Luke was the Author of “Acts” of all the Apostles. Luke was a companion of Paul in his traveling. Acts 16:10 After Paul had seen the vision. We got ready at ounce to leave for Macedonia, concluding that God had called us to preach the gospel to them. This is showing me that Luke was present with Paul at the events described in the “We” passages include the period of Paul’s two-year imprisonment at Rome. This was the time Paul wrote among other letters, Philemon and Colossians. In these letters he includes Luke among them. Through these letters for the Author of Acts, Luke is left as the most likely candidate.
