We've read a little about the church in Antioch before. It was one of the most important churches for the first several hundred years of Christianity and was a major center of learning. We've read before that Saul and Barnabas were there. Today we see them commissioned for a new evangelistic mission. We also see them in conflict with someone we see called a false prophet. We also see Saul getting his new name: Paul. Unlike many people in the Bible who get a new name, we don't learn anything about when or how Paul changed his name. Luke just announces it and from there on, he is Paul.
Blessings on your weekend,
