Every year on December 8th, the Church celebrates the Solemnity of the Immaculate Conception of the Blessed Virgin Mary: The celebration that the Blessed Virgin Mary was conceived without original sin. From her conception, she was given a unique gift from God: the fullness of grace. This gift was necessary to freely answer the call to be the Mother of her Savior. The Eternal Father chose her “from before the foundation of the world, to be holy” (Ephesians 1:4). Knowing that her Son would redeem the world through His death and resurrection, the Father applied the gift of redemption to her at the moment of her conception. Therefore, benefitting from the fullness of grace, she remains free from sin her entire life, as a New Eve, Mother of Life Himself, and all the living, in the new creation, by the power of the Holy Spirit.
To understand this more deeply, we must look at the first Adam, the first Eve, the first creation, and the effect of man's lack of trust and disobedience on all their children. In the beginning, mankind was simply Adam and Eve. They were the entire human family, and humanity was very intimate with God. He was their Father, and they were His children. One day, Adam and Eve, with full knowledge and complete capacity to choose otherwise, disobeyed their Heavenly Father. They bought into the lies of the Devil and in a way became Satan’s children. Thus, in this single act, all of humanity was separated from their Father. One helpful way of looking at it is: Their inheritance was given away. A person cannot give what they do not have; thus all of their children are also missing this deep, intimate relationship with God, which only grace, God’s own life, can restore.
God promises to restore this relationship almost immediately after Adam and Eve sin against Him, or fall from grace. He promises in Genesis 3:15 that a woman would bear a Son who would crush the head of Satan, while Satan bites at His heel. The Father also says that He will place total and complete opposition between the Mother of the Child (who is Mary) and the Devil. The promise of crushing the head of Satan is fulfilled in the death and resurrection of our Lord Jesus Christ. Through the actions of Jesus, all sin is conquered, death loses its sting, and hell has no victory (see 1 Corinthians 15:55). Through this total and complete defeat of the powers of sin, death, and darkness, the grace of the total opposition to sin is granted to Mary, by the Father, in view of the death and resurrection of Christ, who would be her seed. Thus, through the obedience of the New Adam (who is Jesus) all can be saved (see Romans 5:19).
While this particular gift of grace given to the Virgin Mother of God is unique, it teaches us about ourselves and our relationship with God. We are children of Adam, and thus inherited a deep separation from God due to sin. Though He longed for us to return to Him, as a Father searches anxiously for His missing child, we were distant from Him. However, in Baptism we are conceived anew. The Blessed Virgin was restored to that deep
