And who amongst the saints is as powerful with God as his most holy Mother? She obtains all that she pleases. “You willest,” says St. Bermard, “and all is done.” St. Peter Damian even says, “that when Mary asks graces from God, she does not ask, but, so to say, commands, for her Son honors her by refusing her nothing.” Thus does the Son honor his beloved Mother by granting her whatever she asks, even in favor of sinners. Hence, St. Germanus says, “Thou, O Mother of God, art omnipotent to save sinners, and needest no other recommendation with God, for thou art the Mother of true life.”
O Mary, thou canst make me a saint; I rely on thee.
