Well that was an enjoyable read, thank you.

I think to understand what is truly very confusing we need to consider a few principles. The Lord said "if you have known me you have seen my father". The children express the father. David has a spiritual, soulish and fleshly side. We can see this in his children. All the children involved in the rebellion were the fleshly expression. Solomon, the "wisest man on Earth" was the soulish expression. Finally, it is Nathan, who represents David's spiritual side. It is through Nathan that the prophecy to David is fulfilled (Mary is descended from Nathan). The soul is supposed to let the spirit take the lead, but as you have so clearly pointed out repeatedly Solomon usurps God's authority. As you have pointed out Solomon assumes that the prophecy will be fulfilled through him, but he is mistaken and his lineage is cut off from the promise. However, Joseph is descended from Solomon and so through marriage it is reunited with God's purpose.

Although there is nothing that will specifically tell you that Nathan the prophet is David's son, there is compelling evidence. First, the Bible tells us that all of David's other sons were caught up in rebellion, I would expect that would have disqualified all of them from the promise. Second, the first time we hear of Nathan the prophet he has direct access to the king (we don't know why). Read that story again and imagine it is a young son of David talking to his father. Third, we hear a lot about many of David's sons, if Nathan the prophet is not David's son then why don't we hear about his son Nathan who is a more important figure than Solomon (why would Jesus be descended through him rather than the other sons?)
