They are the true ‘circumcision’ (Phil. 3:3; cf. Rom. 2:28–29; Eph. 2:11; Col. 2:11–13) and ‘the Israel of God’ (Gal. 6:16)… a broad spectrum of New Testament texts claim or assume that Gentiles as Gentiles are included in the group that they identify with the eschatologically restored Israel.
This passage argues that the New Testament’s most consequential theological move is the inclusive redefinition of Israel to encompass Gentile believers as full members of the eschatologically restored covenant people.
