Mary's heart was fresh and pure, uncontaminated by sin, uncorrupted by the wicked touch of a polluting world. Eve's soul had been sullied by the malevolence of Satan. Some 4000 years rolled on, and still the tide of sin continues to engulf the children of Adam. But Mary was an exception. Mary came into this world, beautiful with a halo of heaven-born grace.

Mary's countenance, her eyes, her conversation, her manner, her whole being would radiate an atmosphere of peace. They would exhale a divine something that would inspire respect and veneration. With St. Paul (Gal. 2-20), Mary could say: "I live; now not I but Christ lives in me." And she could  pronounce those other words: "We are transformed into the same image, from brightness unto brightness as led by the Spirit of God."

Yes, Mary's soul went from brightness to brightness. A white object can grow dazzling white. Now, Mary's soul became whiter and whiter. It grew dazzlingly white. And Mary's thoughts were ever intent upon God and the things of God.

In ordinary life, we meet people whose only thought is of money. They are always speaking of it; always wondering how they can increase their wealth. But Mary would always be thinking of grace and to increase. She could say with truth: "I always do the things that please Him."

What an object lesson to us is Mary's purity of soul! We are here on earth to grow in holiness. To make people holy, Christ instituted the Sacraments. Catholic schools and Catholic Churches are built to make people holy. Catholic young men are ordained and consecrated to the service of God to make people holy. To grow in holiness and to spread its growth in others, the hermits made the caves of the desert resounding with sighs of repentance and with hymns of praise.

Mary, Undefiled, has intense compassion on those whose souls are covered with the leprosy of sin, for Mary knows the fearful nature of sin. She realizes that the angels were hurled down from heaven on account of sin, and that Hell was created to punish sin; that her Divine Son died a horrible, bleeding and mangled death to atone for sin.

What comfort is the thought of Mary's motherly love to those who are living a life of sin!  Many are submitting to the yoke of lust, greed, abortion, homosexuality, living together not married, and many do nothing about the evil which surrounds them. They are so entangled in sin that any thought of breaking away seems almost an impossibility.

Let us beg Mary's intercession that we may grow to be, like unto her. Let us follow her example. Let us give ourselves to her to be molded after her pattern. If we are faithful to Mary, what a welcome will be ours in her Son's royal household! What a reward is awaiting us, a reward which the most Merciful of Masters will give to us! Moreover, we shall he His companions, His friends, His brothers for evermore.

From 1962 - 1965, the Catholic Bishops from all over the world gathered at the Vatican in Rome. For four years the bishops met under the authority of the Pope. Their meeting was called "Vatican Council II". That Council gave the Church sixteen documents. One of those documents was on the nature of the Church. The last chapter by the world's bishops on the nature of the Church was on Mary, the Mother of God, and her role in salvation. The bishops spoke at length and beautifully about Mary. The Second Vatican Council asked Catholics to continue their devotion to Mary in relationship to Jesus and the Church.

During the Council the Pope met with about 2.300 bishops. It was then that the Pope asked all Catholics to call upon Mary often under her title, "Mother of the Church".
At the same time and at the same Council, the Pope reconsecrated the entire world to the Immaculate Heart of Mary. The Pope said that he was sending a golden rose to the sanctuary of Fatima, Portugal. The Pope himself would travel to Fatima later to pray there himself to the Mother of God.
