Two into one
14 For He Himself is our peace, who has made both one and broken down the barrier of separation—the law with its commandments and ordinances— 15 having abolished the enmity through His ‘flesh’,"His ‘flesh’ " presumably refers to Jesus' physical body that went to the cross. Without the incarnation none of what Paul is discussing would have been possible. so as to mold the two [Jew and Gentile] into one new man in Himself (thus making peace), 16 and to reconcile them both in one body to God through the cross (by which He killed the enmity).In this paragraph Paul is dealing with the enmity between Jew and Gentile; within the Jewish ‘religion’ Gentiles were definitely second class citizens—to be saved a Gentile had to become a spiritual Jew. Within the Church of Jesus Christ that distinction is done away with; all are on the same footing, regardless of ethnic origin.
