Pope Pius XII - 1950
1. The most bountiful God, who is almighty, the plan of whose providence rests upon wisdom and love, tempers, in the secret purpose of his own mind, the sorrows of peoples and of individual men by means of joys that he interposes in their lives from time to time, in such a way that, under different conditions and in different ways, all things may work together unto good for those who love him.
2. Now, just like the present age, our pontificate is weighed down by ever so many cares, anxieties, and troubles, by reason of very severe calamities that have taken place and by reason of the fact that many have strayed away from truth and virtue. Nevertheless, we are greatly consoled to see that, while the Catholic faith is being professed publicly and vigorously, piety toward the Virgin Mother of God is flourishing and daily growing more fervent, and that almost everywhere on earth it is showing indications of a better and holier life. Thus, while the Blessed Virgin is fulfilling in the most affectionate manner her maternal duties on behalf of those redeemed by the blood of Christ, the minds and the hearts of her children are being vigorously aroused to a more assiduous consideration of her prerogatives.
3. Actually God, who from all eternity regards Mary with a most favorable and unique affection, has “when the fullness of time came” put the plan of his providence into effect in such a way that all the privileges and prerogatives he had granted to her in his sovereign generosity were to shine forth in her in a kind of perfect harmony. And, although the Church has always recognized this supreme generosity and the perfect harmony of graces and has daily studied them more and more throughout the course of the centuries, still it is in our own age that the privilege of the bodily Assumption into heaven of Mary, the Virgin Mother of God, has certainly shone forth more clearly.
4. That privilege has shone forth in new radiance since our predecessor of immortal memory, Pius IX, solemnly proclaimed the dogma of the loving Mother of God’s Immaculate Conception. These two privileges are most closely bound to one another. Christ overcame sin and death by his own death, and one who through Baptism has been born again in a supernatural way has conquered sin and death through the same Christ. Yet, according to the general rule, God does not will to grant to the just the full effect of the victory over death until the end of time has come. And so it is that the bodies of even the just are corrupted after death, and only on the last day will they be joined, each to its own glorious soul.
5. Now God has willed that the Blessed Virgin Mary should be exempted from this general rule. She, by an entirely unique privilege, completely overcame sin by her Immaculate Conception, and as a result she was not subject to the law of remaining in the corruption of the grave, and she did not have to wait until the end of time for the redemption of her body.
6. Thus, when it was solemnly proclaimed that Mary, the Virgin Mother of God, was from the very beginning free from the taint of original sin, the minds of the faithful were filled with a stronger hope that the day might soon come when the dogma of the Virgin Mary’s bodily Assumption into heaven would also be defined by the Church’s supreme teaching authority.
7. Actually it was seen that not only individual Catholics, but also those who could speak for nations or ecclesiastical provinces, and even a considerable number of the Fathers of the Vatican Council, urgently petitioned the Apostolic See to this effect.
8. During the course of time such postulations and petitions did not decrease but rather grew continually in number and in urgency. In this cause there were pious crusades of prayer. Many outstanding theologians eagerly and zealously carried out investigations on this subject either privately or in public ecclesiastical institutions and in other schools where the sacred disciplines are taught. Marian Congresses, both national and international in scope, have been held in many parts of the Catholic world. These studies and investigations have brought out into even clearer light the fact that the dogma of the Virgin Mary’s Assumption into heaven is contained in the deposit of Christian faith entrusted to the Church. They have resulted in many more petitions, begging and urging the Apostolic See that this truth be solemnly defined.
9. In this pious striving, the faithful have been associated in a wonderful way with their own holy bishops, who have sent petitions of this kind, truly remarkable in number, to this See of the Blessed Peter. Consequently, when we were elevated to the throne of the supreme pontificate, petitions of this sort had already been addressed by the thousands from every part of the world and from every class of people, from our beloved sons the Cardinals of the Sacred College, from our venerable brethren, archbishops and bishops, from dioceses and from parishes.
10. Consequently, while we sent up earnest prayers to God that he might grant to our mind the light of the Holy Spirit, to enable us to make a decision on this most serious subject, we issued special orders in which we commanded that, by corporate effort, more advanced inquiries into this matter should be begun and that, in the meantime, all the petitions about the Assumption of the Blessed Virgin Mary into heaven which had been sent to this Apostolic See from the time of Pius IX, our predecessor of happy memory, down to our own days should be gathered together and carefully evaluated.
