There is another very good reason to believe that the genealogy in Luke is the genealogy of Mary. It has to do directly with the doctrine with the virgin birth, as well as some Old Testament prophecies. Genesis 3:15 speaks of "her seed" instead of "his seed." In any normal genealogy it always "his seed" that would be traced. Isaiah 7:14 mentions a virgin bringing forth a son. This was a sign to King Ahaz, a sign he did not understand, but a sign that would be fulfilled in the virgin birth of Christ. Isa.9:6,7 tells us that "a son is given."
Now in Jeremiah 22:24-30, we find a curse that is put on Jeconiah's house. Specifically:
28 Is this man Coniah a despised broken idol? is he a vessel wherein is no pleasure? wherefore are they cast out, he and his seed, and are cast into a land which they know not?
29 O earth, earth, earth, hear the word of the LORD.
30 Thus saith the LORD, Write ye this man childless, a man that shall not prosper in his days: for no man of his seed shall prosper, sitting upon the throne of David, and ruling any more in Judah.
No seed from Jeconiah could ever rule on the throne of David.
However, the Lord had promised to David in 2 Sam.7:16: "Thine house and thy kingdom shall be established forever before thee: thy throne shall be established forever."
But this promise could not be established through Jeconiah, that link had been forever cursed. It just so happens that Joseph, the legal father of Jesus was of this line. Their remained only one solution: Mary was a descendant of Nathan, another son of David (Luke 3:31). There is no other way that Jesus Christ could have escaped this curse except to be in the lineage of Mary. The fulfillment of Isaiah's prophecy of the virgin birth is the only way the Lord could be true to His promise to David and His curse on Jehoiachin. The only way that Christ could legally be the son of David is through Mary's genealogy. I would think it very important to include her genealogy. The Jews and early Christians were not ignorant of these things.
