As Peter and all the other Apostles did, and as documented IN THE BIBLE (Peter with the VERY FIRST GENTILES, and Philip with the Ethiopian eunuch). The old hoo-ha about "only Paul ministered to the Gentiles" gets old after a while.
How then do you justify [Matthew 10:5-6] or [Galatians 2:11]????
Peter was not sent to evangelize Cornelius....he was sent by the Holy Spirit to show that Gentiles were also included in God's plan of salvation. Cornelius was already a man of God [Acts 10:2]. Paul....at the time....was sorting things out in Arabia [Galatians 1:17] or the task would have fallen to him. This is about 6 years after the resurrection and this concept (salvation for all) was not greeted warmly by some [Acts 11:1-2].
The Philip who did the evangelizing of the eunuch [Acts 8:26-29] was not the Apostle Philip.....who along with Peter had been directed to the circumcised [Matthew 10:5-6]....but the evangelist Philip [Acts 6:1-6]. Notice that this Philip goes to Samaria [Acts 8:5], cannot call up the Holy Spirit [Acts 8:16], and Peter and John have go to Samaria at the direction of the Jerusalem Church. This was in direct violation of Our Lord's command in [Matthew 10:5-6]. This caused the heresy and false doctrines of Simon Magus to enter the stage of history.
