All these are your opinion, and it contradicts scripture. For example, when a woman is described in the scripture as the mother of Christ, I do not fantasize what it means, I read what is written.
Of course, John 14:6 is the Catholic teaching, as is the entire Holy Scripture.
These are also the beliefs of men more knowledgeable than me. And what contradiction of scripture? Name one thing I stated that contradicted scripture. I can use scripture to verify everything I said.
Mary was a sinner the same as me. She is not devine. And has no power to forgive sins or provide salvation.
Her blessing was that God found favor with her to bear the savior of the world.
