They ignore...completely... For there is one God, and one mediator between God and men, the man Christ Jesus;<quoted text>
Saints are mediators Mary is a mediator.
In the way you explain Mary, why bother with the saints?
Try reason and logic -- no all-knowing Supreme being would possibly be swayed by a lesser spirit. If any mediator affected that Supreme Being's judgement, then that Supreme being is not.
Mary is barely mentioned in the Bible and was not mentioned once in the first Nicene Creed. But after the RCC became the official religion, Mary was needed to replace Isis and other female gods.
This mediator thing is now dated and absurd.
They have added the Priest, Mary and all the "Saints"....so they got lots of mediators!!!!!
