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.

As the first historian of Christianity, Luke's reliability is vigorously disputed among scholars. The author of the Acts is often accused of being a biased, imprecise, and anti-Jewish historian who created a distorted portrait of Paul. Daniel Marguerat tries to avoid being caught in this true/false quagmire when examining Luke's interpretation of history. Instead he combines different tools - reflection upon historiography, the rules of ancient historians and narrative criticism - to analyse the Acts and gauge the historiographical aims of their author. Marguerat examines the construction of the narrative, the framing of the plot and the characterization, and places his evaluation firmly in the framework of ancient historiography, where history reflects tradition and not documentation. This is a fresh and original approach to the classic themes of Lucan theology: Christianity between Jerusalem and Rome, the image of God, the work of the Spirit, the unity of Luke and the Acts.
