The phrase “one new man” comes from Ephesians 2:15 and describes the new spiritual creation that God has made in Christ. In the Church, the former division and hostility between Jew and Gentile has been abolished, and the two have been reconciled into one new entity. This “one new man” is not simply a mixing of the old categories while being a completely new creation in Christ that transcends ethnic and religious barriers.
The primary passage is Ephesians 2:11-22. Paul writes that Christ has broken down “the dividing wall of hostility” by abolishing the law of commandments expressed in ordinances, so that He might “create in himself one new man in place of the two, so making peace” (Ephesians 2:14-15).
This new man is further described as:
The “one new man” emphasizes that the Church is not an extension or continuation of Old Testament Israel, nor is it simply Gentile believers added to a Jewish foundation. It is something entirely new — a third entity created by the reconciling work of Christ on the cross.
In this new man:
This truth undergirds the unity of the Church and calls believers to live out the reconciliation that Christ has accomplished.
The creation of the one new man is the result of Christ’s reconciling work. Through the cross, He reconciled both Jew and Gentile to God in one body and put to death the hostility that existed between them (Ephesians 2:16).
This reconciliation has both vertical and horizontal dimensions:
The result is peace — peace with God and peace between former enemies. This peace is not merely the absence of conflict but the positive reality of unity in Christ.
The “one new man” is closely connected to the mystery of the Church. The mystery revealed to Paul includes the truth that Gentiles are fellow heirs and members of the same body (Ephesians 3:6). The creation of the one new man is the practical outworking of that mystery in the life of the Church.
While God’s covenants and promises to Israel remain, the Church as the one new man represents a new and distinct work of God in which ethnic and religious barriers are overcome in Christ.
The “one new man” reveals the depth of Christ’s reconciling work on the cross, which not only brings sinners to God but also brings former enemies together as one new spiritual humanity. This new creation forms the foundation for the Church’s unity and calls believers to live out the peace and oneness that Christ has already accomplished. It remains one of the most beautiful and practical expressions of the gospel’s power to transform relationships.
