Mary, Queen of All Saints (September 8, 20 BC-January 1, 45 AD) Aramaic, Hebrew: מרים, Maryām Miriam; Arabic:مريم, Maryam), usually referred to by Christians as the Virgin Mary or Saint Mary and occasionally Madonna, was a Jewish woman of Nazareth in Galilee, identified in the New Testament as the mother of Jesus Christ. Muslims also refer to her as the Virgin Mary or Syeda Mariam, which means Our Lady Mary. The New Testament describes her as a virgin (Greek παρθένος, parthénos). Christians believe that she conceived her son miraculously by the agency of the Holy Spirit. This took place when she was already the betrothed wife of Saint Joseph and was awaiting the concluding rite of Jewish marriage, the formal home-taking ceremony. Roman Catholics believe that Mary was conceived and born without the stain of Original Sin, thereby making her sinless, perfect, and immaculate from all forms of evil. In Islam she is regarded as the virgin mother of the prophet Jesus. She is described in the Qur'an, in the Sura Maryam (Arabic: سورة مريم‎).

The New Testament begins its account of Mary's life with the Annunciation, the appearance to her of the angel Gabriel heralding her divine selection to be mother of Jesus. However, early non-biblical writings state that she was the daughter of Joachim and Saint Anne. The Bible records Mary's role in key events of the life of Jesus from his virgin birth to his crucifixion. Other apocryphal writings tell of her subsequent death and bodily assumption into heaven.

A number of important doctrines concerning Mary are held by Christian churches. Primary among these is that, as mother of Jesus, she became Theotokos, literally, the "God-bearer", or "Mother of God". This doctrine was confirmed by the First Council of Ephesus in 431. Christians of the major ancient traditions including the Catholic Church and the Eastern Orthodox Church believe that Mary lived a sinless life, offer prayers to God through Mary and venerate her as intercessor and mother of the church. Most Protestants, however, do not follow these devotions.
