Preparing a Tabernacle for the Lord

            In the Catechism of the Catholic Church we learn about the Immaculate Conception of the Blessed Virgin Mary, which we celebrate this Tuesday, December 8:

Through the centuries the Church has become ever more aware that Mary, ‘full of grace’ through God, was redeemed from the moment of her conception. That is what the dogma of the Immaculate Conception confesses, as Pope Pius IX proclaimed in 1854: ‘The most Blessed Virgin Mary was, from the first moment of her conception, by a singular grace and privilege of almighty God and by virtue of the merits of Jesus Christ, Saviour of the human race, preserved immune from all stain of original sin’ (CCC 491).
            Original sin isn’t an actual sin that any of us committed; instead, original sin refers to the actual first sin of Adam and Eve, our first parents, who disobeyed God because, in their pride, they listened to the temptation of Satan, “No, you shall not die the death. For God doth know that in what day soever you shall eat thereof, your eyes shall be opened: and you shall be as Gods, knowing good and evil.” The had already been created by God “to our image and likeness,” but they wanted to be like God without God, or to take God’s place in their own lives. The result of this original sin was the death of the life of God in their souls, what the Catechism calls “the grace of original holiness” (CCC 399). 
            As children of Adam and Eve we are born outside of grace and the friendship of God. However, the Son of God, who is “God from God, light from light, true God from true God,” came to restore us to grace and to the friendship and love of God, and He was born of the Blessed Virgin Mary, the Mother of God. The Church Fathers saw Jesus Christ as a new Adam, come to undo the disobedience of Adam through His own obedience to the Cross. In the same way, they saw the Blessed Virgin as a new Eve. 
            St. Irenaeus of Lyons wrote, “And thus also it was that the know of Eve’s disobedience was loosed by the obedience of Mary. For what the virgin Eve had bound through unbelief, this did the virgin Mary set free through faith” (Against Heresies 3, 22, 4).
            Again, St. Aelred wrote, “Once we lay in death, as you know and believe, in sin, in darkness, in misery. In death, because we had lost the Lord; in sin, because of our corruption; in darkness, for we were without the light of wisdom, and thus had perished utterly. But then we were born, far better than through Eve, through Mary the blessed, because Christ was born of her. We have recovered new life in place of sin, immortality instead of mortality, light in place of darkness. She is our mother – the mother of our life, the mother of our incarnation, the mother of our light” (Sermon 20, in Nativitate beatae Mariae).
            The Blessed Virgin was conceived without original sin because she was “full of grace” from the moment of her conception, because she was to carry in her womb the One who would be a blessing to the entire world.
            Finally, as Saint Sophronius wrote “Enclosed within your womb in God himself. He makes his abode in you and comes forth from you like a bridegroom, winning joy for all and bestowing God’s light on all” (Oratio 2, in sanctissimae Deiparae Annuntiatione).
