The Birth of the Christian Church
The book of Acts begins with the phrase, “In my former book, Theophilus.” Acts is the second volume of Luke’s history of the Christian church. The gospel bearing his name is the “former book” mentioned in Acts 1:1. Luke was a physician, a traveling companion of Paul, a historian and a theologian. His two volumes, combined, make him the most prolific author in the New Testament. The gospel of Luke and the book of Acts were probably written during the two years that Paul was imprisoned in Rome.
