Mary birthed the flesh body, and she had absolutely NOTHING to do with the creation/formation of the Spirit, Emmanuel, means God with us, that was placed into her womb.
Now the fixation upon flesh and calling a fellow servant Queen of heaven does NOT come from the WORD, but of old early traditions where some goddess mated with this or that god and birthed little gods.
Excuse me if I say that “placed in the womb” sounds like insemination! Anyway the doctrine of the Immaculate conception is not expressed in physical terms at all. She was conceived naturally, but God created her soul with those virtues proper to the Mother of the Lord. But she owes all those virtues to her son whose divine nature exists before he enters her womb to assume also a human nature. We therefore speak of her as the Holy Virgin.
