thecodont: <[>Same place Adam got his Y chromosome.
Actually, I agree. I believe all his flesh was from the same pure incorruptible flesh batch that God made Adam out of, and breathed the spirit of life into; and that He, Yehovah/Yehoshua/Iesous/Jesus donned it like a garment and was placed in Mary the host mother by the Holy Spirit, by the desire of The Father, agreed on before the foundation of earth and heavens. This negates any need for even the X chromosome from Mary.
Actually, Mary did get her X chromosome from Adam’s X chromosome, impure as it became because of Adam’s sin.
Paul was a good example of a legal Jew before The Temple according to the Laws of Moses. His mother was Jewish so in the eyes of the Temple Priest he was a Jew. Paul was also a Roman legally in the eyes of Rome because of his father being a Roman.
Jesus father is GOD as Mary was overshadowed by The Holy Spirit. Something I don't think at this time it is for us to fully understand but rather accept by faith. Thus the laws of Moses and the prophecies about Him were fulfilled with Mary being Jesus mother.
