Lives of the Saints, by Alban Butler, Benziger Bros. ed. , at sacred-texts.com
THIS festival was appointed by Pope Innocent XI., that on it the faithful may be called upon in a particular manner to recommend to God, through the intercession of the Blessed Virgin, the necessities of His Church, and to return Him thanks for His gracious protection and numberless mercies. What gave occasion to the institution of this feast was a solemn thanksgiving for the relief of Vienna when it was besieged by the Turks in 1683. If we desire to deprecate the divine anger, justly provoked by our sins, with our prayers, we must join the tears of sincere compunction
with a perfect conversion of our manners. The first grace we should always beg of God is that He will bring us to the disposition of condign penance. Our supplications for the divine mercies, and our thanksgivings for benefits received, will only thus be rendered acceptable. By no other means can we deserve the blessing of God, or be recommended to it by the patronage of His holy mother. To the invocation of Jesus it is a pious and wholesome practice to join our application to the Blessed Virgin, that, through her intercession, we may more easily and more abundantly obtain the effects of our petitions. In this sense devout souls pronounce, with great affection and confidence, the holy names of Jesus and Mary.
