If you take some time to read The Mystical City of God, which is Our Lady, you will read just how much Our Lord gave to Our Lady. In the 2nd volume, Our Lady visits her cousin Elizabeth. There is a servant lady there, who swears and curses. She has a demon and Our Lady asked Our Lord about her and Our Lord said that this was due to her sins, punishment. Our Lady has "sway" and had this servant lady released of the demon and her soul saved, if I recall. The Glories of Mary book says the same stories.
She is Co-Redemptorix. First volume of the City of God explains the Gifts given to Mary. Mary explains her "Portals" 12. She explains how man can be saved coming to her. She says there is no reason why one can not be saved for she has 12 portals to enter.
She has "sway". Makes me smile!
