According to the Gospel of John, Mary of Clopas was one of the women present at the crucifixion of Jesus. She brought some of the supplies for his burial. Sources suggest that she was the wife of Clopas, who may have been a brother of Saint Joseph.
Along with Mary Magdalene and Mary, mother of James, Mary of Clopas is known as one of the Three Marys at the tomb of Jesus. Her relics are said to be in France at the Church of the Saintes Maries de la Mer.
Mary of Clopas is explicitly mentioned only in John 19:25, where she is with the women present at the crucifixion of Jesus. The Gospels of Mark and Matthew each include similar passages. This has led some scholars to identify Mary of Clopas as the mother of James and Joseph. She was with the women who went to the tomb to anoint the body of Jesus with spices.
Jerome (347-420), writing Against Helvidius in defense of the perpetual virginity of the mother of Jesus, said the brothers of Jesus were children of Mary of Clopas, the sister of the mother of Jesus, making them first cousins of Jesus. Jerome also identified James, with the Apostle James, son of Alphaeus, and thus supposed that Mary of Clopas was married to Alphaeus.
