Why Ephesians?
Ephesians is one of Paul's most theologically profound letters, presenting a cosmic vision of God's purpose to unite all things in Christ—a vision that begins with the reconciliation of Jew and Gentile into one new humanity and culminates in a renewed cosmos filled with God's presence.
This letter addresses a community living at the crossroads of cultures, religions, and spiritual forces. First-century Ephesus wasn't just another Roman city—it was a spiritual ecosystem where Greek philosophy, Roman imperial power, the Artemis cult, mystery religions, Jewish monotheism, and emerging Christianity all collided. Into this complex world, Paul announces that the crucified and risen Messiah has decisively defeated the powers, destroyed the walls dividing humanity, and is creating a new temple—not made of stones, but of people from every nation.
The Approach of This Commentary
This commentary approaches Ephesians through multiple integrated lenses, recognizing that ancient texts require us to understand both their original context and their enduring theological significance:
📜 Historical Context
Understanding first-century Ephesus—its spiritual ecosystem, the mystery religions that promised secret knowledge, the ethnic tensions between Jew and Gentile, the temple as central to ancient religious imagination, and the social structures Paul both affirms and subverts.
📖 Scriptural Imagination
Tracing how Paul draws on Israel's Scriptures—particularly the Torah, Isaiah, and the Psalms—to describe Christ and the church. Paul's imagination is saturated in the Exodus story, the prophetic vision of cosmic renewal, and royal psalms about God's anointed King.
🎨 Literary Design
Observing the letter's careful structure—how chapters 1–3 unveil the gospel story (what God has done) before chapters 4–6 describe the church's response (how we should live). Paul's rhetorical skill creates a literary architecture that mirrors the temple architecture he describes.
⛪ Theological Depth
Exploring Paul's mature theology—his understanding of election, the cosmic defeat of powers, the "mystery" revealed in Christ, the church as God's new temple, and the nature of spiritual warfare. These aren't abstract concepts but lived realities for believers navigating a complex spiritual landscape.
The Goal: Transformed Understanding
The goal isn't merely academic study but transformed vision—what Paul calls having "the eyes of your hearts enlightened" (1:18). We want to see reality as Paul saw it:
- Christ exalted above all powers—not as one option among many, but as Lord over every spiritual and structural force that claims authority
- The church as God's cosmic temple—not a religious institution, but the actual dwelling place where heaven and earth now meet
- Believers participating in Christ's victory—not passively waiting for salvation, but actively engaged in making God's wisdom known to the powers
- Unity across division—not as a nice ideal, but as the visible demonstration of Christ's triumph over the forces that divide humanity
📚 A Note on Method
This commentary integrates insights from multiple disciplines: biblical scholarship (commentaries, Greek analysis, background studies), the Bible Project's educational resources (particularly Tim Mackie's Ephesians classroom series), theological reflection, and practical application. Throughout, we prioritize understanding Paul's thought world before making contemporary applications. The goal is to let Paul's apocalyptic vision challenge and reshape our imaginations before we domesticate his message to fit our categories.
What Makes Ephesians Unique?
Several features distinguish Ephesians within the Pauline corpus:
1. Cosmic Scope
While other letters address specific congregational problems (Corinthians) or theological controversies (Galatians), Ephesians presents Paul's mature reflection on God's eternal purpose—spanning from before creation (1:4) to the consummation of all things (1:10). The canvas is vast: heaven and earth, past and future, powers and principalities, the mystery hidden for ages.
2. Temple Language
More than any other Pauline letter, Ephesians develops the church as temple theme. In a world where temples were the focal point of religious, economic, and social life—where the Jerusalem temple represented God's presence with Israel and pagan temples housed the gods—Paul announces that believers together are now God's dwelling place (2:19-22). This isn't metaphor in the weak sense; it's apocalyptic reality.
3. Mystery Terminology
Paul uses "mystery" (μυστήριον) six times in Ephesians—more frequently than in any other letter of comparable length. In a culture saturated with mystery religions promising secret knowledge to elite initiates, Paul hijacks the term: God's "mystery" is Christ himself, now publicly revealed to all who believe. There are no secret teachings, no graded initiations—only the shocking inclusion of Gentiles as full co-heirs with Jews.
4. Realized Eschatology
Ephesians emphasizes the "already" side of "already but not yet" more than Paul's other letters. Believers have already been raised and seated with Christ in the heavenly places (2:6). The new creation has already begun (2:10, 4:24). The temple is already being built (2:21-22). This doesn't eliminate future hope—Paul speaks of "the day of redemption" (4:30) and prays for ultimate fullness (3:19)—but the emphasis falls on participating now in Christ's cosmic victory.
5. Unity as Central Theme
The reconciliation of Jew and Gentile isn't one theme among many—it's the theme. The "mystery" revealed is that these two hostile groups are now "one new humanity" (2:15). The church exists to display this unity to the powers (3:10). Maintaining unity requires mature character (4:1-3) and is grounded in sevenfold theological realities (4:4-6). This unity isn't organizational but ontological—it's a new kind of human existence made possible by Christ's death and resurrection.
Who Should Read This Commentary?
