The Paul's Social Network: Brothers and Sisters in Faith series focuses on the persons who constituted the Pauline network so that we may come to know them in ways befitting their first-century Mediterranean culture. In his book on Titus, Ken Stenstrup makes the distinction between these generations of writings and, by employing social-scientific methods, uses Titus to shed light on Paul as a change agent and leader. As one of Paul's coworkers, Titus provided stability and guidance to early Jesus groups. He was welcomed by these groups and reported their hospitality to Paul. Stenstrup emphasizes the collectivistic culture of the first century and explains how this influenced the relationships between Paul, Titus, and the early Jesus groups.
