A woamn who carries a child to term is that child's mother. There is nothing in it that says she must have given that child its life. You would make Christ into a demigod, "conceived" by some strange junction of Mary's halpoid DNA and some God's "genes."
Christ had no physical relationship to Mary?
Is that what you are saying?
In what way then is Christ the Son of Man?
In what way is Christ the Son of David?
In what way is Christ the seed of Abraham?
