In the Book of Genesis God tells Adam: "You may freely eat of every tree of the garden; but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you will die" (Gen 2: 16-17) This instruction is reported, by Eve, to the serpent: "God said, 'You shall not eat of the fruit of the tree that is in the middle of the garden, nor shall you touch it, or you shall die'." (Gen 4: 3) There does seem to be some uncertainty here as to whether eating of the fruit will cause instantaneous death or merely in the future. It is possible that there is a translation issue due to the verbal constructions of Hebrew which, I am told, does not have a dedicated future tense. This leads to the prophetic present where a meaning can be both in the present and referring to the future, e.g. "Look, the young woman (Gk virgin) is with child and shall bear a son, and you will name him Immanuel." (Is 7: 14). In any event the serpent replies, calling God a liar: "You will not die." (Gen 3: 4) Yet Adam does die, even though it is at the age of nine hundred years (Gen 5: 5) There is no biblical record of when Eve died.
It is clear, from the biblical account, that the Fall has implications both physically and spiritually for the couple who have eaten of the forbidden fruit. To Eve: "I will greatly increase your pangs in childbearing; in pain you shall bring forth children, yet your desire shall be for your husband, and he shall rule over you" (Gen 3: 16) To Adam God says: "... cursed is the ground because of you; in toil you shall eat of it all the days of your life; thorns and thistles it shall bring forth for you and you shall eat the plants of the field. By the sweat of your face you shall eat bread until you return to the ground, for out of it you were taken; you are dust and to dust you shall return." (Gen 3: 17-18) The phenomenon of death is brought about through sin: "Therefore, just as sin came into the world though one man, and death came through sin, and so death spread to all because all have sinned..." (Rm 5: 12) Paul also tells us that the end of sin is death: "For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord." (Rm 6: 22)
Our Lady, the Church tells us as dogma and she testifies to herself in her apparitions to St Bernadette at Lourdes, is the Immaculate Conception. She was not affected by Original Sin and consequently not subject to the curses brought about through that act of disobedience. As a result, her ability to respond obediently to God's will for her was not impeded by the weakening of the will and the distortion of the intellect brought about by Original Sin and continuing in concupiscence for those who are baptized. It means that she is not affected by death in the same way that the rest of the human race is. Hence, the Eastern Churches talk about the Dormition of Our Lady since she fell asleep. She did not die in the sense that we know it with the dissolution of the body and separation of body from soul.
Born from the womb of the Immaculate Conception and conceived by the Holy Spirit, Jesus was also not affected by Original Sin, which is hereditary. Nevertheless, he is fully human: "For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who in every respect has been tested as we are, yet without sin." (4: 15) It is through him that the curse of unending death is overturned: "For since death came through a human being, the resurrection of the dead has also come through a human being; for as all die in Adam, so will all be made alive in Christ." (1 Cor 15: 21-22) It is on account of his resurrection that we long to be freed from the sentence of death and corruption brought about through sin: "... for the creation was subjected to futility, not of its own will but by the will of the one who subjected it, in hope that the creation itself will be set free from its bondage to decay and will obtain the glory of the children on God." (1 Cor 8: 20-22).
Our Lady was not only free of Original Sin but in her obedience to God she was free from personal sin. She is Immaculate in her conception and in her personal conduct. This is all brought about through the plan and grace of God. however, her freedom remained. Her "fiat" - "Here am I, the servant of the Lord; let it be with me according to your word" (Lk 1: 38) - is a constitutive element of the life of the Church. In her person she serves, as the Preface for the Assumption states: "... as the beginning and image of your Church's coming to perfection." Her glorification, body and spirit, we pray will also be ours as a fulfilment of God's salvific plan: "We know that all things work together for good for those who love God, who are called according to his purpose. For those whom he foreknew he also predestined to be confirmed to the image of his Son, in order that he might be the firstborn within a large family. And those whom he predestined he also called; and those whom he called he also justified; and those whom he justified he also glorified." (Rom 8: 28-30)
What else can we say of the Assumption of Our Lady? What does this glorification look like? St Paul reassures the Thessalonians that all of the faithful will ultimately be joined with the Lord in a resurrected state whether they are alive or dead when he returns in glory: "For the Lord himself, with a cry of command, with the archangel's call and with the sound of God's trumpet, will descend from heaven, and the dead in Christ will rise first. Then we who are alive, who are left, will be caught up in the clouds together with them to meet the Lord in the air, and so we will be with the Lord forever." (1 Thess 4: 16-17) In my opinion, if we look at the Shroud of Turin, we can see how the body, wrapped in the linen cloth, de-materialized leaving behind the three-dimensional image left on the tendrils of the linen. If Our Lady had been wrapped in a linen cloth after she "fell asleep" we would have similar artifact with her image imprinted on it in a three-dimensional photographic negative. She experienced this grace, to share fully in the resurrection, on account of her sinless state which precluded the consequences of physical death. Thus, crowned as Queen of Heaven, the lowly "handmaid of the Lord" is able to intercede for all those of her children in the Church who call upon her, asking for her aid.
