Jesus cannot be the son of David because he was conceived by the Holy Spirit and not through Joseph, who is of the Davidic line.

The argument begins with the genealogy presented in the Gospel of Matthew, which clearly states that Jesus is the son of David. This genealogy traces Jesus' lineage through Joseph, highlighting the importance of legal descent in Jewish culture. Although Jesus was conceived by the Holy Spirit, Joseph's role as his earthly father establishes Jesus' rightful place in the Davidic line. Furthermore, the angel's address to Joseph as 'son of David' reinforces this connection, indicating that Jesus is recognized as part of this lineage through Joseph's adoption. Therefore, the claim that Jesus cannot be the son of David due to his miraculous conception overlooks the significance of legal lineage in the context of Jewish heritage.
