In Ephesians 2:11-22 Paul clearly teaches that Christ came to make peace between Jew and Gentile through the reconciling work of the cross. The Gospel of Christ is not only about reconciling us personally to God but also about reconciling us to each other in Christ! So much so that Paul can describe us as one new man, one body, fellow citizens, members of the same household, a holy temple joined and built together in the Lord with Christ Jesus himself being the cornerstone. In Paul’s view this is as much a part of the Gospel as God raising and saving us from our sins by his grace! In Paul’s view this is the mystery that has been revealed in the Gospel!
