God authored Acts by way of the unique perspective and divine gifting of the author known as Luke. Luke was both a historian and theologian. He arranged his historical material according to its divinely inspired theological purpose. In the book of Acts, Luke documents the development of the early church and provides a historical account of Peter and Paul’s ministries. Luke establishes the apostolic authority of Paul in the book of Acts by developing a strong literary connection between Peter and Paul, therefore presenting them as equals. This literary connection makes it clear that the apostolic authority of Paul cannot be discredited without first discrediting Peter’s established apostolic authority. Peter’s apostolic authority cannot be discredited however, since Jesus Christ is acknowledged as having established Peter’s apostolic authority in Matthew 16:17-20. These two very different men devoted their lives to proclaiming the same gospel message, both to the Jews and the Gentiles.
