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.

11. And, since we were dealing with a matter of such great moment and of such importance, we considered it opportune to ask all our venerable brethren in the episcopate directly and authoritatively that each of them should make known to us his mind in a formal statement. Hence, on May 1, 1946, we gave them our letter “Deiparae Virginis Mariae,” a letter in which these words are contained: “Do you, venerable brethren, in your outstanding wisdom and prudence, judge that the bodily Assumption of the Blessed Virgin can be proposed and defined as a dogma of faith? Do you, with your clergy and people, desire it?”

12. But those whom “the Holy Spirit has placed as bishops to rule the Church of God” gave an almost unanimous affirmative response to both these questions. This “outstanding agreement of the Catholic prelates and the faithful,” affirming that the bodily Assumption of God’s Mother into heaven can be defined as a dogma of faith, since it shows us the concordant teaching of the Church’s ordinary doctrinal authority and the concordant faith of the Christian people which the same doctrinal authority sustains and directs, thus by itself and in an entirely certain and infallible way, manifests this privilege as a truth revealed by God and contained in that divine deposit which Christ has delivered to his Spouse to be guarded faithfully and to be taught infallibly. Certainly this teaching authority of the Church, not by any merely human effort but under the protection of the Spirit of Truth, and therefore absolutely without error, carries out the commission entrusted to it, that of preserving the revealed truths pure and entire throughout every age, in such a way that it presents them undefiled, adding nothing to them and taking nothing away from them. For, as the Vatican Council teaches, “the Holy Spirit was not promised to the successors of Peter in such a way that, by his revelation, they might manifest new doctrine, but so that, by his assistance, they might guard as sacred and might faithfully propose the revelation delivered through the apostles, or the deposit of faith.” Thus, from the universal agreement of the Church’s ordinary teaching authority we have a certain and firm proof, demonstrating that the Blessed Virgin Mary’s bodily Assumption into heaven- which surely no faculty of the human mind could know by its own natural powers, as far as the heavenly glorification of the virginal body of the loving Mother of God is concerned-is a truth that has been revealed by God and consequently something that must be firmly and faithfully believed by all children of the Church. For, as the Vatican Council asserts, “all those things are to be believed by divine and Catholic faith which are contained in the written Word of God or in Tradition, and which are proposed by the Church, either in solemn judgment or in its ordinary and universal teaching office, as divinely revealed truths which must be believed.”

13. Various testimonies, indications and signs of this common belief of the Church are evident from remote times down through the course of the centuries; and this same belief becomes more clearly manifest from day to day.

14. Christ’s faithful, through the teaching and the leadership of their pastors, have learned from the sacred books that the Virgin Mary, throughout the course of her earthly pilgrimage, led a life troubled by cares, hardships, and sorrows, and that, moreover, what the holy old man Simeon had foretold actually came to pass, that is, that a terribly sharp sword pierced her heart as she stood under the cross of her divine Son, our Redeemer. In the same way, it was not difficult for them to admit that the great Mother of God, like her only begotten Son, had actually passed from this life. But this in no way prevented them from believing and from professing openly that her sacred body had never been subject to the corruption of the tomb, and that the august tabernacle of the Divine Word had never been reduced to dust and ashes. Actually, enlightened by divine grace and moved by affection for her, God’s Mother and our own dearest Mother, they have contemplated in an ever clearer light the wonderful harmony and order of those privileges which the most provident God has lavished upon this loving associate of our Redeemer, privileges which reach such an exalted plane that, except for her, nothing created by God other than the human nature of Jesus Christ has ever reached this level.

15. The innumerable temples which have been dedicated to the Virgin Mary assumed into heaven clearly attest this faith. So do those sacred images, exposed therein for the veneration of the faithful, which bring this unique triumph of the Blessed Virgin before the eyes of all men. Moreover, cities, dioceses, and individual regions have been placed under the special patronage and guardianship of the Virgin Mother of God assumed into heaven. In the same way, religious institutes, with the approval of the Church, have been founded and have taken their name from this privilege. Nor can we pass over in silence the fact that in the Rosary of Mary, the recitation of which this Apostolic See so urgently recommends, there is one mystery proposed for pious meditation which, as all know, deals with the Blessed Virgin’s Assumption into heaven.

16. This belief of the sacred pastors and of Christ’s faithful is universally manifested still more splendidly by the fact that, since ancient times, there have been both in the East and in the West solemn liturgical offices commemorating this privilege. 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.”

17. In the liturgical books which deal with the feast either of the dormition or of the Assumption of the Blessed Virgin there are expressions that agree in testifying that, when the Virgin Mother of God passed from this earthly exile to heaven, what happened to her sacred body was, by the decree of divine Providence, in keeping with the dignity of the Mother of the Word Incarnate, and with the other privileges she had been accorded. Thus, to cite an illustrious example, this is set forth in that sacramentary which Adrian I, our predecessor of immortal memory, sent to the Emperor Charlemagne. These words are found in this volume: “Venerable to us, O Lord, is the festivity of this day on which the holy Mother of God suffered temporal death, but still could not be kept down by the bonds of death, who has begotten your Son our Lord incarnate from herself.”

18. What is here indicated in that sobriety characteristic of the Roman liturgy is presented more clearly and completely in other ancient liturgical books. To take one as an example, the Gallican sacramentary designates this privilege of Mary’s as “an ineffable mystery all the more worthy of praise as the Virgin’s Assumption is something unique among men.” And, in the Byzantine liturgy, not only is the Virgin Mary’s bodily Assumption connected time and time again with the dignity of the Mother of God, but also with the other privileges, and in particular with the virginal motherhood granted her by a singular decree of God’s Providence. “God, the King of the universe, has granted you favors that surpass nature. As he kept you a virgin in childbirth, thus he has kept your body incorrupt in the tomb and has glorified it by his divine act of transferring it from the tomb.”

