The purpose of the Virgin Birth story in regards to Jesus was to give him a miracle birth like all the other dying/saving  man/gods of the ancient world. Many of them were born of a human mother and a god for a father. Even Hercules had a human mother, Elcmene, and Zeus for a father. Dionysus had Semele for his human mother and, again, Zeus for his father, and the death of Dionysus was seen by his follers as dying for their sins.\n\nWhat everyone forgets is that IF Jesus was born of a virgin, then he cannot trace his lineage back to King David, and he therefore could not have been the Messiah! Some might say that this was to prevent him from being a descendant of Jehoikim, Jeconiah, or Shealtiel whose descendants, like Joseph, were cursed and would preclude a descendant of them from being the Messiah. But you cant have your cake and eat it too. He cant get the benefit from being a descendant of David through Joseph, without the curse that comes from being a descendant of those three, if he is to claim being from the House of David through Joseph.\n\nFurthermore, the Bible makes it clear that the Real Messiah is not adopted into the Davidic Line, but must be a direct bloodline descendant through his own human father back to King David, through Solomon.\n\nAnd if one were to actually pick up the Bible and read it, one would see that every single genealogy in the Bible traces the lineage through the father. If a mother is mentioned it is because she was famous, but the lineage still goes through her husband and not her. This is also true in the Christians' New Testament, where both Matthew and Luke trace Jesus's lineage through the males. This means that even if Mary was a descendant of King David, it would not matter because one's lineage is traced through one's father, not one's mother.
