“Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;”
King James Version (KJV)
2:15 Having abolished by his suffering in the flesh the cause of enmity between the Jews and gentiles, even the law of ceremonial commandments, through his decrees - Which offer mercy to all; see #Col 2:14|. That he might form the two - Jew and gentile. Into one new man - one mystical body.
Eph 2:15 Having abolished in his flesh the enmity. While he was in the flesh the law condemned him and nailed him to the cross. In so doing it destroyed itself. The old covenant ended at the cross, when the new covenant was dedicated by the blood of Christ. Hence, the law, the wall between Jew and Gentile, "the enmity", was taken away. To make in himself of two one new man. Thus, the difference between Jew and Gentile being destroyed, both are made in the church one new race, "a royal priesthood, a chosen nation, a peculiar people" (1Pe 2:9), at peace among themselves.
