32 And since in all cities, towns and villages, wherever the Christian religion thrives, there is a sanctuary, or at least an altar, in which the sacred image of the Blessed Virgin Mary is enshrined for the devotion of the Christian people, We desire, Venerable Brethren, that the faithful should throng thither in great numbers and should offer to our Most Sweet Mother not only private but also public supplications with one voice and with one mind.