19. The fact that the Apostolic See, which has inherited the function entrusted to the Prince of the Apostles, the function of confirming the brethren in the faith, has by its own authority, made the celebration of this feast ever more solemn, has certainly and effectively moved the attentive minds of the faithful to appreciate always more completely the magnitude of the mystery it commemorates. So it was that the Feast of the Assumption was elevated from the rank which it had occupied from the beginning among the other Marian feasts to be classed among the more solemn celebrations of the entire liturgical cycle. And, when our predecessor St. Sergius I prescribed what is known as the litany, or the stational procession, to be held on four Marian feasts, he specified together the Feasts of the Nativity, the Annunciation, the Purification, and the Dormition of the Virgin Mary. Again, St. Leo IV saw to it that the feast, which was already being celebrated under the title of the Assumption of the Blessed Mother of God, should be observed in even a more solemn way when he ordered a vigil to be held on the day before it and prescribed prayers to be recited after it until the octave day. When this had been done, he decided to take part himself in the celebration, in the midst of a great multitude of the faithful. Moreover, the fact that a holy fast had been ordered from ancient times for the day prior to the feast is made very evident by what our predecessor St. Nicholas I testifies in treating of the principal fasts which “the Holy Roman Church has observed for a long time, and still observes.”

20. However, since the liturgy of the Church does not engender the Catholic faith, but rather springs from it, in such a way that the practices of the sacred worship proceed from the faith as the fruit comes from the tree, it follows that the holy Fathers and the great Doctors, in the homilies and sermons they gave the people on this feast day, did not draw their teaching from the feast itself as from a primary source, but rather they spoke of this doctrine as something already known and accepted by Christ’s faithful. They presented it more clearly. They offered more profound explanations of its meaning and nature, bringing out into sharper light the fact that this feast shows, not only that the dead body of the Blessed Virgin Mary remained incorrupt, but that she gained a triumph out of death, her heavenly glorification after the example of her only begotten Son, Jesus Christ-truths that the liturgical books had frequently touched upon concisely and briefly.

21. Thus St. John Damascene, an outstanding herald of this traditional truth, spoke out with powerful eloquence when he compared the bodily Assumption of the loving Mother of God with her other prerogatives and privileges. “It was fitting that she, who had kept her virginity intact in childbirth, should keep her own body free from all corruption even after death. It was fitting that she, who had carried the Creator as a child at her breast, should dwell in the divine tabernacles. It was fitting that the spouse, whom the Father had taken to himself, should live in the divine mansions. It was fitting that she, who had seen her Son upon the cross and who had thereby received into her heart the sword of sorrow which she had escaped in the act of giving birth to him, should look upon him as he sits with the Father. It was fitting that God’s Mother should possess what belongs to her Son, and that she should be honored by every creature as the Mother and as the handmaid of God.”

22. These words of St. John Damascene agree perfectly with what others have taught on this same subject. Statements no less clear and accurate are to be found in sermons delivered by Fathers of an earlier time or of the same period, particularly on the occasion of this feast. And so, to cite some other examples, St. Germanus of Constantinople considered the fact that the body of Mary, the virgin Mother of God, was incorrupt and had been taken up into heaven to be in keeping, not only with her divine motherhood, but also with the special holiness of her virginal body. “You are she who, as it is written, appears in beauty, and your virginal body is all holy, all chaste, entirely the dwelling place of God, so that it is henceforth completely exempt from dissolution into dust. Though still human, it is changed into the heavenly life of incorruptibility, truly living and glorious, undamaged and sharing in perfect life.” And another very ancient writer asserts: “As the most glorious Mother of Christ, our Savior and God and the giver of life and immortality, has been endowed with life by him, she has received an eternal incorruptibility of the body together with him who has raised her up from the tomb and has taken her up to himself in a way known only to him.”

23. When this liturgical feast was being celebrated ever more widely and with ever increasing devotion and piety, the bishops of the Church and its preachers in continually greater numbers considered it their duty openly and clearly to explain the mystery that the feast commemorates, and to explain how it is intimately connected with the other revealed truths.

24. Among the scholastic theologians there have not been lacking those who, wishing to inquire more profoundly into divinely revealed truths and desirous of showing the harmony that exists between what is termed the theological demonstration and the Catholic faith, have always considered it worthy of note that this privilege of the Virgin Mary’s Assumption is in wonderful accord with those divine truths given us in Holy Scripture.

25. When they go on to explain this point, they adduce various proofs to throw light on this privilege of Mary. 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.

26. Often there are theologians and preachers who, following in the footsteps of the holy Fathers, have been rather free in their use of events and expressions taken from Sacred Scripture to explain their belief in the Assumption. Thus, to mention only a few of the texts rather frequently cited in this fashion, some have employed the words of the psalmist: “Arise, O Lord, into your resting place: you and the ark, which you have sanctified”; and have looked upon the Ark of the Covenant, built of incorruptible wood and placed in the Lord’s temple, as a type of the most pure body of the Virgin Mary, preserved and exempt from all the corruption of the tomb and raised up to such glory in heaven. Treating of this subject, they also describe her as the Queen entering triumphantly into the royal halls of heaven and sitting at the right hand of the divine Redeemer. Likewise they mention the Spouse of the Canticles “that goes up by the desert, as a pillar of smoke of aromatical spices, of myrrh and frankincense” to be crowned. These are proposed as depicting that heavenly Queen and heavenly Spouse who has been lifted up to the courts of heaven with the divine Bridegroom.

27. Moreover, the scholastic Doctors have recognized the Assumption of the Virgin Mother of God as something signified, not only in various figures of the Old Testament, but also in that woman clothed with the sun whom John the Apostle contemplated on the Island of Patmos. Similarly they have given special attention to these words of the New Testament: “Hail, full of grace, the Lord is with you, blessed are you among women,” since they saw, in the mystery of the Assumption, the fulfillment of that most perfect grace granted to the Blessed Virgin and the special blessing that countered the curse of Eve.

28. Thus, during the earliest period of scholastic theology, that most pious man, Amadeus, Bishop of Lausarme, held that the Virgin Mary’s flesh had remained incorrupt-for it is wrong to believe that her body has seen corruption-because it was really united again to her soul and, together with it, crowned with great glory in the heavenly courts. “For she was full of grace and blessed among women. She alone merited to conceive the true God of true God, whom as a virgin, she brought forth, to whom as a virgin she gave milk, fondling him in her lap, and in all things she waited upon him with loving care.”

