During the Marian Congress which preceded the definition of the dogma of the Assumption last November, G. Gaetano di Sales, who leads a movement Pro Rogalitate Mariae, gave a paper on the meaning of the ‘Miraculous Medal’ and of the symbol of our Lady with a globe in her hand. He pointed out how specially indebted he was to this Marian devotion as he had been brought back to the faith by a special grace received in the Chapel of the Apparitions from which the devotion sprang. The following summary will convey the substance of the paper read in Rome.
