Does Josephus prove a historical Jesus?

Does Josephus prove a historical Jesus?: The problems with this passage should be obvious to anyone with even a casual knowledge of Josephus.... He was thoroughly and ineluctably Jewish and certainly never converted to be a follower of Jesus. But this passage contains comments that only a Christian would make: that Jesus was more than a man, that he was the messiah, and that he arose from the dead in fulfillment of the scriptures. In the judgment of most scholars, there is simply no way Josephus the Jew would or could have written such things. So how did these comments get into his writings?
