As God prepares the Church and does new things within it, he also prepares the people of that Church. In the case of Peter and Cornelius, he is bringing together the Jewish people of the promise and the Gentiles who are not of Abraham’s line. This was started on the day of Pentecost, when other languages were heard spoken, a sign that God was on the move outside of the established “in” crowd. Now God says it directly to Peter: I am making one Church, and it is all because of Jesus.
