Acts 11:23-26

When he came and saw the grace of God, he was glad, and he exhorted them all to remain faithful to the Lord with steadfast purpose, for he was a good man, full of the Holy Spirit and of faith. And a great many people were added to the Lord. So Barnabas went to Tarsus to look for Saul, and when he had found him, he brought him to Antioch. For a whole year they met with the church and taught a great many people. And in Antioch the disciples were first called Christians.
