[SEP] Knowledge 2: Mary, mother of Jesus
The Protoevangelium of James, an extra-canonical book, has been the source of many Orthodox beliefs on Mary. The account of Mary's life presented includes her consecration as a virgin at the temple at age three. The High Priest Zachariah blessed Mary and informed her that God had magnified her name among many generations. Zachariah placed Mary on the third step of the altar, whereby God gave her grace. While in the temple, Mary was miraculously fed by an angel, until she was twelve years old. At that point an angel told Zachariah to betroth Mary to a widower in Israel, who would be indicated. This story provides the theme of many hymns for the Feast of Presentation of Mary, and icons of the feast depict the story. The Orthodox believe that Mary was instrumental in the growth of Christianity during the life of Jesus, and after his Crucifixion, and Orthodox Theologian Sergei Bulgakov wrote: "The Virgin Mary is the center, invisible, but real, of the Apostolic Church."
