Dating acts between the evangelists and the apologists
Late daters of Acts agree with intermediate daters in questioning its historical value.But the chief significance of a late date for Acts takes us far beyond claims and denials of historical reliability.For example, Paul's letters reveal that he claimed to be an apostle and that this status was vital to him.But in Acts -22 the criteria for being an apostle definitively exclude Paul from membership in this group.In the first half of the second century, important Christian concepts were still in the process of being formulated.A major contributor to this proc-ess was Marcion of Sinope.
It an-swers the Marcionite contentions point by point.
It would be highly unlikely for an author who was also a companion of Paul to go to such lengths to exclude Paul from an office that he so vig-orously claimed for himself. First, Acts seems to be unknown before the last half of the second century.
Second, compelling arguments can be made that the author of Acts was acquainted with some materials written by Josephus, who completed his in 93-94 CE.
If the author of Acts knew of some pieces from this document, he could not have written his book before that date.
Third, recent studies have revised the judgment that the author of Acts was unaware of the Pauline letters.
