Why Peter Went Among Gentiles

Acts 11:1-10

1  And the apostles and brethren that were in Judaea heard that the Gentiles had also received the word of God. 
2  And when Peter was come up to Jerusalem, they that were of the circumcision contended with him, 
3  Saying, Thou went in to men uncircumcised, and didst eat with them. 
4  But Peter rehearsed the matter from the beginning, and expounded it by order unto them, saying, 
5  I was in the city of Joppa praying: and in a trance I saw a vision, A certain vessel descend, as it had been a great sheet, let down from heaven by four corners; and it came even to me: 
6  Upon the which when I had fastened mine eyes, I considered, and saw four-footed beasts of the earth, and wild beasts, and creeping things, and fowls of the air. 
7  And I heard a voice saying unto me, Arise, Peter; slay and eat. 
8  But I said, Not so, Lord: for nothing common or unclean hath at any time entered into my mouth. 
9  But the voice answered me again from heaven, What God hath cleansed, that call not thou common. 
10  And this was done three times: and all were drawn up again into heaven.
