From the Treasury of Daily Prayer:

Whenever the New Testament Gospels name the women who were with Jesus, St. Mary Magdalene is listed first (John 19:25 is the only exception), perhaps because she was the first one to see the risen Savior alive. Luke 8:2 reports that Jesus had cured her of being possessed by seven demons. Through the centuries, she has often been identified with the repentant “woman of the city” who anointed Jesus’ feet as He sat at the table in the Pharisee’s home (Luke 7:36-50). But there is no biblical basis for this identification of her with a penitent prostitute. Nor is she to be identified with Mary, the sister of Martha, in Bethany. According to the Gospels, Mary Magdalene saw Jesus die; she witnessed His burial; and, most important, she was the first to see Him alive again after His resurrection (John 20:11-18). It is for good reason that Bernard of Clairvaux calls her “the apostle to the apostles.”
