Reading the Acts of the Apostles is still essential to our knowledge of the beginnings of Christianity. The question is how credible Luke's historical account is from today's perspective. Daniel Marguerat's commentary wants to overcome the alternative between historical credibility and narrative fiction. To this end, he innovatively combines historical criticism and narrative analysis. On the one hand, he examines Luke's narrative art in order to grasp his interpretation of the events. The comparison with the Graeco-Roman historians makes it possible to recognize the rules of composition used. On the other hand, Marguerat looks for the possible traditions that Luke used. This methodological approach allows a new perspective on the work of Luke as the "first Christian historian". This commentary was originally written in French and is now available in German for the first time.
