No, I’m referring to your erroneous understanding.
You believe you understand with all your heart, but you really don’t.
God formed the baby Jesus inside Mary’s womb, without Mary’s DNA,

The Holy Spirit formed Jesus humanity entirely of Mary’s flesh, that is why he was truly man, the Son of Man and of the line of David the King who would Rule forever.
I do understand that makes Mary worship a little harder to get to.
