That the Gentiles should be fellow heirs, and of the same body, and partakers of his promise in Christ by the gospel:
All Commentaries on Ephesians 3:6 Go To Ephesians 3
Jerome
AD 420
Now the meaning of fellow heirs is this: Just as there are many members in one body … and these, though in one body, have their differences and feel their own joy and grief in turn, so those who have believed in Christ, even if they have different gifts, are bonded together in the one body of Christ. .
