Theudas (Theudas). Luke represents Gamaliel here about a.d. 35 as speaking of a man who led a revolt before that of Judas the Galilean in connection with the enrolment under Quirinius (Cyrenius) in a.d. 6. But Josephus (Ant. XX. 5, 1) tells of a Theudas who led a similar insurrection in the reign of Claudius about a.d. 44 or 45. Josephus (Ant. XVIII. 1, 6; XX. 5, 2; War ii. 8, 1 and 17, 8) also describes Judas the Galilean or Gaulonite and places him about a.d. 6. It is not certain that Josephus and Luke (Gamaliel) refer to the same Theudas as the name is an abbreviation of Theodosus, a common name. “Josephus gives an account of four men named Simon who followed each other within forty years, and of three named Judas within ten years, who were all instigators of rebellion” (Hackett). If the same Theudas is meant, then either Josephus or Luke (Gamaliel) has the wrong historical order. In that case one will credit Luke or Josephus according to his estimate of the two as reliable historians.
