Ephesians: Uniting All Things in Christ, Part 2

The first half of Ephesians lays out God’s plan for the fullness of time, to unite all things in Christ, things in heaven and things on earth (Eph 1:10). Paul’s doctrine of unity can be summarized in the shape of a capital “I” (in a font with bars across top and bottom). The top horizontal bar represents the unity God has with himself, among the persons of the Trinity. The vertical bar represents the unity between God and his people, brought about by grace through faith. The bottom horizontal bar represents the unity among God’s people that ought to result.

Having followed Paul’s argument in Ephesians 1-3 in the previous post, let’s now walk through Paul’s application of the doctrine of unity within the life of the church.

Diversity Shouldn’t Divide the Church

Paul transitions to application with the urging to walk in a manner worthy of the calling described in the first three chapters (Eph 4:1). And what exactly is a manner of life worthy of the call to unity, in light of God’s plan to unite all things in Christ? It requires humble, gentle, and patient forbearance toward fellow church members (Eph 4:2). Such character arises only from an eager commitment to maintain the unity of the Spirit in the bond of peace (Eph 4:3).

Paul roots the unity of the church, explicitly, to the unity of the Trinity (Eph 4:4-6), which includes a victorious Christ ascending to take his throne while dishing out good gifts to his people. Psalm 68, quoted in Eph 4:8, likens the ascension of the ark of the covenant into Jerusalem to the arrival of God’s glory-cloud on Sinai. And Paul capitalizes on the image to explain how Jesus, the true ark, has entered heaven, the true sanctuary. This king cares enough about the unity of his body that he provides the church with leaders tasked with equipping members to serve one another—all so the community can grow together to maturity, according to the image of Jesus himself (Eph 4:9-14). That theological truth plays out in real life as people speak the truth to one another with love and build up one another in love (Eph 4:15-16).

In short, Eph 4:1-16 teaches that every church member is not required to be the same thing, do the same thing, or think the same thing. It assumes that there are differences among people, requiring patience and loving speech toward one another. In other words, diversity shouldn’t divide the church. But sadly, it often does, so the rest of the letter tells us what to do about that. We must give attention to four key areas, each marked with a renewed exhortation to walk (or, in the last case, to stand — Eph 4:17, 5:1, 5:15, 6:10-13).

Four Areas With Potential for Divisive Behaviors

The first area that requires attention in pursuit of unity is purity (Eph 4:17-32). However, notice that the chief problem of impurity is that it makes people like those who are alienated from—not unified with—God (Eph 4:18). The opposite of building up others in love is to serve oneself in sensuality and greed (Eph 4:19). This is not how you learned Christ! (Eph 4:20). A pure life according to the truth in Jesus requires each church member to do three things with their divisive behaviors:

Put off the old self, with its divisive and selfish desires (Eph 4:22).
Get a new way of thinking about how the calling to unity ought to drive your behavior (Eph 4:23).
Put on the new self, which is like God—fully unified with himself and with his body (Eph 4:24).

Paul gives four case studies to show practically how the three-step change process works. The first (Eph 4:25) is about overcoming the divisive power of lies: put off falsehood, start thinking about yourself and other Christians as fellow members of one another, and put on the speaking of truth. The second: Put off sinful anger, recognize it as an opportunity for the devil to rip relationships apart, and put on godly indignation (Eph 4:26-27). Theft (Eph 4:28) and rotten speech (Eph 4:29) round out the case studies, along with a concluding summary of the process (Eph 4:30-32).

Second, Paul highlights the role of love in the pursuit of unity (Eph 5:1-14). He introduced the topic in Eph 4:15-16, but he expands on it in Eph 5:1-14. Such love draws its power and motivation from the love of Christ for his people (Eph 5:1-2). The challenging work of love requires an extensive putting off (Eph 5:3-4), mind renewal (Eph 5:5-6), and putting on (Eph 5:7-14). The walk of love is a walk that will occupy us for the rest of our lives, and will take every bit of attention we can give to it. Since the Lord Jesus gave himself for us, it is worth it to give all we have to develop love in this walk with one another.

Third, Paul turns to the need for wisdom in the application of unity (Eph 5:15-6:9). Wisdom catalyzes unity by recognizing the times (Eph 5:16), knowing God’s will (Eph 5:17), and seeking the Spirit’s filling (Eph 5:18). The marks of those filled with God’s unifying Spirit include Scripture-filled speech (Eph 4:19a), song-filled thought-lives (Eph 4:19b), thanksgiving-filled attitudes toward everything (Eph 4:20), and reverence-filled submission within hierarchical relationships (Eph 4:21).

Submission is both complex and so easy to get wrong; frequently, we obey the wrong authorities, and we rebel against the right authorities. All such behaviors are divisive within the body of Christ, so Paul expands on this demonstration of Spirit-filling (submission) by exploring three pairs of hierarchical human relationships: wives and husbands (Eph 5:22-33), children and fathers (Eph 6:1-4), and slaves and masters (Eph 6:5-9). In each pair, Paul showcases the vertical unity between believers and God as both model and motivation for the horizontal unity among human relationships.

The fourth and final area that requires particular attention when pursuing unity in the church is that of spiritual warfare (Eph 6:10-20). As I’ve written elsewhere, we are in great danger of getting this text wrong when we read it in isolation from the argument Paul has been making all through the letter. True and lasting unity is one of the most difficult tasks facing the church of Jesus Christ. Look around, and it’s not difficult to find abundant examples of the evil one’s flaming darts (Eph 6:16) leveraging the opportunity granted him by our sinful anger toward one another (Eph 4:26-27), seeking to retain his dominion as the great power of the air (Eph 2:2). God called Paul to proclaim the astounding unity of people from all nations who believe, right in the face of the spiritual authorities in the heavenly places (Eph 3:8-10). Because they’re not pleased with this plan, they do all they can to break up that unity. Therefore, our fight for unity is never against one another within the church. It is always against those spiritual forces seeking to turn us against one another (Eph 6:12). And we cannot win unless we are strengthened by the Lord (Eph 6:10) by means of taking up his own armor (Eph 6:14-20).

Closing Greeting

Paul closes the letter with a reminder of his desire for unity with the letter’s recipients. This desire has led him to send Tychicus as his agent to share all the news and encourage their hearts. Finally, Paul wishes for peace in the church and grace toward all who love the Lord Jesus.

Conclusion

Because the unified God has united believers to himself, the church ought now walk worthy of its calling by pursuing a full-orbed unity. This unity does not require uniformity, but it presumes a diversity of opinions, personalities, social roles, and people groups. Because diversity naturally produces friction, the church ought to give particular attention to humble and patient purity, love, wisdom, and spiritual warfare in its pursuit of unity. This is the sort of walk worthy of the calling of the one God, who is Father, Son, and Spirit.
