Oh, Dside, for heaven's sake, what kind of king was Jesus? Do you know something? You remind me of those followers of Jesus who were acclaiming him king of the Jews at the entrance of Jerusalem of all places. What did they really want, that Jesus be caught and crucified? No doubt about it. They got it. That's exactly what happened. And Pilate made sure they all saw the reason why Jesus was crucified; because they had acclaimed him king of the Jews in a Roman province, which was the Land of Israel at that time. The plaque was up there on Jesus' cross: INRI.
And now, about the issue of Mary's genealogy, even if you proved to me beyond the shadow of a doubt that she was from the Tribe of Judah, it would not at all help in the case of Jesus. According to Judaism, which was the Faith of Jesus, Tribal genealogy could never be passed down through the mother. Only through the father. Therefore, Jesus had to be a biological son of Joseph's.
