how can we live out this unity in diverse communities without erasing distinct identities?

Adds the setting and its conversation across both testaments.

Ephesians 2:14-16

“For he is our peace, who made both one, and broke down the middle wall of partition, having abolished in his flesh the hostility, the law of commandments contained in ordinances, that he might create in himself one new man of the two, so making peace, and might reconcile them both in one body to God through the cross, having killed the hostility thereby.”

The Apostle Paul, writing from prison, is addressing Christians in Ephesus, a bustling Roman city with a mix of Jewish and non-Jewish believers. He's reminding them that their faith in Jesus has brought together people who were once deeply divided, forming a single new community.

How might genuine unity be nurtured in communities where historical divisions run deep, without demanding assimilation or ignoring the richness of different backgrounds?

Then — the setting

This letter was likely written by Paul in the 60s CE, during one of his imprisonments (possibly Rome), to the Christian community in Ephesus, a major city in the Roman province of Asia (modern-day Turkey). The 'middle wall of partition' most immediately referenced the physical barrier in the Jerusalem Temple that separated the Court of the Gentiles from areas only Jews could enter. More broadly, it symbolized the vast cultural, religious, and legal distinctions that separated Jews and Gentiles for centuries. For Jewish people, the Law (Torah) defined their identity and marked them as distinct, while Gentiles were often considered 'unclean' or outside God's covenant. This passage addresses the radical theological and social claim that Jesus, through his death, has overcome this fundamental division, creating a new, unified identity.

Across the Testaments

The Old Testament established a covenant relationship primarily with the nation of Israel, setting them apart from other nations through laws, rituals, and a distinct identity (e.g., Exodus 19:5-6). While prophets sometimes envisioned a future where Gentiles would come to worship Israel's God (e.g., Isaiah 2:2-4), the primary emphasis was on Israel's unique role. Ephesians 2:14-16 takes this further by declaring that in Christ, the dividing wall between Jew and Gentile has been *broken down*, and they are not merely worshiping alongside each other, but have become 'one new man.' This New Testament perspective doesn't erase Israel's past or promises but redefines the basis of inclusion and unity, extending God's covenant people to include all who believe, regardless of their prior ethnic or religious background, without requiring Gentiles to become Jews first (as seen in Acts 15).