29. Among the holy writers who at that time employed statements and various images and analogies of Sacred Scripture to Illustrate and to confirm the doctrine of the Assumption, which was piously believed, the Evangelical Doctor, St. Anthony of Padua, holds a special place. On the feast day of the Assumption, while explaining the prophet’s words: “I will glorify the place of my feet,” he stated it as certain that the divine Redeemer had bedecked with supreme glory his most beloved Mother from whom he had received human flesh. He asserts that “you have here a clear statement that the Blessed Virgin has been assumed in her body, where was the place of the Lord’s feet. Hence it is that the holy Psalmist writes: ‘Arise, O Lord, into your resting place: you and the ark which you have sanctified.”‘ And he asserts that, just as Jesus Christ has risen from the death over which he triumphed and has ascended to the right hand of the Father, so likewise the ark of his sanctification “has risen up, since on this day the Virgin Mother has been taken up to her heavenly dwelling.”

30. When, during the Middle Ages, scholastic theology was especially flourishing, St. Albert the Great who, to establish this teaching, had gathered together many proofs from Sacred Scripture, from the statements of older writers, and finally from the liturgy and from what is known as theological reasoning, concluded in this way: “From these proofs and authorities and from many others, it is manifest that the most blessed Mother of God has been assumed above the choirs of angels. And this we believe in every way to be true.” And, in a sermon which he delivered on the sacred day of the Blessed Virgin Mary’s annunciation, explained the words “Hail, full of grace”-words used by the angel who addressed her-the Universal Doctor, comparing the Blessed Virgin with Eve, stated clearly and incisively that she was exempted from the fourfold curse that had been laid upon Eve.

31. Following the footsteps of his distinguished teacher, the Angelic Doctor, despite the fact that he never dealt directly with this question, nevertheless, whenever he touched upon it, always held together with the Catholic Church, that Mary’s body had been assumed into heaven along with her soul.

32. Along with many others, the Seraphic Doctor held the same views. He considered it as entirely certain that, as God had preserved the most holy Virgin Mary from the violation of her virginal purity and integrity in conceiving and in childbirth, he would never have permitted her body to have been resolved into dust and ashes. Explaining these words of Sacred Scripture: “Who is this that comes up from the desert, flowing with delights, leaning upon her beloved?” and applying them in a kind of accommodated sense to the Blessed Virgin, he reasons thus: “From this we can see that she is there bodily…her blessedness would not have been complete unless she were there as a person. The soul is not a person, but the soul, joined to the body, is a person. It is manifest that she is there in soul and in body. Otherwise she would not possess her complete beatitude.

33. In the fifteenth century, during a later period of scholastic theology, St. Bernardine of Siena collected and diligently evaluated all that the medieval theologians had said and taught on this question. He was not content with setting down the principal considerations which these writers of an earlier day had already expressed, but he added others of his own. The likeness between God’s Mother and her divine Son, in the way of the nobility and dignity of body and of soul-a likeness that forbids us to think of the heavenly Queen as being separated from the heavenly Kingmakes it entirely imperative that Mary “should be only where Christ is.” Moreover, it is reasonable and fitting that not only the soul and body of a man, but also the soul and body of a woman should have obtained heavenly glory. 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.

34. The above-mentioned teachings of the holy Fathers and of the Doctors have been in common use during more recent times. Gathering together the testimonies of the Christians of earlier days, St. Robert Bellarmine exclaimed: “And who, I ask, could believe that the ark of holiness, the dwelling place of the Word of God, the temple of the Holy Spirit, could be reduced to ruin? My soul is filled with horror at the thought that this virginal flesh which had begotten God, had brought him into the world, had nourished and carried him, could have been turned into ashes or given over to be food for worms.”

35. In like manner St. Francis of Sales, after asserting that it is wrong to doubt that Jesus Christ has himself observed, in the most perfect way, the divine commandment by which children are ordered to honor their parents, asks this question: “What son would not bring his mother back to life and would not bring her into paradise after her death if he could?” And St. Alphonsus writes that “Jesus did not wish to have the body of Mary corrupted after death, since it would have redounded to his own dishonor to have her virginal flesh, from which he himself had assumed flesh, reduced to dust.”

36. Once the mystery which is commemorated in this feast had been placed in its proper light, there were not lacking teachers who, instead of dealing with the theological reasonings that show why it is fitting and right to believe the bodily Assumption of the Blessed Virgin Mary into heaven, chose to focus their mind and attention on the faith of the Church itself, which is the Mystical Body of Christ without stain or wrinkle and is called by the Apostle “the pillar and ground of truth.” Relying on this common faith, they considered the teaching opposed to the doctrine of our Lady’s Assumption as temerarious, if not heretical. Thus, like not a few others, St. Peter Canisius, after he had declared that the very word “assumption” signifies the glorification, not only of the soul but also of the body, and that the Church has venerated and has solemnly celebrated this mystery of Mary’s Assumption for many centuries, adds these words of warning: “This teaching has already been accepted for some centuries, it has been held as certain in the minds of the pious people, and it has been taught to the entire Church in such a way that those who deny that Mary’s body has been assumed into heaven are not to be listened to patiently but are everywhere to be denounced as over-contentious or rash men, and as imbued with a spirit that is heretical rather than Catholic.”

37. At the same time the great Suarez was professing in the field of mariology the norm that “keeping in mind the standards of propriety, and when there is no contradiction or repugnance on the part of Scripture, the mysteries of grace which God has wrought in the Virgin must be measured, not by the ordinary laws, but by the divine omnipotence.” Supported by the common faith of the entire Church on the subject of the mystery of the Assumption, he could conclude that this mystery was to be believed with the same firmness of assent as that given to the Immaculate Conception of the Blessed Virgin. Thus he already held that such truths could be defined.

38. 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.

39. We must remember especially that, since the second century, the Virgin Mary has been designated by the holy Fathers as the new Eve, who, although subject to the new Adam, is most intimately associated with him in that struggle against the infernal foe which, as foretold in the protoevangelium, would finally result in that most complete victory over the sin and death which are always mentioned together in the writings of the Apostle of the Gentiles. Consequently, just as the glorious resurrection of Christ was an essential part and the final sign of this victory, so that struggle which was common to the Blessed Virgin and her divine Son should be brought to a close by the glorification of her virginal body, for the same Apostle says: “When this mortal thing hath put on immortality, then shall come to pass the saying that is written: Death is swallowed up in victory.”

