The leading argument against an early date for the Acts is drawn from the possible use by Luke of the writings of Josephus, and the crux of the question is in the words put into the mouth of Gamaliel (Acts v. 36, 37). The coincidence of the names of Theudas and Judas of Galilee (Acts v. 36, 37; Antiq. xx. v. 1 and 2) is striking and, if the two men named Theudas be identified and Josephus is correct, Luke is guilty of an anachronism in putting an allusion to him into the mouth of Gamaliel; for the Theudas of Josephus falls in the time of Fadus who was procurator under Claudius, about 45 A. D. The following points deserve to be noticed: (1) Luke had from Paul, whether or not Paul was present at the meeting of the Sanhedrin, the best means of knowing what Gamaliel, his teacher and the spokesman of the Pharisaic party, actually said. (2) The assumption that Luke was quoting Josephus is in itself very difficult when we compare the passages. Luke speaks of about four hundred under Theudas while Josephus mentions a great part of the people; Luke speaks of Judas while Josephus speaks of the sons of Judas. To quote thus loosely from his assumed authority and then to commit the further blunder of making Gamaliel allude to an event which occurred at least a dozen years later is, while possible, strangely out of keeping with Luke's proved care and accuracy in most of his historical allusions. The difficulty is acknowledged by those who make Luke dependent on Josephus. Why did Luke diverge from a correct narrative if he had one before him? Writers who affirm (Holtzmann) and those who deny (Schürer) the dependence on Josephus practically agree that if Luke had read Josephus he had forgotten him. (3) In the narrative of the death of Herod (Acts xii. 20 f.; Antiq. xix. viii. 2), where the two authors most obviously come together, both are plainly describing the same event, and yet seem to be quite independent both in the use of words and in the details of the description. (4) The cumulative evidence of an early date for Luke weighs heavily in the scale against the hypothesis of dependence upon the "Antiquities" written about 93 or 94 A. D.
