This is also a wonderful resource for Mary under her full title of “Co-Redemptrix & Mediatrix of All Graces.”

Lots of theology and discussion with scriptural cites.
This is very interesting:
“ORDINARY MAGISTERIUM ON MARY’S IMMEDIATE COOPERATION
IN THE OBJECTIVE REDEMPTION
by Fr. William Most”

I really enjoy Fr Most’s teachings and download the audio's off of Keep the faith .com
The people who knock Vatican 2 sometimes should realize that lots of good things came out of it regarding Our Blessed Mother.
As we see the attacks of on Our Lady unfold in modern times we can clearly see that the spirit was at work in the Church during Vatican 2 giving us answers to defend against the attacks on our Lady.
I recommend buying the book written by Cardinal Ratzinger(BenedictXVI) written in 1977 called Daughter of Zion,it's only 82 pages and is one of the best books on the Church's Marian beliefs I have ever read
I wish you a Blessed evening!