40. Hence the revered Mother of God, from all eternity joined in a hidden way with Jesus Christ in one and the same decree of predestination, immaculate in her conception, a most perfect virgin in her divine motherhood, the noble associate of the divine Redeemer who has won a complete triumph over sin and its consequences, finally obtained, as the supreme culmination of her privileges, that she should be preserved free from the corruption of the tomb and that, like her own Son, having overcome death, she might be taken up body and soul to the glory of heaven where, as Queen, she sits in splendor at the right hand of her Son, the immortal King of the Ages.

41. 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.

42. We, who have placed our pontificate under the special patronage of the most holy Virgin, to whom we have had recourse so often in times of grave trouble, we who have consecrated the entire human race to her Immaculate Heart in public ceremonies, and who have time and time again experienced her powerful protection, are confident that this solemn proclamation and definition of the Assumption will contribute in no small way to the advantage of human society, since it redounds to the glory of the Most Blessed Trinity, to which the Blessed Mother of God is bound by such singular bonds. It is to be hoped that all the faithful will be stirred up to a stronger piety toward their heavenly Mother, and that the souls of all those who glory in the Christian name may be moved by the desire of sharing in the unity of Jesus Christ’s Mystical Body and of increasing their love for her who shows her motherly heart to all the members of this august body. And so we may hope that those who meditate upon the glorious example Mary offers us may be more and more convinced of the value of a human life entirely devoted to carrying out the heavenly Father’s will and to bringing good to others. Thus, while the illusory teachings of materialism and the corruption of morals that follows from these teachings threaten to extinguish the light of virtue and to ruin the lives of men by exciting discord among them, in this magnificent way all may see clearly to what a lofty goal our bodies and souls are destined. 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.

43. We rejoice greatly that this solemn event falls, according to the design of God’s providence, during this Holy Year, so that we are able, while the great Jubilee is being observed, to adorn the brow of God’s Virgin Mother with this brilliant gem, and to leave a monument more enduring than bronze of our own most fervent love for the Mother of God.

44. 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.

45. Hence if anyone, which God forbid, should dare willfully to deny or to call into doubt that which we have defined, let him know that he has fallen away completely from the divine and Catholic Faith.

46. In order that this, our definition of the bodily Assumption of the Virgin Mary into heaven may be brought to the attention of the universal Church, we desire that this, our Apostolic Letter, should stand for perpetual remembrance, commanding that written copies of it, or even printed copies, signed by the hand of any public notary and bearing the seal of a person constituted in ecclesiastical dignity, should be accorded by all men the same reception they would give to this present letter, were it tendered or shown.

47. It is forbidden to any man to change this, our declaration, pronouncement, and definition or, by rash attempt, to oppose and counter it. If any man should presume to make such an attempt, let him know that he will incur the wrath of Almighty God and of the Blessed Apostles Peter and Paul.

48. Given at Rome, at St. Peter’s, in the year of the great Jubilee, 1950, on the first day of the month of November, on the Feast of All Saints, in the twelfth year of our pontificate.

I, PIUS, Bishop of the Catholic Church, have signed, so defining.

2. And indeed it was wholly fitting that so wonderful a mother should be ever resplendent with the glory of most sublime holiness and so completely free from all taint of original sin that she would triumph utterly over the ancient serpent. To her did the Father will to give his only-begotten Son — the Son whom, equal to the Father and begotten by him, the Father loves from his heart — and to give this Son in such a way that he would be the one and the same common Son of God the Father and of the Blessed Virgin Mary. It was she whom the Son himself chose to make his Mother and it was from her that the Holy Spirit willed and brought it about that he should be conceived and born from whom he himself proceeds.

3. The Catholic Church, directed by the Holy Spirit of God, is the pillar and base of truth and has ever held as divinely revealed and as contained in the deposit of heavenly revelation this doctrine concerning the original innocence of the august Virgin — a doctrine which is so perfectly in harmony with her wonderful sanctity and preeminent dignity as Mother of God — and thus has never ceased to explain, to teach and to foster this doctrine age after age in many ways and by solemn acts. From this very doctrine, flourishing and wondrously propagated in the Catholic world through the efforts and zeal of the bishops, was made very clear by the Church when she did not hesitate to present for the public devotion and veneration of the faithful the Feast of the Conception of the Blessed Virgin. By this most significant fact, the Church made it clear indeed that the conception of Mary is to be venerated as something extraordinary, wonderful, eminently holy, and different from the conception of all other human beings — for the Church celebrates only the feast days of the saints.

4. And hence the very words with which the Sacred Scriptures speak of Uncreated Wisdom and set forth his eternal origin, the Church, both in its ecclesiastical offices and in its liturgy, has been wont to apply likewise to the origin of the Blessed Virgin, inasmuch as God, by one and the same decree, had established the origin of Mary and the Incarnation of Divine Wisdom.

5. These truths, so generally accepted and put into practice by the faithful, indicate how zealously the Roman Church, mother and teacher of all Churches, has continued to teach this doctrine of the Immaculate Conception of the Virgin. Yet the more important actions of the Church deserve to be mentioned in detail. For such dignity and authority belong to the Church that she alone is the center of truth and of Catholic unity. It is the Church in which alone religion has been inviolably preserved and from which all other Churches must receive the tradition of the Faith.

6. The same Roman Church, therefore, desired nothing more than by the most persuasive means to state, to protect, to promote and to defend the doctrine of the Immaculate Conception. This fact is most clearly shown to the whole world by numerous and significant acts of the Roman Pontiffs, our predecessors. To them, in the person of the Prince of the Apostles, were divinely entrusted by Christ our Lord, the charge and supreme care and the power of feeding the lambs and sheep; in particular, of confirming their brethren, and of ruling and governing the universal Church.

