9 When we have recourse to Mary in prayer, we are having recourse to the Mother of mercy, who is so well disposed toward us that, whatever the necessity that presses upon us especially in attaining eternal life, she is instantly at our side of her own accord, even though she has not been invoked. She dispenses grace with a generous hand from that treasure with which from the beginning she was divinely endowed in fullest abundance that she might be worthy to be the Mother of God. By the fullness of grace which confers on her the most illustrious of her many titles, the Blessed Virgin is infinitely superior to all the hierarchies of men and angels, the one creature who is closest of all to Christ. "It is a great thing in any saint to have grace sufficient for the salvation of many souls; but to have enough to suffice for the salvation of everybody in the world, is the greatest of all; and this is found in Christ and in the Blessed Virgin."(1)
