YOUCAT Question n. 83 - Part II. What does the “Immaculate Conception of Mary” mean?

(Youcat answer - repeated) The Church believes that “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, Savior of the human race, preserved immune from all stain of original sin” (dogma of 1854).    

A deepening through CCC

(CCC 489b) Against all human expectation God chooses those who were considered powerless and weak to show forth his faithfulness to his promises: Hannah, the mother of Samuel; Deborah; Ruth; Judith and Esther; and many other women (Cf. 1 Cor 1:17; 1 Sam 1). Mary "stands out among the poor and humble of the Lord, who confidently hope for and receive salvation from him. After a long period of waiting the times are fulfilled in her, the exalted Daughter of Sion, and the new plan of salvation is established"(LG 55). (CCC 491) Through the centuries the Church has become ever more aware that Mary, "full of grace" through God  (Lk 1:28), 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, Savior of the human race, preserved immune from all stain of original sin (Pius IX, Ineffabilis Deus, 1854: DS 2803).   

Reflecting and meditating 

(Youcat comment) Belief in the Immaculate Conception has existed since the beginning of the Church. The expression is misunderstood today. It is saying that God preserved Mary from original sin from the very beginning. It says nothing about the conception of Jesus in Mary’s womb. By no means is it a devaluation of sexuality in Christianity, as though a husband and wife would be “stained” if they conceived a child.   

(CCC Comment)

(CCC 490) To become the mother of the Savior, Mary "was enriched by God with gifts appropriate to such a role" (LG 56). The angel Gabriel at the moment of the annunciation salutes her as "full of grace" (Lk 1:28). 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.
