I was merely pointing out that:
1) Luke lists Jesus' lineage as through Joseph (that's the way lineages were presented). I didn't say Joseph was Jesus' "true" father, but, according to Levirate custom, is legitimately listed in His lineage (as listed in both Matthew and Luke), and,
2) Jesus has legal right to the throne through both Mary and Joseph (you might also want to read Jeremiah 22 and Haggai 2 for even more about the curse of Jeconiah - you see, it all has to fit together, not just selected peices).
Joseph was Jesus' earthly father, as accounted in Jewish law. That does diminish in the very least that Mary was "with child from the Holy Spirit". In fact, to me, it speaks of just how awesome God is - He made sure that there can be no legitimate argument that Jesus is not the Messiah.
Word omitted - good help is hard to find. Sorry.
