…throughout the whole Church, October is the month dedicated to the Rosary.
The Rosary is my favorite prayer. A marvelous prayer! Marvelous in its simplicity and in its depth. In this prayer we repeat many times the words that the Virgin Mary heard from the Archangel, and from her kinswoman Elizabeth. The whole Church joins in these words. It can be said that the Rosary is, in a certain way, a prayer-commentary on the last chapter of the Constitution "Lumen Gentium" of Vatican II, a chapter which deals with the wonderful presence of the Mother of God in the mystery of Christ and the Church.
In fact, against the background of the words "Ave Maria" there pass before the eyes of the soul the main episodes in the life of Jesus Christ. They are composed altogether of the joyful, sorrowful and glorious mysteries, and they put us in living communion with Jesus through—we could say—his Mother's heart.
At the same time our heart can enclose in these decades of the Rosary all the facts that make up the life of the individual, the family, the nation, the Church and mankind. Personal matters and those of one's neighbor, and particularly of those who are closest to us, who are dearest to us. Thus the simple prayer of the Rosary beats the rhythm of human life.
