When you read this, you can perceive my insight into the mystery of Christ, which was not made known to the sons of men in other generations as it has now been revealed to his holy apostles and prophets by the Spirit. This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.
— Ephesians 3:4–6 —
In Ephesians 3, Paul explains how the unity of Jews and Gentiles in the church was a mystery hidden to the Old Testament people of God. In the strongest fashion he explains how Christ’s cross created “one new man” (2:15), tearing down the wall of hostility between Jew and Gentile. The result in Ephesians 3:6 is that Gentiles are “fellow heirs” (sugklēronomos) , “fellow members of the body”(sussōma), and “fellow sharers (summetoxa) of the promise in Christ Jesus”.
In these three desciptions, Paul uses the strongest terms to explain that the status of Jews and Gentiles is equal in Christ. No longer are the people of Israel advantaged over the Gentiles, as it was under the Sinai Covenant. Now in Christ Jews and Gentiles share equal statues. As Paul teaches, both are condemned for their sin and thus both redeemed by God’s free gift of grace—not by law-keeping. This makes all participants in Christ’s new covenant equals, brothers and sisters, co-heirs with their Lord.
Still, to get a handle on this newness in Christ, it is equally important to understand how the apostolic teaching was new—new to the first century believers and new to anyone today entering the church today. On that newness, Clinton Arnold gives a succinct outline of the ways in which the plan of God was previously unknown but now revealed through the gospel.
Under four points, he identifies (1) the means, (2) the Mosaic law, (3) the manner, and (4) the magnitude as constituting something different and greater than could be seen by the Old Testament saints. Here’s what Arnold writes (Ephesians, 190), Continue reading
