The author fails to consider the once Messiah and future Messiah aspect of Jesus Christ. His paternal and maternal lines were... what? The Second Coming is not for us, it's for the Jews. We were only grafted in because Jesus was rejected by the Jews.
He's to be forgiven, he's one of God's chosen people who have been blinded until the time of the end.
“His paternal and maternal lines were... what?”
Longer answer: there are two genealogies in the New Testament for Jesus. In Matthew, it is claimed that Joseph was a descendent of King Jeconiah, who in the Hebrew Bible was cursed to never have a descendent sitting on the throne of David and ruling any more in Judah (Jeremiah 22:30). Plus, if Jesus is actually descended from the human being Joseph, he would be a descendant of someone whom God said would never have a descendant sitting on the throne of Israel. In Luke, there is a different genealogy, which many Christian Scholars claim is through Mary. Putting aside for the moment the fact that under Jewish law one can inherit no status other than that of being Jewish from one’s mother, Mary herself is descended from Nathan, the brother of King Solomon, and not King Solomon himself. This would also disqualify him, again assuming that he could inherit some kind of status as a king through his mother, which is utterly forbidden under Jewish law.
Of course, there is also the argument that has been made buy some Christians that the genealogy simply did not matter, since he was the “son of God.”. Well, if the genealogy wasn’t important, why are there two separate genealogies for Jesus in two separate books in the New Testament? What would be the point? That is in addition to the problem caused by having a non-human parent (which sounds an awful lot like pagan theology to me): Jewish laws very specific that the Messiah will be a human being, descended from other human beings. There is no provision whatsoever in Jewish law or theology for the physical mixing of the Divine and human beings. God is God, and human beings are human beings. There is no combination of the two.
So what was it that you wanted to discuss regarding his genealogy?
