Munificentissimus Deus: Defining the Dogma of the Assumption by Pope Pius XII

(Rome: Vatican, 1950), 24

The holy Fathers and Doctors of the Church have never failed to draw enlightenment from this fact since, as everyone knows, the sacred liturgy, "because it is the profession, subject to the supreme teaching authority within the Church, of heavenly truths, can supply proofs and testimonies of no small value for deciding a particular point of Christian doctrine." (16)
This privilege of the Virgin Mary's Assumption is in wonderful accord with those divine truths given us in Holy Scripture. (24)
As the first element of these demonstrations, they insist upon the fact that, out of filial love for his mother, Jesus Christ has willed that she be assumed into heaven. They base the strength of their proofs on the incomparable dignity of her divine motherhood and of all those prerogatives which follow from it. These include her exalted holiness, entirely surpassing the sanctity of all men and of the angels, the intimate union of Mary with her Son, and the affection of preeminent love which the Son has for his most worthy Mother. (25)
Finally, since the Church has never looked for the bodily relics of the Blessed Virgin nor proposed them for the veneration of the people, we have a proof on the order of a sensible experience. (33)
All these proofs and considerations of the holy Fathers and the theologians are based upon the Sacred Writings as their ultimate foundation. These set the loving Mother of God as it were before our very eyes as most intimately joined to her divine Son and as always sharing his lot. Consequently it seems impossible to think of her, the one who conceived Christ, brought him forth, nursed him with her milk, held him in her arms, and clasped him to her breast, as being apart from him in body, even though not in soul, after this earthly life. Since our Redeemer is the Son of Mary, he could not do otherwise, as the perfect observer of God's law, than to honor, not only his eternal Father, but also his most beloved Mother. And, since it was within his power to grant her this great honor, to preserve her from the corruption of the tomb, we must believe that he really acted in this way. (38)
Since the universal Church, within which dwells the Spirit of Truth who infallibly directs it toward an ever more perfect knowledge of the revealed truths, has expressed its own belief many times over the course of the centuries, and since the bishops of the entire world are almost unanimously petitioning that the truth of the bodily Assumption of the Blessed Virgin Mary into heaven should be defined as a dogma of divine and Catholic faith--this truth which is based on the Sacred Writings, which is thoroughly rooted in the minds of the faithful, which has been approved in ecclesiastical worship from the most remote times, which is completely in harmony with the other revealed truths, and which has been expounded and explained magnificently in the work, the science, and the wisdom of the theologians - we believe that the moment appointed in the plan of divine providence for the solemn proclamation of this outstanding privilege of the Virgin Mary has already arrived. (41)
Finally it is our hope that belief in Mary's bodily Assumption into heaven will make our belief in our own resurrection stronger and render it more effective. (42)
For which reason, after we have poured forth prayers of supplication again and again to God, and have invoked the light of the Spirit of Truth, for the glory of Almighty God who has lavished his special affection upon the Virgin Mary, for the honor of her Son, the immortal King of the Ages and the Victor over sin and death, for the increase of the glory of that same august Mother, and for the joy and exultation of the entire Church; by the authority of our Lord Jesus Christ, of the Blessed Apostles Peter and Paul, and by our own authority, we pronounce, declare, and define it to be a divinely revealed dogma: that the Immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory.
