Paul and Barnabas returned to Antioch Syria after the Jerusalem council with a confirmation letter stating that Gentile Christians do not have to become Jewish in order to be saved by the Jewish Messiah Jesus Christ. They read the official letter to the church which was received with joy. Then Paul and Barnabas hotly contended with each other over follow up ministry in Galatia, which ended up in a temporary split between the two. They had served together through thick and thin times and would continue to serve the Lord in good times and bad. Paul went on to strengthen the churches in such a way that we still strengthens church today.
