Elements of the Jewish faith tradition, including Torah observance and other Jewish practice, appear to be increasingly common among believers in Jesus. This development is troubling many Christians who, for doctrinal and practical reasons, believe it is heretical and brings division within the body of Christ (ecclesia). The objective of this research is to critically examine the biblical case against making a distinction between Jews and Gentiles within the ecclesia, considering the narrative of Acts 10:1–11:18, 15:1–28:31, and a key metaphor in Ephesians 2:14–16. Does the text validate or refute the notion that the ecclesia should make a distinction between its Jewish and its Gentile members? Three specific problems were addressed in five research papers for this compilation thesis, each employing methods of biblical exegesis and logical argumentation.
