Paul in the Book of Acts: Differences and Distance

The oldest and simplest explanation of first person plural language in Acts 16.10ff-that the author was a travelling companion of Paul-remains unconvincing to many scholars because of observed differences between what we see of Paul in Acts and in the apostle's letters. But in the light of more recent research on Paul, those differences (as offered in a contemporary critical NT Introduction) are not so significant as they were once thought to be.
