The problem of Jew-Gentile unity wasn't unique to Galatia and Syria, but emerged everywhere that Gentiles were coming to faith in Israel's Messiah and entering God's covenant household - the household that had always been defined in terms of Abraham and the Hebrew people. For various reasons, the unity problem among the Roman believers was distinctive, if not unique, yet Paul addressed it in the same way as he did with the Galatian churches. The remedy for Jew-Gentile divisions among Christ's people - as indeed all expressions of Christian disunity - is rightly understanding and owning the truth of justification by faith in Him.
