Kids and step-kids fighting over the will.<quoted text>
Of course not. Luke/Acts is a work of fiction masquerading as history. It is based in part on some version of Mark, a polemic against the Twelve and their teaching. Luke, unlike Mark, wants apostolic authority. He relies on Mark but tones the rhetoric down. The closest followers of Jesus are no longer a threat -- or even alive. The first generation has passed, and the Jerusalem church as been long dispersed. Luke often is dated to the 80's, but outliers such as Burton Mack date it to the first quarter of the 2nd century. Regardless, it is time to take apostolic authority from its next of kin.
Guess who won?
(rhetorical, of course)
