Why is Paul's gospel to the Gentiles different from Peter's gospel to the Jews?
God committed the gospel of the uncircumcision—the Gentiles—to Paul, while the gospel of the circumcision—the Jews—was committed to Peter. Scripture presents these as two separate entities. The same God wrought effectually in Peter for the apostleship to the Jews and was mighty in Paul toward the Gentiles.
Les explains that God was now turning to the Gentile, while Israel would soon lose the Temple, the priesthood, the city, and the nation and be dispersed among all nations. The twelve were as yet unaware of this and thought they were still in control. Paul said those who seemed to be somewhat added nothing to him; they did not have near the revelations he had. Yet Paul had much to tell them they had never heard. When they saw that the gospel of the uncircumcision was committed to Paul, as the gospel of the circumcision was committed to Peter, they understood these were two separate entities. The same God who wrought effectually in Peter to the apostleship of the circumcision was mighty in Paul toward the Gentiles. Thus the distinction rests on God's separate commissions: Peter to the Jews, Paul to the Gentiles.
