by two prayers (1:15-23; 3:14-21). Chapters 4-6 describe how believers should live: unity and gifts, the new life, love and light, family and work, and the armor of God.

What is the armor of God?

In Ephesians 6:10-18 Paul pictures the believer as a soldier dressed in God's own armor: the belt of truth, the breastplate of righteousness, footwear ready with the gospel of peace, the shield of faith, the helmet of salvation and the sword of the Spirit, which is the word of God. The image draws on Isaiah, where the Lord himself wears righteousness and salvation (Isaiah 59:17), and it ends with a call to constant prayer.

Was Ephesians written only to the church in Ephesus?

Perhaps not. The words in Ephesus (1:1) are missing from some of the oldest manuscripts, the letter has no personal greetings although Paul spent about three years there, and Paul speaks as if some readers knew him only by report (1:15; 3:2). Many therefore think it was a circular letter for several churches of Asia, with Ephesus as its main destination.

What does Ephesians 2:8-9 mean?

It means that salvation is entirely God's gift: believers are saved by grace, through faith, and not by their own works, so no one can boast before God. Paul immediately adds that those saved are God's workmanship, created in Christ Jesus for good works (2:10). Good works are therefore the fruit of salvation, not its cause.

What does Ephesians teach about marriage?

Ephesians 5:21-33 sets marriage under the lordship of Christ, after a call for all believers to submit to one another out of reverence for him. Wives are to submit to their husbands as to the Lord, and husbands are to love their wives with the self-giving love Christ showed the church. Interpreters differ on how headship works in practice, but all agree that the model is Christ's sacrificial love.
