Lk 1, 39-56
During those days Mary set out and traveled to the hill country in haste to a town of Judah, where she entered the house of Zechariah and greeted Elizabeth. When Elizabeth heard Mary's greeting, the infant leaped in her womb, and Elizabeth, filled with the holy Spirit, cried out in a loud voice and said, "Most blessed are you among women, and blessed is the fruit of your womb. And how does this happen to me, that the mother of my Lord should come to me? For at the moment the sound of your greeting reached my ears, the infant in my womb leaped for joy. Blessed are you who believed that what was spoken to you by the Lord would be fulfilled."
And Mary said:
"My soul proclaims the greatness of the Lord; my spirit rejoices in God my Savior. For he has looked upon his handmaid's lowliness; behold, from now on will all ages call me blessed. The Mighty One has done great things for me, and Holy is his name.
His mercy is from age to age to those who fear him. He has shown might with his arm, dispersed the arrogant of mind and heart. He has thrown down the rulers from their thrones but lifted up the lowly. The hungry he has filled with good things; the rich he has sent away empty. He has helped Israel his servant, remembering his mercy, according to his promise to our fathers, to Abraham and to his descendants forever."
Mary remained with her about three months and then returned to her home.
Why does Mary have such a preeminent place in the communion of saints?
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. (972)
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.
