CATHOLIC CATECHISM

VIRGIN MARY IN THE BIBLE

The Gospel relates how the angel Gabriel appeared to virgin Mary, a twig from the root of king David. The angel announced she was to become pregnant by the Holy Spirit. She was to give birth to a son whose kingdom would last forever. Mary said: "I am the handmaid of the Lord. Let it be to me according to your word." Jesus was born in a stable in Bethlehem. Thus, God's eternal Word became man, and Mary became the mother of God.
In compliance with Jewish usage, the child was dedicated to God, and the priest said to Mary: "This child is destined to cause the falling and rising of many in Israel, and to be a sign that will be spoken against, so that the thoughts of many hearts will be revealed. And a sword will pierce your own soul too."
When Jesus was twelve years old, his parents and he went to Jerusalem for Passover. He got lost in the crowd. His parents found him in the temple, where the scribes were astonished at his clever answers. He went down with his parents and came to Nazareth, and was obedient to them; and his mother kept all these things in her heart.

The public life of Jesus begins when he is thirty years old, at the wedding in Cana. Mary is present too. She warns Jesus there is no more wine. Jesus shrugs his shoulders and says her concern doesn't affect him. But Mary says to the servants: "Do whatever Jesus tells you.". She knows that Jesus will from now on appear in full daylight.
When Jesus is hanging on the cross at Golgotha, his mother, Mary, and the disciple whom he loved, John, are standing there next each other. Then Jesus says to Mary, while pointing his chin to John: "Henceforth, this is your son." And to John: "This is your mother." Here John is representing all disciples. Therefore, Mary is our mother. We already saw she is among the apostles in the cenacle, when they receive the Holy Spirit.
