What is the mystery revealed to the church?

• A. That Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel
• B. That Jews and Gentiles will be separated forever
• C. That the gospel is only for Jews
• D. That the church will be dissolved in the end times

Answer: (A)

The key idea being tested is the revelation of inclusion: the mystery is that Gentiles are brought into God’s people on equal terms with Jews. Paul describes this as Gentiles becoming fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel. This shows that through the gospel, the church is a single new humanity where both Jews and Gentiles share in God’s promises by faith in Christ.

That’s why the correct choice fits best: it states the inclusion and equal status of Gentiles within the body of Christ, which is precisely the revelation Paul emphasizes. The other options imply separation, restriction to Jews, or dissolution of the church, none of which align with this unveiling of a unified people of God.
