The Acts of the Apostles is a lengthy account of the development of the first generation Church. It is not in fact an account of the Acts of the Apostles in the broad sense. There are a number of significant differences in linguistic usage between Luke and Acts. These are listed in various works, classically perhaps by Hawkins in his Horae Synopticae in 1909. Some of the distinctive Lukan interests in women, tax-collectors and underdogs seem to be missing from Acts. Acts was written well after Luke and thus perhaps around 130 CE. By this time the author of Acts could well have known Josephus, and he very probably does. The most substantial argument that is produced against a late date for Acts is the observation that the author does not seem to know the Pauline letters.
