Luke's Acts of the Apostles is the only documentation available on the birth of Christianity, despite the author's vigorously disputed reliability as a historian. Daniel Marguerat avoids this true/false quagmire by establishing his evaluation of Luke's talent as an historian within the framework of ancient historiography (the rules of ancient historians and narrative criticism). His study portrays Luke as a skillful and sound theologian, and provides an original approach to the classic themes of Lucan theology.
