Every day, from one end of the earth to the other, in the highest heights of the heavens and in the profoundest depths of the abysses, everything preaches, everything publishes, the admirable Mary! The nine choirs of angels, men of all ages, sexes, conditions and religions, the good and the bad, nay, even the devils themselves, willingly or unwillingly, are compelled by force of truth to call her Blessed. Saint Bonaventure tells us that all the angels in Heaven cry out incessantly to her: “Holy, holy, holy Mary, Mother of God and Virgin;” and that they offer to her millions and millions of times a day, the Angelical Salutation, Ave Maria, prostrating themselves before her, and begging of her in her graciousness to honor them with some of her commands. Even Saint Michael, as Saint Augustine says, although the prince of the heavenly court, is the most zealous in honoring her and causing her to be honored, and is always anxiously awaiting the honor of going at her bidding to render service to some of her servants.
The whole earth is full of her glory, especially among Christians, by whom she is taken as the protectress of many kingdoms, provinces, dioceses and cities. Many cathedrals are consecrated to God under her name. There are not some miraculous images where all sorts of evils are cured, and all sorts of good gifts obtained. Who can count the confraternities and congregations in her honor? How many religious orders have been founded in her name and under her protection? How many members in these confraternities, and how many religious men and women in all these orders, who publish her praises and confess her mercies! There is not a little child who, as it lisps the Hail Mary, does not praise her. There is scarcely a sinner who, even in his obduracy, has not some spark of confidence in her. Nay, the very devils in Hell respect her while they fear her
