how might this 'one new humanity' inform our approach to modern social divisions?

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 encouraging Gentile Christians in Ephesus, a city known for its diverse population and various religious practices. He reminds them of their past alienation from God and from Israel, and then explains how Jesus has brought both groups together into a single new community.

What specific 'walls' in our current society might this passage call us to confront or dismantle?

Then — the setting

Paul likely wrote Ephesians around 60-62 CE, while imprisoned in Rome, to Christians in the Roman province of Asia, particularly addressing the church in Ephesus. The 'middle wall of partition' (μεσότοιχο τοῦ φραγμοῦ) likely refers to the literal wall in the Jerusalem Temple that separated the Court of the Gentiles from the inner courts accessible only to Jews, symbolic of the broader social, cultural, and religious divide between Jews and Gentiles. The 'law of commandments contained in ordinances' (τὸν νόμον τῶν ἐντολῶν ἐν δόγμασιν) refers to aspects of the Mosaic Law, particularly its ceremonial and distinct ethnic markers, which created separation. Paul’s audience would have been acutely aware of these distinctions, as Gentiles were considered 'far off' from the covenants and promises given to Israel.

Across the Testaments

This passage is in the New Testament and speaks to the revolutionary inclusion of Gentiles into God's people, a concept anticipated in the Old Testament but radically reconfigured by Jesus. While the Old Testament often emphasizes Israel's distinctiveness and covenant relationship with God (e.g., Exodus 19:5-6), it also contains prophecies of God's blessing extending to all nations (e.g., Isaiah 2:2-4, Zechariah 8:20-23). Paul's argument is that through Christ, the Gentile inclusion isn't merely an addition, but a breaking down of previous barriers, creating a genuinely 'new man' (or humanity), where Jew and Gentile are reconciled and united in a way not possible under the old covenant.
