And therein is the problem with roman catholicism. Everything has to circle through Mary.
Mary does not play a role in our salvation.
Mary is the mother of Christ. That is all.
She is not a mediatrix, co-redemtrix or advocate.
That roman catholicism advances this is a false teaching.
I am not the one to give you a tutorial on Mary. I was once like you, for many decades. I know a brick wall when I see one. I was one. It would be a waste of my time and yours.
Faith is a gift, and understanding a fruit of the Spirit, but the Church with Vatican II has itself rather shut out Mary as the hierarchy entertained infiltrators and heretics who were/are enemies of the Church.
I would not expect you to even stumble across any understanding on Mary. Many Catholics by now do not know her either, as the centuries of the faithful did, who came before them.
It is admittedly a great loss for all. The wolves have struck, to steal and destroy and buried plenty of knowledge.
