Well, Cognac, thanks. To reply to your question regarding Jesus' lineage and the fulfilled prophecies, I would argue that the "prophecies" are nothing more than the Gospel writers either deliberately falsifying facts about Jesus' life, embellishing, or misinterpreting such facts. I'm not one of those who believe the Gospels are entire fabrications, but I do believe the writers, whoever they were, desperately wanted to believe that this Jesus of Nazareth was the Jewish messiah, so they wrote the Gospels to that effect. I also hold to the belief that each Gospel was meant for the Greco-Roman world at large, but each had a particular segment of the Greco-Roman population in mind. The writers weren't idiots, and I don't think there was deliberate deceit; I think they meant well, but I think they also took great pains to portray Jesus as a divine figure, i.e. one who performed miracles, one who was resurrected from the dead, etc. Who in the Greco-Roman world would accept a Savior who wasn't divine? There were already plenty of divine or semi-divine figures in the Greco-Roman mythologies. Jesus had to stand out somehow.
As far as his lineage is concerned, I'm not familiar with what current scholarship says about that.
