This is a great video of the very profound writings of Venerable Mary of Agreda entitled: The Mystical City of God. It is one of our favorite books... a type of commentary on Holy Scripture and on the very key and profound role of Mary in the Church. It was one of Pope St. Pius X's favorite books, and Pope Pius XI said, it's such a great book that he recommended it to the entire Church, and gave his apostolic blessing to anyone who read it or spread devotion to it. It is the favorite book of many saints as well. Consider reading either the Abridged version or the 4 volume. CLICK TO SEE VIDEO
