Since Christianity arises from Judaism, some traveling preachers from Jerusalem think that Jewish believers must remain true to Jewish rules regarding circumcision, Sabbath observance, and kosher food. If they rigorously follow the food rules, then Jewish believers are not supposed to share a meal with “unclean” Gentile outsiders, as Peter has been doing in Antioch. They advocate that Gentile outsiders need to follow Jewish ways and practices to become full members of the family of God. Paul—and the Jerusalem council (Acts 15)—strongly reject this. The apostle argues that it is only the faithfulness of Jesus and the presence of the Spirit that serve as the foundation of the new covenant and as the entrance into the people of God.
