Mary, also called St. Mary or the Virgin Mary, (flourished beginning of the Christian era), the mother of Jesus, venerated in the Christian church since the apostolic age and a favourite subject in Western art, music, and literature. Mary is known from biblical references, which are, however, too sparse to construct a coherent biography. The development of the doctrine of Mary can be traced through titles that have been ascribed to her in the history of the Christian communions—guarantee of the Incarnation, virgin mother, second Eve, mother of God, ever virgin, immaculate, and assumed into heaven. She has a number of feast days in various Christian traditions, several of which are holy days of obligation for Roman Catholics.

The New Testament account of her humility and obedience to the message of God have made her an exemplar for all ages of Christians. Out of the details supplied in the New Testament by the Gospels about the maid of Galilee, Christian piety and theology have constructed a picture of Mary that fulfills the prediction ascribed to her in the Magnificat (Luke 1:48): "Surely, from now on all generations will call me blessed."
