Ephesians 2:16 Commentary: The Cross That Kills Hostility

Paul writes to a congregation that includes both Jewish and Gentile believers. The “middle wall of partition” (Eph 2:14) echoes the physical barrier in the Jerusalem temple that separated the Court of the Gentiles from the inner courts reserved for Jews, a constant reminder of the division the law created between the two groups. That law, “contained in ordinances” (v. 15), refers primarily to the ceremonial regulations that marked Israel as God’s distinct people and excluded Gentiles from full participation in the covenant community.

In first-century Ephesus, this division was more than religious. Jews and Gentiles lived with mutual suspicion, shaped by centuries of history: Jewish exile and Gentile oppression, cultural contempt on both sides, and the daily friction of food laws, purity rules, and social boundaries. Paul’s readers knew this tension personally. By the cross, Christ does not merely lower the wall, he abolishes the ordinances that gave it force. The “enmity” that is slain is therefore immediately the hostility between Jews and Gentiles, as Matthew Henry and others note. But beneath that lies a deeper hostility. The same law that separated Jew from Gentile also condemned all people as sinners before God (Rom 8:7). The ceremonial law, as Gill explains, could not remove sin; it only pointed to the need for a perfect sacrifice. When Christ died, he satisfied the law’s demands and removed the barrier between humanity and God.

This double reconciliation means the cross addresses the root of disunity. The Gnostic and Jewish mystical speculations that some scholars detect in the background of Colossians were absent for Paul: the only mediator is Christ crucified, and the only peace is the one he accomplished through his body. The temple barrier is gone; the enmity of a fallen heart is gone; what remains is a new humanity, one body, brought near to God and to each other.

The supplied sources note no significant textual variants in Ephesians 2:16. The only marginal difference appears in the phrase “thereby” (Greek en autō, lit. “in it” or “by it”), which the KJV margin marks as “in himself.” This variant (reading en autō as reflexive) does not affect the meaning: the cross is either the instrument or the location where the enmity is slain. The text is well-established across manuscript traditions.

From the early centuries, Ephesians 2:16 was read as the charter of church unity. Irenaeus and later patristic writers saw in it the fulfillment of God’s plan to gather Jews and Gentiles into one body through the cross. During the Reformation, emphasis shifted to the vertical dimension: Luther and Calvin stressed that the enmity abolished is primarily the condemnation of the law against sinners, so reconciliation with God is the foundation. In the modern ecumenical movement, this verse became a key text for bridging confessional divisions: the cross kills the hostility between Catholic and Protestant, Jew and Gentile, slave and free. Hymns such as “There Is a Balm in Gilead” echo the imagery of the cross healing the deep rift in humanity. Throughout these eras, the central conviction has remained: Christ’s death is the decisive act that makes peace between divided peoples and between a rebellious world and its Creator.

Three-point outline

1. The target of reconciliation: “Both” (Jews and Gentiles) are reconciled to God. The cross addresses two parties and a common destination.
2. The means of reconciliation: “Through the cross.” Christ’s death is the propitiatory sacrifice (Calvin) that satisfies God’s justice and removes the cause of enmity.
3. The result of reconciliation: Hostility is slain. The cross kills the enmity, both the horizontal division between groups and the vertical division between sinners and God, creating one body united in peace.

Five-point outline

1. The two parties separated by a wall: Jews and Gentiles are defined by the law that kept them apart (v. 14, 15).
2. The single sacrifice that tears it down: Christ’s cross “slays” the enmity (the verb apokteinō means to kill, to put to death). The enemy is not people but the hostility itself.
3. The one body where unity is embodied: “In one body” likely refers both to Christ’s physical body (the locus of sacrifice) and to the church, which becomes the new humanity.
4. The divine destination: Reconciliation is “to God.” Horizontal peace without vertical peace is incomplete; the cross secures both.
5. The ongoing proclamation: Christ “came and preached peace” to those far off and near (v. 17). The accomplished work continues to be announced.

Illustration hooks

• A family feud between two siblings that seems impossible to resolve until they realize that both are equally estranged from their father and that the father himself steps in, at great cost, to bring everyone together. The deep problem is not just sibling rivalry but mutual alienation from the parent.
• Two neighboring countries separated by a concrete wall. One day the wall is demolished. But the citizens remain wary until they face a common threat from a third aggressor and unite in defense. The cross demolishes the wall and then, in facing the deeper enemy of sin and death, creates genuine solidarity.
• A marriage where each spouse blames the other for the coldness. A counselor shows them that the root issue is their individual distance from God; when each is reconciled to God, the mutual hostility naturally dissolves, not because they tried harder, but because the cause was removed.

Questions your congregation is asking

• Does the cross only fix the problem between me and God, or does it also fix the divisions I have with other people?
• How can I be reconciled to someone whose beliefs or background deeply divide us when the division seems cultural, not just spiritual?
• If the hostility is already slain, why do we still experience conflict in churches?

This verse connects two kinds of reconciliation: the one between Jews and Gentiles (horizontal) and the one between all sinners and God (vertical). Paul insists that the cross addresses both. The group can think about how these two dimensions relate, whether healing one depends on the other, and what that means for their own relationships.

Discussion questions

1. Read Ephesians 2:11, 18 as a whole. What does Paul tell the Gentiles to “remember” (v. 11)? Why does he start there?
2. What is the “middle wall of partition” (v. 14) and how does the cross remove it?
3. Our verse says the enmity is “slain” or “killed” (apokteinō). Why does Paul use a violent word instead of something softer like “cancelled” or “removed”?
4. The enmity seems to refer both to hostility between groups and hostility between people and God. How are these two kinds of enmity connected in your experience?
5. Why does Paul specify that reconciliation happens “in one body”? What does that imply about the church’s identity and mission?
6. If the hostility is already slain, why do Christians still experience division? Does the verse describe something that is already fully true, or something that is still being worked out?
7. Think of a relationship in your life that feels hostile. What would it mean to let the cross “kill” that hostility rather than trying to manage or ignore it?
