Problem: Critics of the Bible argue that Luke made a historical error here. In Gamaliel’s speech, he mentions Theudas and Judas of Galilee. However, Josephus places Judas at about AD 6 (Antiquities of the Jews 18.4-10) and Theudas at about AD 44 (Antiquities of the Jews 20.97-98). How could Gamaliel (in ~33 AD) refer to someone who wouldn’t lead an uprising for at least another decade? And, why did he mention these men out of order?
Solution: Luke was not referring to the Theudas of AD 44. In his own chronology of the event, Luke places Judas after Theudas—who lived until AD 6 (“After this man…”). Instead, Luke was referring to an unknown man in the uprisings of 4 BC under the reign of Herod the Great. Barnett writes, “Theudas, however, was not an uncommon name and the period before A.D. 6 was very turbulent, especially after the death of Herod in 4 B.C. Indeed, had he placed Theudas after Judas, Luke would be really open to criticism, since Gamaliel’s speech occurred about ten years before the Theudas known to historians.”
Similarly, Howard Marshall argues that either (1) Josephus had his dates for Theudas wrong or (2) Luke is referring to a different Theudas. After all, Josephus refers to many different men with the same names: “Josephus describes four men bearing the name of Simon within forty years and three that of Judas within ten years, all of whom were instigators of rebellion.” Therefore, this theory is not hard to believe.
Critics formerly argued that Luke’s mention of “Lysanias the tetrarch of Abilene” (Lk. 3:1) was anachronistic, because King Lysanias reigned until 36 BC—not during Jesus’ time. However, Yamauchi writes, “Two Greek inscriptions from Abila, eighteen miles west, northwest of Damascus, have now proven that there was a ‘Lysanias the tetrach’ between the years A.D. 14-29.” Most of our problem with so-called historical errors in the Bible is not that we have too much information—but too little. As we learn more and more historically, the Bible is repeatedly confirmed.

“For before these days rose up Theudas, boasting himself to be somebody; to whom a number of men, about four hundred, joined themselves: who was slain; and all, as many as obeyed him, were scattered, and brought to nought. After this man rose up Judas of Galilee in the days of the taxing, and drew away much people after him: he also perished; and all, even as many as obeyed him, were dispersed. (Acts 5:36-37)”