7. Our predecessors, indeed, by virtue of their apostolic authority, gloried in instituting the Feast of the Conception in the Roman Church. They did so to enhance its importance and dignity by a suitable Office and Mass, whereby the prerogative of the Virgin, her exception from the hereditary taint, was most distinctly affirmed. As to the homage already instituted, they spared no effort to promote and to extend it either by the granting of indulgences, or by allowing cities, provinces and kingdoms to choose as their patroness God’s own Mother, under the title of “The Immaculate Conception.” Again, our predecessors approved confraternities, congregations and religious communities founded in honor of the Immaculate Conception, monasteries, hospitals, altars, or churches; they praised persons who vowed to uphold with all their ability the doctrine of the Immaculate Conception of the Mother of God. Besides, it afforded the greatest joy to our predecessors to ordain that the Feast of the Conception should be celebrated in every church with the very same honor as the Feast of the Nativity; that it should be celebrated with an octave by the whole Church; that it should be reverently and generally observed as a holy day of obligation; and that a pontifical Capella should be held in our Liberian pontifical basilica on the day dedicated to the conception of the Virgin. Finally, in their desire to impress this doctrine of the Immaculate Conception of the Mother of God upon the hearts of the faithful, and to intensify the people’s piety and enthusiasm for the homage and the veneration of the Virgin conceived without the stain of original sin, they delighted to grant, with the greatest pleasure, permission to proclaim the Immaculate Conception of the Virgin in the Litany of Loreto, and in the Preface of the Mass, so that the rule of prayer might thus serve to illustrate the rule of belief. Therefore, we ourselves, following the procedure of our predecessors, have not only approved and accepted what had already been established, but bearing in mind, moreover, the decree of Sixtus IV, have confirmed by our authority a proper Office in honor of the Immaculate Conception, and have with exceeding joy extended its use to the universal Church.

8. Now inasmuch as whatever pertains to sacred worship is intimately connected with its object and cannot have either consistency or durability if this object is vague or uncertain, our predecessors, the Roman Pontiffs, therefore, while directing all their efforts toward an increase of the devotion to the conception, made it their aim not only to emphasize the object with the utmost zeal, but also to enunciate the exact doctrine. Definitely and clearly they taught that the feast was held in honor of the conception of the Virgin. They denounced as false and absolutely foreign to the mind of the Church the opinion of those who held and affirmed that it was not the conception of the Virgin but her sanctification that was honored by the Church. They never thought that greater leniency should be extended toward those who, attempting to disprove the doctrine of the Immaculate Conception of the Virgin, devised a distinction between the first and second instance of conception and inferred that the conception which the Church celebrates was not that of the first instance of conception but the second. In fact, they held it was their duty not only to uphold and defend with all their power the Feast of the Conception of the Blessed Virgin but also to assert that the true object of this veneration was her conception considered in its first instant. Hence the words of one of our predecessors, Alexander VII, who authoritatively and decisively declared the mind of the Church: “Concerning the most Blessed Virgin Mary, Mother of God, ancient indeed is that devotion of the faithful based on the belief that her soul, in the first instant of its creation and in the first instant of the soul’s infusion into the body, was, by a special grace and privilege of God, in view of the merits of Jesus Christ, her Son and the Redeemer of the human race, preserved free from all stain of original sin. And in this sense have the faithful ever solemnized and celebrated the Feast of the Conception.”

9. Moreover, our predecessors considered it their special solemn duty with all diligence, zeal, and effort to preserve intact the doctrine of the Immaculate Conception of the Mother of God. For, not only have they in no way ever allowed this doctrine to be censured or changed, but they have gone much further and by clear statements repeatedly asserted that the doctrine by which we profess the Immaculate Conception of the Virgin is on its own merits entirely in harmony with the ecclesiastical veneration; that it is ancient and widespread, and of the same nature as that which the Roman Church has undertaken to promote and to protect, and that it is entirely worthy to be used in the Sacred Liturgy and solemn prayers. Not content with this they most strictly prohibited any opinion contrary to this doctrine to be defended in public or private in order that the doctrine of the Immaculate Conception of the Virgin might remain inviolate. By repeated blows they wished to put an end to such an opinion. And lest these oft-repeated and clearest statements seem useless, they added a sanction to them.

10. All these things our illustrious predecessor, Alexander VII, summed up in these words: “We have in mind the fact that the Holy Roman Church solemnly celebrated the Feast of the Conception of the undefiled and ever-Virgin Mary, and has long ago appointed for this a special and proper Office according to the pious, devout, and laudable instruction which was given by our predecessor, Sixtus IV. Likewise, we were desirous, after the example of our predecessors, to favor this praiseworthy piety, devotion, feast and veneration — a veneration which is in keeping with the piety unchanged in the Roman Church from the day it was instituted. We also desired to protect this piety and devotion of venerating and extolling the most Blessed Virgin preserved from original sin by the grace of the Holy Spirit. Moreover, we were anxious to preserve the unity of the Spirit in the bond of peace in the flock of Christ by putting down arguments and controversies and by removing scandals. So at the instance and request of the bishops mentioned above, with the chapters of the churches, and of King Philip and his kingdoms, we renew the Constitutions and Decrees issued by the Roman Pontiffs, our predecessors, especially Sixtus IV, Paul V, and Gregory XV, in favor of the doctrine asserting that the soul of the Blessed Virgin, in its creation and infusion into the body, was endowed with the grace of the Holy Spirit and preserved from original sin; and also in favor of the feast and veneration of the conception of the Virgin Mother of God, which, as is manifest, was instituted in keeping with that pious belief. So we command this feast to be observed under the censures and penalties contained in the same Constitutions.

11. “And therefore, against all and everyone of those who shall continue to construe the said Constitutions and Decrees in a manner apt to frustrate the favor which is thereby given to the said doctrine, and to the feast and relative veneration, or who shall dare to call into question the said sentence, feast and worship, or in any way whatever, directly or indirectly, shall declare themselves opposed to it under any pretext whatsoever, were it but only to the extent of examining the possibilities of effecting the definition, or who shall comment upon and interpret the Sacred Scripture, or the Fathers or Doctors in connection therewith, or finally, for any reason, or on any occasion, shall dare, either in writing or verbally, to speak, preach, treat, dispute or determine upon, or assert whatsoever against the foregoing matters, or who shall adduce any arguments against them, while leaving them unresolved, or who shall disagree therewith in any other conceivable manner, we hereby declare that in addition to the penalties and censures contained in the Constitutions issued by Sixtus IV to which we want them to be subjected and to which we subject them by the present Constitution, we hereby decree that they be deprived of the authority of preaching, reading in public, that is to say teaching and interpreting; and that they be also deprived ipso facto of the power of voting, either actively or passively, in all elections, without the need for any further declaration; and that also, ipso facto, without any further declaration, they shall incur the penalty of perpetual disability from preaching, reading in public, teaching and interpreting, and that it shall not be possible to absolve them from such penalty, or remove it, save through ourselves, or the Roman Pontiffs who shall succeed us.

