The document discusses when and how followers of Jesus were first called Christians. It describes how after Stephen's death, believers scattered from Jerusalem preaching the gospel not just to Jews but also Greeks in Antioch. Barnabas was sent to Antioch and saw evidence of God's grace, encouraging the believers. He found Saul and brought him to Antioch to teach believers for a year, and it was during this time that disciples in Antioch were first called Christians. The document also provides a definition of what it means to be a Christian according to the Bible.
