Mary was created only for God
21. Let us not imagine, then, as some misguided teachers do, that Mary being simply a creature would be a hindrance to union with the Creator. Far from it, for it is no longer Mary who lives but Jesus Christ himself, God alone, who lives in her. Her transformation into God far surpasses that experienced by St Paul and other saints, more than heaven surpasses the earth. Mary was created only for God, and it is unthinkable that she should reserve even one soul for herself. On the contrary she leads every soul to God and to union with him. Mary is the wonderful echo of God. The more a person joins himself to her, the more effectively she unites him to God. When we say "Mary", she re-echoes "God". When, like St Elizabeth, we call her blessed, she gives the honour to God. If those misguided ones who were so sadly led astray by the devil, even in their prayer-life, had known how to discover Mary, and Jesus through her, and God through Jesus, they would not have had such terrible falls. The saints tell us that when we have once found Mary, and through Mary Jesus, and through Jesus God the Father, then we have discovered every good. When we say "every good", we except nothing. "Every good" includes every grace, continuous friendship with God, every protection against the enemies of God, possession of truth to counter every falsehood, endless benefits and unfailing headway against the hazards we meet on the way to salvation, and finally every consolation and joy amid the bitter afflictions of life.
22. This does not mean that one who has discovered Mary through a genuine devotion is exempt from crosses and sufferings. Far from it! One is tried even more than others, because Mary, as Mother of the living, gives to all her children splinters of the tree of life, which is the Cross of Jesus. But while meting out crosses to them she gives the grace to bear them with patience, and even with joy. In this way, the crosses she sends to those who trust themselves to her are rather like sweetmeats, i.e. "sweetened" crosses rather than "bitter" ones. If from time to time they do taste the bitterness of the chalice from which we must drink to become proven friends of God, the consolation and joy which their Mother sends in the wake of their sorrows creates in them a strong desire to carry even heavier and still more bitter crosses.
