The original Twelve Apostles had been selected by our Lord [Mark 3:13-19] from a group of many disciples and their commission was: [Matthew 10:5-6] These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not. But go rather to the lost sheep of the house of Israel.
When Peter received his vision it was difficult for him to comprehend as his ministry was directed to the circumcised [Galatians 2:7]. Paul had recently been converted but at this time was probably still in Arabia [Galatians 1:17] and therefore unavailable for this special mission to the Gentiles. No one probably would have believed him anyway [Acts 9:26].
So....enter Peter. Contrary to popular opinion the Apostles were not aware of the fact that Our Lord was going to include the Gentiles in his plan for salvation. It is quite evident when reading these scriptures that they were astonished at Peter's actions. [Acts 10:45] The circumcised believers who had come with Peter were astonished that the gift of the Holy Spirit had been poured out even on the Gentiles. [Acts 11:1-3] The apostles and the brothers throughout Judea heard that the Gentiles also had received the word of God. So when Peter went up to Jerusalem, the circumcised believers criticized him and said, "You went into the house of uncircumcised men and ate with them.
The early Church was thoroughly Jewish and these things that Peter was being asked to do [Acts 10:28] went against everything he had ever been taught. Peter was being asked basically to do an about face and even years later he still had problems accepting this [Galatians 2:11-13].
This is why Our Lord selected Paul....an educated, Jewish, Roman citizen. If any one could tackle this Gentile ministry, and be successful, Paul and his associates could. But....the ministry to the House of Israel and Judah still belonged to the twelve. [Matthew 15:24]
Luke 8
30 And Jesus asked him, saying, What is your name? And he said, Legion; because many demons had entered into him.
31 And they begged Him that He would not command them to go out into the abyss.
32 And there was there a herd of many pigs feeding on the mountain. And they begged Him that He would allow them to enter into them. And He allowed them.
33 And coming out of the man, the demons entered into the pigs. And the herd ran violently down a steep place into the lake and were choked.
Unclean spirit, unclean animal. 'nuff said. Would you like some fries with your demon sandwhich?