12. “We also require that the same shall remain subject to any other penalties which by us, of our own free will — or by the Roman Pontiffs, our successors (according as they may decree) — shall be deemed advisable to establish, and by the present Constitution we declare them subject thereto, and hereby renew the above Decrees and Constitutions of Paul V and Gregory XV.

13. “Moreover, as regards those books in which the said sentence, feast and relative veneration are called into question or are contradicted in any way whatsoever, according to what has already been stated, either in writing or verbally, in discourses, sermons, lectures, treatises and debates — that may have been printed after the above-praised Decree of Paul V, or may be printed hereafter we hereby prohibit them, subject to the penalties and censures established by the Index of prohibited books, and ipso facto, without any further declaration, we desire and command that they be held as expressly prohibited.”

14. All are aware with how much diligence this doctrine of the Immaculate Conception of the Mother of God has been handed down, proposed and defended by the most outstanding religious orders, by the more celebrated theological academies, and by very eminent doctors in the sciences of theology. All know, likewise, how eager the bishops have been to profess openly and publicly, even in ecclesiastical assemblies, that Mary, the most holy Mother of God, by virtue of the foreseen merits of Christ, our Lord and Redeemer, was never subject to original sin, but was completely preserved from the original taint, and hence she was redeemed in a manner more sublime.

15. Besides, we must note a fact of the greatest importance indeed. Even the Council of Trent itself, when it promulgated the dogmatic decree concerning original sin, following the testimonies of the Sacred Scriptures, of the Holy Fathers and of the renowned Council, decreed and defined that all men are born infected by original sin; nevertheless, it solemnly declared that it had no intention of including the blessed and immaculate Virgin Mary, the Mother of God, in this decree and in the general extension of its definition. Indeed, considering the times and circumstances, the Fathers of Trent sufficiently intimated by this declaration that the Blessed Virgin Mary was free from the original stain; and thus they clearly signified that nothing could be reasonably cited from the Sacred Scriptures, from Tradition, or from the authority of the Fathers, which would in any way be opposed to so great a prerogative of the Blessed Virgin.

16. And indeed, illustrious documents of venerable antiquity, of both the Eastern and the Western Church, very forcibly testify that this doctrine of the Immaculate Conception of the most Blessed Virgin, which was daily more and more splendidly explained, stated and confirmed by the highest authority, teaching, zeal, knowledge, and wisdom of the Church, and which was disseminated among all peoples and nations of the Catholic world in a marvelous manner — this doctrine always existed in the Church as a doctrine that has been received from our ancestors, and that has been stamped with the character of revealed doctrine. For the Church of Christ, watchful guardian that she is, and defender of the dogmas deposited with her, never changes anything, never diminishes anything, never adds anything to them; but with all diligence she treats the ancient documents faithfully and wisely; if they really are of ancient origin and if the faith of the Fathers has transmitted them, she strives to investigate and explain them in such a way that the ancient dogmas of heavenly doctrine will be made evident and clear, but will retain their full, integral, and proper nature, and will grown only within their own genus — that is, within the same dogma, in the same sense and the same meaning.

17. The Fathers and writers of the Church, well versed in the heavenly Scriptures, had nothing more at heart than to vie with one another in preaching and teaching in many wonderful ways the Virgin’s supreme sanctity, dignity, and immunity from all stain of sin, and her renowned victory over the most foul enemy of the human race. This they did in the books they wrote to explain the Scriptures, to vindicate the dogmas, and to instruct the faithful. These ecclesiastical writers in quoting the words by which at the beginning of the world God announced his merciful remedies prepared for the regeneration of mankind — words by which he crushed the audacity of the deceitful serpent and wondrously raised up the hope of our race, saying, “I will put enmities between you and the woman, between your seed and her seed” — taught that by this divine prophecy the merciful Redeemer of mankind, Jesus Christ, the only begotten Son of God, was clearly foretold: That his most Blessed Mother, the Virgin Mary, was prophetically indicated; and, at the same time, the very enmity of both against the evil one was significantly expressed. Hence, just as Christ, the Mediator between God and man, assumed human nature, blotted the handwriting of the decree that stood against us, and fastened it triumphantly to the cross, so the most holy Virgin, united with him by a most intimate and indissoluble bond, was, with him and through him, eternally at enmity with the evil serpent, and most completely triumphed over him, and thus crushed his head with her immaculate foot.

18. This sublime and singular privilege of the Blessed Virgin, together with her most excellent innocence, purity, holiness and freedom from every stain of sin, as well as the unspeakable abundance and greatness of all heavenly graces, virtues and privileges — these the Fathers beheld in that ark of Noah, which was built by divine command and escaped entirely safe and sound from the common shipwreck of the whole world; in the ladder which Jacob saw reaching from the earth to heaven, by whose rungs the angels of God ascended and descended, and on whose top the Lord himself leaned’ in that bush which Moses saw in the holy place burning on all sides, which was not consumed or injured in any way but grew green and blossomed beautifully; in that impregnable tower before the enemy, from which hung a thousand bucklers and all the armor of the strong; in that garden enclosed on all sides, which cannot be violated or corrupted by any deceitful plots; as in that resplendent city of God, which has its foundations on the holy mountains; in that most august temple of God, which, radiant with divine splendors, is full of the glory of God; and in very many other biblical types of this kind. In such allusions the Fathers taught that the exalted dignity of the Mother of God, her spotless innocence and her sanctity unstained by any fault, had been prophesied in a wonderful manner.

19. In like manner did they use the words of the prophets to describe this wondrous abundance of divine gifts and the original innocence of the Virgin of whom Jesus was born. They celebrated the august Virgin as the spotless dove, as the holy Jerusalem, as the exalted throne of God, as the ark and house of holiness which Eternal Wisdom built, and as that Queen who, abounding in delights and leaning on her Beloved, came forth from the mouth of the Most High, entirely perfect, beautiful, most dear to God and never stained with the least blemish.

20. When the Fathers and writers of the Church meditated on the fact that the most Blessed Virgin was, in the name and by order of God himself, proclaimed full of grace by the Angel Gabriel when he announced her most sublime dignity of Mother of God, they thought that this singular and solemn salutation, never heard before, showed that the Mother of God is the seat of all divine graces and is adorned with all gifts of the Holy Spirit. To them Mary is an almost infinite treasury, an inexhaustible abyss of these gifts, to such an extent that she was never subject to the curse and was, together with her Son, the only partaker of perpetual benediction. Hence she was worthy to hear Elizabeth, inspired by the Holy Spirit, exclaim: “Blessed are you among women, and blessed is the fruit of your womb.”

