Ephesians

Summary of the Book of Ephesians

Written: c. AD 60–62

Written during Paul's Roman imprisonment and likely intended to circulate among the churches of Asia Minor around Ephesus, this letter has almost no controversy to settle and no crisis to manage — which frees it to survey the gospel from the highest altitude of any Pauline letter. It opens with a single sprawling sentence of praise (1:3–14 in the Greek): chosen before the foundation of the world, redeemed through Christ's blood, sealed with the Holy Spirit, all "to the praise of his glory."

The first half is declaration. Sinners "dead in trespasses" have been made alive, raised, and seated with Christ in the heavenly places — "for by grace you have been saved through faith... not of works, that no one would boast." The long-hidden mystery is now public: in Christ, Gentiles are fellow heirs with Israel; the dividing wall of hostility is broken down and one new humanity created, a temple in which God dwells by the Spirit. Two recorded prayers frame these chapters, the second asking that readers grasp the breadth, length, height, and depth of the love of Christ that surpasses knowledge.

At 4:1 the letter pivots from what God has done to how the church walks: "walk worthily of the calling with which you were called." Unity and diverse gifts build the body toward maturity; the old self is put off and the new put on; believers walk in love, light, and wisdom. The household code reorders marriage, parenting, and work around Christ, with marriage itself presented as a picture of Christ and the church. The close is martial: the whole armor of God, prayer at all times, and a struggle that is "not against flesh and blood."

Written to display God's eternal plan to unite all things in Christ and to call the church to walk worthy of that calling.
