Who was given the gospel of the Gentiles and who was given the gospel of the Jews?
The gospel of the Gentiles, called the gospel of the uncircumcision, was committed to Paul. The gospel of the Jews, called the gospel of the circumcision, was committed to Peter. The Jerusalem leadership saw this as a fork in the road, two distinct directions after God had dealt with Jew only since Abraham.
Les explains that when the twelve and the Jerusalem leadership saw that the gospel of the uncircumcision had been committed to Paul, and the gospel of the circumcision to Peter, they realized there was a fork in the road. Uncircumcision means Gentiles, and circumcision means Jew. This body of truth was revealed to this apostle and was totally different from anything revealed before, a secret held in the mind of God. After coming down Jew only since Abraham in Genesis 12, God said in Acts chapter 9 that He was going to do something different.
But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
To whom were the gospel for the Gentiles and the gospel for the Jews committed?
Scripture states the gospel of the uncircumcision, meaning the Gentiles, was committed to Paul, while the gospel of the circumcision, meaning the Jews, was committed to Peter. Paul writes that God wrought effectually in Peter toward the circumcision and was mighty in Paul toward the Gentiles.
Was Paul's gospel to the Gentiles the same as Peter's gospel to the Jews?
No. The gospel Paul communicated among the Gentiles was not the same as what Peter and the eleven preached to the Jews. It was the gospel of the grace of God rather than the gospel of the kingdom, though both concern the same God.
