Repschinski considers that there was not only a rift between Christianity and Judaism evidenced in the Gospels, but that there were substantial differences between the kind of Christianity Matthew and Paul would have promoted (Repschinski 2008, 50). There were certainly philosophical tensions between the Jewish traditions apparent in Matthew and the form of gentile Christianity which came to predominate (Repschinski 2008, 51).
Matthew's Gospel shows a clear concern that the Gospel should be made fully known to people of all nations (Repschinski 2008, 51-52). Counter to Sim, Repschinski takes many of the negative statements against gentiles in Matthew to show a contrast with Jesus' disciples (Repschinski 2008, 53). While even the gentiles get some things right, the disciples of Jesus do far better. Repschinski illustrates this using several passages from Matthew. While Matthew portrays Jesus' mission as focused to Jews, not Gentiles, there are still Gentiles around, participating in life and receiving blessing from God and His people (Repschinski 2008, 56).
In contrast to Matthew, Luke has normally been associated with a Gentile audience. However, Repschinski observes "Gentiles do not feature prominently in the Gospel at all" (Repschinski 2008, 57). In Luke's Gospel, while Jews are criticized, Gentiles are rarely characters who show up again and again (Repschinski 2008, 59). Even in Acts, when Paul is known for having a mission to Gentiles, he proceeds to go to the synagogue first, then to the Gentiles who receive him more favorably (Repschinski 2008, 60). In the Gospel, Luke tends to portray the Samaritans favorably. They are those, not accepted as fully Jewish, who turn to Jesus in faith and obedience (Repschinski 2008, 61). In Acts 8, the mission to the Samaritans is shown as fully developed. Repschinski also sees the mission to the Samaritans almost as a prototype for all New Testament mission to Gentiles (Repschinski 2008, 63). They are not previously bound to the Law and covenants. They are set apart from Jews.
Repschinski sees a growth of differences between Jewish and Gentile Christianity, as the implications of the background of the Mosaic Law or its absence are worked out. Both the Jewish and Gentile types of Christianity grow and flourish (Repschinski 2008, 64). The writings of Matthew and Luke show different emphases and approaches to bringing the Gospel to Gentiles. Yet they both deal with similar issues. Repschinski concludes, "We can only appreciate that for the early Christians, there was more than one way in dealing with the conflict between a rich tradition and a visionary future" (Repschinski 2008, 65).
