what current social or cultural 'walls' are most resistant to this kind of reconciliation?

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 is writing to a mixed community of Jewish and Gentile believers in Ephesus, likely in the mid-first century CE. He's emphasizing how their shared faith in Jesus has brought together groups previously separated by deep cultural, religious, and social divisions.

What steps can individuals and communities take to actively dismantle modern 'walls' that create hostility and prevent reconciliation?

Then — the setting

Paul wrote Ephesians to a mixed audience of Jewish and Gentile Christians in the Roman province of Asia Minor around 60-62 CE, likely from prison in Rome. The 'middle wall of partition' metaphor likely refers to the physical barrier in the Jerusalem Temple that separated the Court of the Gentiles from the inner courts accessible only to Jews, symbolizing the deeply entrenched religious and social boundaries between Jews and non-Jews. The 'law of commandments contained in ordinances' refers to aspects of the Mosaic Law that defined Jewish identity and separated them from Gentiles, such as dietary laws, circumcision, and Sabbath observance. For Gentiles to join Israel, they typically had to convert fully to Judaism.

Across the Testaments

This passage builds upon Old Testament prophecies that envisioned a future where Gentiles would be included in God's people (e.g., Isaiah 2:2-4, Zechariah 8:20-23), but it radically redefines the terms of that inclusion. In the Old Testament, Gentiles often came to Jerusalem to worship or were grafted into Israel's existing structure. Here, the New Testament proclaims that Jesus himself has 'created one new man' (a new humanity) out of both, actively abolishing the dividing law and reconciling them directly to God through his death, rather than requiring Gentile assimilation to Jewish legal identity. It's a new, unified body in Christ, not merely an expansion of the old.
