FULGENS CORONA -ENCYCLICAL OF POPE PIUS XII PROCLAIMING A MARIAN YEAR TO COMMEMORATE THE CENTENARY OF THE DEFINITION OF THE DOGMA OF THE IMMACULATE CONCEPTION:
1. The radiant crown of glory with which the most pure brow of the Virgin Mother was encircled by God, seems to Us to shine more brilliantly, as We recall to mind the day, on which, one hundred years ago, Our Predecessor of happy memory Pius IX, surrounded by a vast retinue of Cardinals and Bishops, with infallible apostolic authority defined, pronounced and solemnly sanctioned "that the doctrine, which holds that the Most Blessed Virgin Mary at the first moment of her conception was, by singular grace and privilege of the Omnipotent God, in virtue of the merits of Jesus Christ, Savior of the Human race, preserved from all stains of original sin, is revealed by God, and therefore to be firmly and resolutely believed by all the faithful." (Dogmatic bull Ineffabilis Deus, of Dec. 8, 1854.)
7. In the first place, the foundation of this doctrine is to be found in Sacred Scripture, where we are taught that God, Creator of all things, after the sad fall of Adam, addressed the serpent, the tempter and corrupter, in these words, which not a few Fathers, Doctors of the Church and many approved interpreters applied to the Virgin Mother of God: "I will put enmities between thee and the woman, and thy seed and her seed" (Gen. III-15). Now, if at any time the Blessed Mary were destitute of Divine grace even for the briefest moment, because of contamination in her conception by the hereditary stain of sin, there would not have come between her and the serpent that perpetual enmity spoken of from earliest tradition down to the time of the solemn definition of the Immaculate Conception, but rather a certain subjection.
8. Moreover, since the same holy Virgin is saluted "full of grace" and "blessed among women" (Luke I. 28, 24), by these words, as Catholic tradition has always interpreted, it is plainly indicated that "by this singular and solemn salutation, otherwise never heard of, it is shown that the Mother of God was the abode of all Divine graces, adorned with all the charisms of the Holy Spirit, yea, the treasury well nigh infinite and abyss inexhaustible of these charisms, so that she was never subjected to the one accursed" (Bull Ineffabilis Deus).
9. This doctrine, unanimously received in the early Church, has been handed down clearly enough by the Fathers, who claimed for the Blessed Virgin such titles as Lily Among Thorns; Land Wholly Intact; Immaculate; Always Blessed; Free From All Contagion Of Sin; Unfading Tree; Fountain Ever Clear; The One And Only Daughter Not Of Death But Of Life; Offspring Not Of Wrath But Of Grace; Unimpaired And Ever Unimpaired; Holy And Stranger To All Stain Of Sin; More Comely Than Comeliness Itself; More Holy Than Sanctity; Alone Holy Who, Excepting God, Is Higher Than All; By Nature More Beautiful, More Graceful And More Holy Than The Cherubim And Seraphim Themselves And The Whole Host Of Angels."
