Not quite. The egg provides 1/2 of the genetics. Was Jesus, then, genetically related to Mary’s family or was he totally God and totally man?
In order for Jesus’ personhood to be totally divine he could not have human genetics. IOW the HS did not impregnate Mary’s egg but Jesus was implanted in her womb in whole. Get it?
Jesus was a true descendant of Mary. Otherwise, since he had no human father, he is not a member of the human race. Only a true son of Adam could stand in as a substitutionary sacrifice for other men. Only a man could intercede for other men as a priest. And, finally, if Christ has no human ancestry, then he cannot be a son of David and has no just claim to be "king of the Jews," and he lied.
Theology matters. And sometimes, even the seemingly fiddly little details have huge implications.
