If you deny Christ having a human Mother you end up denying Christ as Incarnate God in the flesh -The second person of the Holy Trinity .
You're walking along the same heresy as Nestorius by taking out the human connection of Mother in the Virgin Birth you end up denying the Trinity of God the Son being fully Man
Perhaps you need to take some time off of FR and really study Christian history and contemplate some things
The Second person of the Trinity didn’t come into existence when Mary conceived.
Christ, as part of the Trinity, existed without beginning as the Father and the Holy Spirit. He appears at several times in the OT in a theophany.
She gave birth to the physical body He lived in on this earth. She did not give birth to His spiritual nature.
