Luke 1:1-4
1Inasmuch as many have undertaken to compile an account of the things accomplished among us,
2just as they were handed down to us by those who from the beginning were eyewitnesses and servants of the word,
3it seemed fitting for me as well, having investigated everything carefully from the beginning, to write
it out for you in consecutive order, most excellent Theophilus;
4so that you may know the exact truth about the things you have been taught.
Furthermore, I fail to see the connection between John
being the most "beloved" disciple and his Gospel's accuracy relative to the other three. Are you implying that his status
as Jesus' "favorite" meant that he had more incentive to write accurately or that he would've been privy to more aspects of Jesus' life?
