Can the Bible interpret itself? Is the Bible the sole source for determining Church doctrine, or do we need traditions and Church teaching as well? What does the Bible say?

www.amazon.com The author of the Catholic book quoted, Liguori, is not only a Catholic saint but was raised to doctor of the church. That is very important in Catholicism. In the first few pages of “The Glories of Mary” there is a stamp of approval saying the book was reviewed and approved of by John the Archbishop of New York in 1859. So yes Rome does support it. Millions of laymen Catholics affirm these teachings. The Roman religion never condemned these views or this book and many believe the themes, (Mary being mediatrix, mother of humanity, co-redeemer etc) will probably be made dogma soon. Roman apologists defend this book and its views. Hence, this is modern Catholic teaching. Here is some material showing Pope John Paul II affirming that Mary is co-redeemer and prominent Cardinals pushing for Mary to be dogmatized as how the book in this video portrays her – Mother of humanity, Co-redemptrix, Mediatrix, and Advocate for the human race: www.ewtn.com Hence, this video does represent current Catholic teaching.
