Why is Mary Magdalene called “apostola apostolorum?”
“Apostola apostolorum” is Latin for “apostle to the apostles.” Mary Magdalene was first suggested to have fulfilled this role by Hippolytus in his commentary on the Song of Songs, because she received instructions at Jesus’ tomb to go tell the other disciples about the resurrection. This effectively made her the “apostle to the apostles.” The actual Latin phrase “apostola apostolorum” wasn’t used until the Middle Ages.
