For several years, the gospel was limited to you had to be a Jew, a Samaritan, or a Jewish proselyte to become a Christian. It wasn't until Cornelius that God then opened the door to the uncircumcised Gentiles who were not Jewish proselytes that they could come in. So it went out to the Jews first. The Jews were privileged to get the gospel first and then to the Gentiles. But he didn't mean that in the church there's some kind of hierarchy between Jew and Gentile.
