Since 1866, the Redemptorists have spread devotion to Mary under the icon and title of Mother of Perpetual Help. In that year the Redemptorists asked Pope Pius IX for permission to move the icon to their new church, Church of Sant’Alfonso in Rome, which was built on the location of the icon’s earlier home. The pope granted his permission, and told the Redemptorists to “make her known throughout the world.”
