"The agreement forged required mutual submission to the conscience of the other within the mixed-economy of the Jewish-Gentile church. Jewish Christians had to trust that the Gentiles were living according to the standards of the community in which they were inaugurated by baptism, and they had to forego their strict standards of absolute assurance regarding kosher purity. Gentiles, on the other hand, had to forego a freedom that was available in Christ, but was not conducive to united fellowship. Paul’s command that Spirit-filled members of a mixed-economy church would “submit to one another out of reverence for Christ” (Eph. 5:21) served as an ongoing reminder that ecclesial unity is not achieved without mutual sacrifice.
