[National Register] Mary was granted this extraordinary privilege because of her unique role in history as the mother of God. That is, she was preserved free from all stain of original sin from the very moment of her conception.
The Catechism of the Catholic Church explains that “to become the mother of the Savior, Mary ‘was enriched by God with gifts appropriate to such a role.’ The angel Gabriel at the moment of the annunciation salutes her as ‘full of grace.’ In fact, in order for Mary to be able to give the free assent of her faith to the announcement of her vocation, it was necessary that she be wholly borne by God’s grace” (No. 490).
“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,” the catechism states. “That is what the dogma of the Immaculate Conception confesses, as Pope Pius IX proclaimed in 1854” (No. 491).
