Concerning the end of Mary's earthly life, the Council uses the terms of the Bull defining the dogma of Assumption and states: "The Immaculate Virgin, preserved free from all stain of original-sin, was taken up body and soul into heavenly glory, when her earthly life was over." (LG, 59) With this formula, the Dogmatic Constitution Lumen gentium, following my Venerable Predecessor Pius XII, made no pronouncement on the question of Mary's death. Nevertheless, Pius XII did not intend to deny the fact of her death, but merely did not judge it opportune to affirm solemnly the death of the Mother of God as a truth to be accepted by all believers.
Christ made death a means of salvation
Some theologians have in fact maintained that the Blessed Virgin did not die and was immediately raised from earthly life to heavenly glory. However, this opinion was unknown until the 17th century, whereas a common tradition actually exists which sees Mary's death as her entry into heavenly glory.
Could Mary of Nazareth have experienced the drama of death in her own flesh? Reflecting on Mary's destiny and her relationship with her divine Son, it seems legitimate to answer in the affirmative: since Christ died, it would be difficult to maintain the contrary for his Mother.
The Fathers of the Church, who had no doubts in this regard, reasoned along these lines. One need only quote St. Jacob of Sarug (521), who wrote that when the time came for Mary "to walk on the way of all generations," the way, that is, of death, "the group of the Twelve Apostles" gathered to bury "the virginal body of the Blessed One." St. Modestus of Jerusalem (634), after a lengthy discussion of "the most blessed dormition of the most glorious Mother of God," ends his eulogy by exalting the miraculous intervention of Christ who "raised her from the tomb," to take her up with him in glory. St. John Damascene (704) for his part asks: "Why is it that she who in giving birth surpassed all limits of nature should now bend to its laws, and her immaculate body be subjected to death?" And he answers: "To be clothed in immortality, it is of course necessary that the mortal part be shed, since even the master of nature did not refuse the experience of death. Indeed, he died according to the flesh and by dying destroyed death; on corruption he bestowed incorruption and made death the source of resurrection."
It is true that in Revelation death is presented as a punishment for sin. However, the fact that the Church proclaims Mary free from original sin by a unique divine privilege does not lead to the conclusion that she also received physical immortality. The Mother is not superior to the Son who underwent death, giving it a new meaning and changing it into a means of salvation.
The New Testament provides no information on the circumstances of Mary's death. This silence lends one to suppose that it happened naturally, with no detail particularly worthy of mention. If this were not the case, how could the information about it have remained hidden from her contemporaries and not have been passed down to us in some way?
As to the cause of Mary's death, the opinions that wish to exclude her from death by natural causes seem groundless. It is more important to look for the Blessed Virgin's spiritual attitude at the moment of her departure from this world. In this regard, St. Francis de Sales maintains that Mary's death was due to a transport of love. He speaks of a dying "in love, from love and through love," going so far as to say that the Mother of God died of love for her Son Jesus.
Mary's death was an event of love
Whatever from the physical point of view was the organic, biological cause of the end of her bodily life, it can be said that for Mary the passage from this life to the next was the full development of grace in glory, so that no death can ever be so fittingly described as a "dormition" as hers.
In some of the writings of the Church Fathers we find Jesus himself described as coming to take his Mother at the time of her death to bring her into heavenly glory. In this way they present the death of Mary as an event of love which conducted her to her divine Son to share his immortal life. At the end of her earthly life, she must have experienced, like Paul and more strongly, the desire to be freed from her body in order to be with Christ forever. (cf Phil 1:23).
This experience of death personally enriched the Blessed Virgin: by undergoing mankind's common destiny, she can more effectively exercise her spiritual motherhood towards those approaching the last moment of their life.
