Thanks, Peacefulpete. I appreciate your comments very much as well.
The stories in the New Testament are full of Jewish tropes, having been written by Jews, including Luke. So the stories of the 12 Apostles fits the idea of the Messiah establishing the Davidic monarchy due to the belief that during the Messianic Age the 12 tribes that were dispersed and lost would return and be restored to Israel--but now under Christ's leaders.--Matthew 19:28; Acts 1:6.
Whether or not there were a literal 12 Apostles is hard to say. The narratives in the gospels are hard to reconcile with historical reality. The authors were trying to teach religion like Gamaliel or Hillel, not write like Josephus. This is true even of Luke who composed the Acts of the Apostles.
Luke himself seems to be more of a Jewish convert than a "Gentile," as often claimed by the Watchtower. While it is clear that he was of Gentile birth, it is also clear he knows a lot about Jewish religion--a little too much for a mere Gentile. The first two chapters of his gospel are dripping with Judaism and details about the Temple, even what the inside of it looked like and liturgical details that most non-Jews today don't catch when reading it, such as prayer times during the day and how long preistly service lasted, etc. (Luke 1:8-11, 21, 23) And in Acts he talks about how Peter still keeps kosher and how all the Christians in Jerusalem are doing the same, following the Mosaic Law, even how Paul does this--though Paul keeps some of these details out of his own letters.--Acts 10:13, 14; 18:18; 21:20-26.
Luke, like the other authors, is obviously a Jew, though a convert, and when he writes narrative, it is likely filled with religious overtones, folklore, and the like. Luke 2:1-2 is definitely the employment of the genre of Jewish mythology. Not only do the dates not work for any of the rulers mentioned, nor the events, the Roman government never had a census at this time nor did it have a census where it would make people return to their own hometown to register. Could you imagine the chaos of having the population of the Roman Empire do this? It's a narrative device to set up the story of the "birth of Jesus" so he, a Nazarite, could be born in Bethlehem--an origin story genre similar to the types used in Genesis.
So the same author writing about the Apostles in Acts cannot be leaned upon for modern historical accuracy about what really happened in the first days of the Christian community.