21. Hence, it is the clear and unanimous opinion of the Fathers that the most glorious Virgin, for whom “he who is mighty has done great things,” was resplendent with such an abundance of heavenly gifts, with such a fullness of grace and with such innocence, that she is an unspeakable miracle of God — indeed, the crown of all miracles and truly the Mother of God; that she approaches as near to God himself as is possible for a created being; and that she is above all men and angels in glory. Hence, to demonstrate the original innocence and sanctity of the Mother of God, not only did they frequently compare her to Eve while yet a virgin, while yet innocence, while yet incorrupt, while not yet deceived by the deadly snares of the most treacherous serpent; but they have also exalted her above Eve with a wonderful variety of expressions. Eve listened to the serpent with lamentable consequences; she fell from original innocence and became his slave. The most Blessed Virgin, on the contrary, ever increased her original gift, and not only never lent an ear to the serpent, but by divinely given power she utterly destroyed the force and dominion of the evil one.

22. Accordingly, the Fathers have never ceased to call the Mother of God the lily among thorns, the land entirely intact, the Virgin undefiled, immaculate, ever blessed, and free from all contagion of sin, she from whom was formed the new Adam, the flawless, brightest, and most beautiful paradise of innocence, immortality and delights planted by God himself and protected against all the snares of the poisonous serpent, the incorruptible wood that the worm of sin had never corrupted, the fountain ever clear and sealed with the power of the Holy Spirit, the most holy temple, the treasure of immortality, the one and only daughter of life — not of death — the plant not of anger but of grace, through the singular providence of God growing ever green contrary to the common law, coming as it does from a corrupted and tainted root.

23. As if these splendid eulogies and tributes were not sufficient, the Fathers proclaimed with particular and definite statements that when one treats of sin, the holy Virgin Mary is not even to be mentioned; for to her more grace was given than was necessary to conquer sin completely. They also declared that the most glorious Virgin was Reparatrix of the first parents, the giver of life to posterity; that she was chosen before the ages, prepared for himself by the Most High, foretold by God when he said to the serpent, “I will put enmities between you and the woman.” - Unmistakable evidence that she crushed the poisonous head of the serpent. And hence they affirmed that the Blessed Virgin was, through grace, entirely free from every stain of sin, and from all corruption of body, soul and mind; that she was always united with God and joined to him by an eternal covenant; that she was never in darkness but always in light; and that, therefore, she was entirely a fit habitation for Christ, not because of the state of her body, but because of her original grace.

24. To these praises they have added very noble words. Speaking of the conception of the Virgin, they testified that nature yielded to grace and, unable to go on, stood trembling. The Virgin Mother of God would not be conceived by Anna before grace would bear its fruits; it was proper that she be conceived as the first-born, by whom “the first-born of every creature” would be conceived. They testified, too, that the flesh of the Virgin, although derived from Adam, did not contract the stains of Adam, and that on this account the most Blessed Virgin was the tabernacle created by God himself and formed by the Holy Spirit, truly a work in royal purple, adorned and woven with gold, which that new Beseleel made. They affirmed that the same Virgin is, and is deservedly, the first and especial work of God, escaping the fiery arrows of the evil one; that she is beautiful by nature and entirely free from all stain; that at her Immaculate Conception she came into the world all radiant like the dawn. For it was certainly not fitting that this vessel of election should be wounded by the common injuries, since she, differing so much from the others, had only nature in common with them, not sin. In fact, it was quite fitting that, as the Only-Begotten has a Father in heaven, whom the Seraphim extol as thrice holy, so he should have a Mother on earth who would never be without the splendor of holiness.

25. This doctrine so filled the minds and souls of our ancestors in the faith that a singular and truly marvelous style of speech came into vogue among them. They have frequently addressed the Mother of God as immaculate, as immaculate in every respect; innocent, and verily most innocent; spotless, and entirely spotless; holy and removed from every stain of sin; all pure, all stainless, the very model of purity and innocence; more beautiful than beauty, more lovely than loveliness; more holy than holiness, singularly holy and most pure in soul and body; the one who surpassed all integrity and virginity; the only one who has become the dwelling place of all the graces of the most Holy Spirit. God alone excepted, Mary is more excellent than all, and by nature fair and beautiful, and more holy than the Cherubim and Seraphim. To praise her all the tongues of heaven and earth do not suffice.

26. Everyone is cognizant that this style of speech has passed almost spontaneously into the books of the most holy liturgy and the Offices of the Church, in which they occur so often and abundantly. In them, the Mother of God is invoked and praised as the one spotless and most beautiful dove, as a rose ever blooming, as perfectly pure, ever immaculate, and ever blessed. She is celebrated as innocence never sullied and as the second Eve who brought forth the Emmanuel.

27. No wonder, then, that the Pastors of the Church and the faithful gloried daily more and more in professing with so much piety, religion, and love this doctrine of the Immaculate Conception of the Virgin Mother of God, which, as the Fathers discerned, was recorded in the Divine Scriptures; which was handed down in so many of their most important writings; which was expressed and celebrated in so many illustrious monuments of venerable antiquity; which was proposed and confirmed by the official and authoritative teaching of the Church. Hence, nothing was dearer, nothing more pleasing to these pastors than to venerate, invoke, and proclaim with most ardent affection the Virgin Mother of God conceived without original stain. Accordingly, from ancient times the bishops of the Church, ecclesiastics, religious orders, and even emperors and kings, have earnestly petitioned this Apostolic See to define a dogma of the Catholic Faith the Immaculate Conception of the most holy Mother of God. These petitions were renewed in these our own times; they were especially brought to the attention of Gregory XVI, our predecessor of happy memory, and to ourselves, not only by bishops, but by the secular clergy and religious orders, by sovereign rulers and by the faithful.

28. Mindful, indeed, of all these things and considering them most attentively with particular joy in our heart, as soon as we, by the inscrutable design of Providence, had been raised to the sublime Chair of St. Peter — in spite of our unworthiness — and had begun to govern the universal Church, nothing have we had more at heart — a heart which from our tenderest years has overflowed with devoted veneration and love for the most Blessed Virgin — than to show forth her prerogatives in resplendent light.