This commentary is designed for:
- Pastors and teachers preparing to teach Ephesians in congregational settings
- Small group leaders wanting deeper background for facilitating discussions
- Seminary students studying Pauline theology and NT backgrounds
- Thoughtful believers who want to understand Scripture more deeply
- Anyone wrestling with questions about spiritual warfare, church unity, Christian ethics, or how the gospel relates to power structures
The commentary assumes basic biblical literacy but doesn't require knowledge of Greek or advanced theological training. Where technical terms appear, they're explained. The goal is accessibility without sacrificing depth—honoring both the complexity of Paul's thought and the need for clear communication.
How to Use This Commentary
The commentary is organized into major sections that follow Ephesians' flow:
- Introduction & Framework (this section) — Orientation to approach, authorship, and key background concepts
- Part 1: Historical Background — Deep dives into Ephesian context, Jew-Gentile tensions, cosmic powers, household structures, mystery religions, and temple theology
- Part 2: Chapters 1–2 — Paul's apocalypse: the blessing, prayer for revelation, from death to life, the destroyed wall, and the new temple
- Part 3: Chapter 3 — The mystery revealed, Paul's prayer for love, and the apocalyptic imagination
- Part 4: Chapters 4–6 — Unity and maturity, putting off the old humanity, household relationships, and spiritual warfare
Each section can stand alone, but they build on each other. The historical background sections illuminate why certain phrases would've been shocking to first-century ears. The exegetical sections work through Paul's argument carefully. The application sections help us see how Paul's vision reshapes contemporary discipleship.
Recommendation: Read the Historical Background sections first, even if you're eager to jump into chapter-by-chapter commentary. Understanding Ephesus's spiritual ecosystem, the Jew-Gentile divide, and temple theology will make Paul's arguments land with the force they originally carried.
📚 Key Sources for This Section
Paul doesn't write Ephesians in a vacuum. His imagination is soaked in Israel's Scriptures, especially the Torah, the Psalms, and the prophets like Isaiah. Those texts give him the categories to describe what God has done in the Messiah.
- Exodus and New Exodus – The story of liberation from Egypt, the Passover lamb, and God dwelling with his people shapes Paul's vision of rescue from sin and powers, and of God building a new dwelling-place in his people (Eph. 1–2).
- Isaiah's New Creation Hope – Isaiah's promises of a renewed world and a restored people under the reign of God echo in Paul's language about reconciliation, peace, and the "new humanity" created in the Messiah (Eph. 2:11–22; 4:24).
- Psalms and Royal Imagery – Royal psalms about God's anointed king inform Paul's language about Jesus' exaltation above all powers and his headship over the church (Eph. 1:20–23).
Ephesians is a re-telling of Israel's story around the crucified and risen Jesus, now extended to include the nations.
From Old Exodus to New Humanity
Against this backdrop of deep suspicion and hostility between Jews and Gentiles, Paul dares to claim that God has carried out a new kind of exodus. In the Messiah, God doesn't simply liberate one ethnic group from another; he liberates both from the deeper slavery of sin, death, and hostile spiritual powers, and then—astonishingly—brings them together into one body.
When Paul says that the Messiah "is our peace" and that he has made the two "one new humanity" (Eph. 2:14–16), he is reconfiguring Israel's exodus story around Jesus. The crucified and risen King leads a multi-ethnic people out of their old identities defined by hostility and into a shared identity defined by grace, forgiveness, and the Spirit's presence.

Ephesians is carefully designed. The letter falls into two major movements that mirror and depend on each other:
- Chapters 1–3: The Gospel Story – Paul unfolds God's eternal purpose to unite all things in the Messiah, drawing Jew and Gentile into one family. We move from cosmic blessing (1:3–14), to resurrection power and exaltation (1:15–23), to new life and identity (2:1–10), to the unveiling of the "mystery" of the multi-ethnic people of God (2:11–3:13), and finally to a climactic prayer for experiential knowledge of Christ's love (3:14–21).
- Chapters 4–6: The Church's Story – The "therefore" of 4:1 signals the pivot. In light of what God has done, the church is called to live out its new identity: guarding unity, growing in maturity, leaving behind old patterns, walking in love and light, reimagining household relationships, and standing firm against spiritual powers.
The historical background of Ephesus—its spiritual ecosystem, ethnic tensions, and power structures—forms the stage on which this two-part drama plays out.
📚 Key Sources for This Section
Ephesians presents itself as a letter from Paul, written while he was in prison (Eph. 3:1; 4:1; 6:20). Many who accept Pauline authorship date it to around 60–62 CE, during one of his later imprisonments (commonly identified as Rome).
Some early manuscripts omit the words "in Ephesus" in 1:1, and the letter's general tone has led many scholars to see it as a circular letter meant for a network of churches in Asia Minor, with Ephesus as a natural hub. On this view, the letter is addressed not to a single congregation but to a family of communities shaped by Paul's extended ministry in Ephesus.
However we resolve the details, Ephesians reflects Paul's mature reflection on the cosmic scope of the gospel and the identity of the church as God's multi-ethnic new humanity.
How Ancient Letters Worked
In the first-century Mediterranean world, letters like Ephesians were collaborative projects. A trained secretary (an amanuensis) would often shape the physical wording and layout as the author dictated the message. Trusted co-workers then carried the letter, read it aloud in the gathered community, and clarified its meaning.
If Ephesians functioned as a circular letter, it likely arrived in a city like Ephesus first, then traveled outward along relational and trade networks to other assemblies. That fits the letter's broad tone and its sweeping vision of Jew and Gentile united in the Messiah.
