YOUCAT Question n. 147 - Why does Mary have such a preeminent place in the communion of saints?

(Youcat answer) Mary is the Mother of God. She was united with Jesus on earth as no other human being was or could be — in an intimacy that does not cease in heaven. Mary is the Queen of Heaven, and in her motherhood she is quite close to us.   

A deepening through CCC

(CCC 972) After speaking of the Church, her origin, mission, and destiny, we can find no better way to conclude than by looking to Mary. In her we contemplate what the Church already is in her mystery on her own "pilgrimage of faith," and what she will be in the homeland at the end of her journey. There, "in the glory of the Most Holy and Undivided Trinity," "in the communion of all the saints" (LG 69). The Church is awaited by the one she venerates as Mother of her Lord and as her own mother. In the meantime the Mother of Jesus, in the glory which she possesses in body and soul in heaven, is the image and beginning of the Church as it is to be perfected in the world to come. Likewise she shines forth on earth until the day of the Lord shall come, a sign of certain hope and comfort to the pilgrim People of God (LG 68; cf. 2 Pet 3:10).    

Reflecting and meditating 

(Youcat comment) Because she committed herself, body and soul, to a divine yet dangerous undertaking, Mary was taken up body and soul into heaven. Anyone who lives and believes as Mary did will get to heaven.  

(CCC Comment)

(CCC 975) "We believe that the Holy Mother of God, the new Eve, Mother of the Church, continues in heaven to exercise her maternal role on behalf of the members of Christ" (Paul VI, CPG § 15).

(The next question is:  Can Mary really help us?)