29. That we might proceed with great prudence, we established a special congregation of our venerable brethren, the cardinals of the holy Roman Church, illustrious for their piety, wisdom, and knowledge of the sacred scriptures. We also selected priests, both secular and regular, well trained in the theological sciences, that they should most carefully consider all matters pertaining to the Immaculate Conception of the Virgin and make known to us their opinion.

30. Although we knew the mind of the bishops from the petitions which we had received from them, namely, that the Immaculate Conception of the Blessed Virgin be finally defined, nevertheless, on February 2, 1849, we sent an Encyclical Letter from Gaeta to all our venerable brethren, the bishops of the Catholic world, that they should offer prayers to God and then tell us in writing what the piety an devotion of their faithful was in regard to the Immaculate Conception of the Mother of God. We likewise inquired what the bishops themselves thought about defining this doctrine and what their wishes were in regard to making known with all possible solemnity our supreme judgment.

31. We were certainly filled with the greatest consolation when the replies of our venerable brethren came to us. For, replying to us with a most enthusiastic joy, exultation and zeal, they not only again confirmed their own singular piety toward the Immaculate Conception of the most Blessed Virgin, and that of the secular and religious clergy and of the faithful, but with one voice they even entreated us to define our supreme judgment and authority the Immaculate Conception of the Virgin. In the meantime we were indeed filled with no less joy when, after a diligent examination, our venerable brethren, the cardinals of the special congregation and the theologians chosen by us as counselors (whom we mentioned above), asked with the same enthusiasm and fervor for the definition of the Immaculate Conception of the Mother of God.

32. Consequently, following the examples of our predecessors, and desiring to proceed in the traditional manner, we announced and held a consistory, in which we addressed our brethren, the cardinals of the Holy Roman Church. It was the greatest spiritual joy for us when we heard them ask us to promulgate the dogmatic definition of the Immaculate Conception of the Virgin Mother of God.

33. Therefore, having full trust in the Lord that the opportune time had come for defining the Immaculate Conception of the Blessed Virgin Mary, Mother of God, which Holy Scripture, venerable Tradition, the constant mind of the Church, the desire of Catholic bishops and the faithful, and the memorable Acts and Constitutions of our predecessors, wonderfully illustrate and proclaim, and having most diligently considered all things, as we poured forth to God ceaseless and fervent prayers, we concluded that we should no longer delay in decreeing and defining by our supreme authority the Immaculate Conception of the Blessed Virgin. And thus, we can satisfy the most holy desire of the Catholic world as well as our own devotion toward the most holy Virgin, and at the same time honor more and more the only begotten Son, Jesus Christ our Lord through his holy Mother — since whatever honor and praise are bestowed on the Mother redound to the Son.

34. Wherefore, in humility and fasting, we unceasingly offered our private prayers as well as the public prayers of the Church to God the Father through his Son, that he would deign to direct and strengthen our mind by the power of the Holy Spirit. In like manner did we implore the help of the entire heavenly host as we ardently invoked the Paraclete. Accordingly, by the inspiration of the Holy Spirit, for the honor of the Holy and undivided Trinity, for the glory and adornment of the Virgin Mother of God, for the exaltation of the Catholic Faith, and for the furtherance of the Catholic religion, by the authority of Jesus Christ our Lord, of the Blessed Apostles Peter and Paul, and by our own: “We declare, pronounce, and define that the doctrine which holds that the most Blessed Virgin Mary, in the first instance of her conception, by a singular grace and privilege granted by Almighty God, in view of the merits of Jesus Christ, the Savior of the human race, was preserved free from all stain of original sin, is a doctrine revealed by God and therefore to be believed firmly and constantly by all the faithful.”

35. Hence, if anyone shall dare — which God forbid! — to think otherwise than as has been defined by us, let him know and understand that he is condemned by his own judgment; that he has suffered shipwreck in the faith; that he has separated from the unity of the Church; and that, furthermore, by his own action he incurs the penalties established by law if he should dare to express in words or writing or by any other outward means the errors he thinks in his heart.

36.Our soul overflows with joy and our tongue with exultation. We give, and we shall continue to give, the humblest and deepest thanks to Jesus Christ, our Lord, because through his singular grace he has granted to us, unworthy though we be, to decree and offer this honor and glory and praise to his most holy Mother. All our hope do we repose in the most Blessed Virgin — in the all fair and immaculate one who has crushed the poisonous head of the most cruel serpent and brought salvation to the world: in her who is the glory of the prophets and apostles, the honor of the martyrs, the crown and joy of all the saints; in her who is the safest refuge and the most trustworthy helper of all who are in danger; in her who, with her only-begotten Son, is the most powerful Mediatrix and Conciliatrix in the whole world; in her who is the most excellent glory, ornament, and impregnable stronghold of the holy Church; in her who has destroyed all heresies and snatched the faithful people and nations from all kinds of direst calamities; in her do we hope who has delivered us from so many threatening dangers. We have, therefore, a very certain hope and complete confidence that the most Blessed Virgin will ensure by her most powerful patronage that all difficulties be removed and all errors dissipated, so that our Holy Mother the Catholic Church may flourish daily more and more throughout all the nations and countries, and may reign “from sea to sea and from the river to the ends of the earth,” and may enjoy genuine peace, tranquility and liberty. We are firm in our confidence that she will obtain pardon for the sinner, health for the sick, strength of heart for the weak, consolation for the afflicted, help for those in danger; that she will remove spiritual blindness from all who are in error, so that they may return to the path of truth and justice, and that here may be one flock and one shepherd.

37. Let all the children of the Catholic Church, who are so very dear to us, hear these words of ours. With a still more ardent zeal for piety, religion and love, let them continue to venerate, invoke and pray to the most Blessed Virgin Mary, Mother of God, conceived without original sin. Let them fly with utter confidence to this most sweet Mother of mercy and grace in all dangers, difficulties, needs, doubts and fears. Under her guidance, under her patronage, under her kindness and protection, nothing is to be feared; nothing is hopeless. Because, while bearing toward us a truly motherly affection and having in her care the work of our salvation, she is solicitous about the whole human race. And since she has been appointed by God to be the Queen of heaven and earth, and is exalted above all the choirs of angels and saints, and even stands at the right hand of her only-begotten Son, Jesus Christ our Lord, she presents our petitions in a most efficacious manner. What she asks, she obtains. Her pleas can never be unheard.
