Mary, the mother of Jesus in Christianity, is known by many different titles (Blessed Mother, Virgin Mary, Mother of God, Our Lady, Holy Virgin, Madonna), epithets (Star of the Sea, Queen of Heaven, Cause of Our Joy), invocations (Panagia, Mother of Mercy, God-bearer Theotokos), and several names associated with places (Our Lady of Loreto, Our Lady of Fátima).
All of these descriptives refer to the same woman named Mary, the mother of Jesus Christ (in the New Testament). They are used differently by Catholics, Eastern Orthodox, Oriental Orthodox, and some Anglicans. (Note: Mary Magdalene, Mary of Clopas, and Mary Salome are different women.)
