Skeptical Inconsistencies On The Historicity Of Christian Sources

"Harnack, Acts, 272: 'The agreement which in these numerous instances exists between the Acts (chaps. i.-xiv.) and the Pauline epistles, although the latter are only incidental writings belonging to the later years of the Apostle, is so extensive and so detailed as to exclude all wild hypotheses concerning those passages of the Acts that are without attestation in those epistles.' The logic is the same as arguments that a source unreliable where it can be checked should be assumed unreliable elsewhere (cf., e.g., Ehrman, Interrupted, 110, on Papias)." (Craig Keener, Acts: An Exegetical Commentary, Volume I [Grand Rapids, Michigan: Baker Academic, 2012], n. 120 on 238)
