23 Our forebears received them with deepest respect and venerated them with magnificent honors; and their descendants, emulating their piety, continue to cherish these images as highly sacred treasures. It is a delight for the mind to discover in this fact the approval and the favor of a mother wholly devoted to her children. For it seems to indicate that these images have been left in our midst as witness of the ages when the entire Christian family was held together by ties of absolute unity, and as so many precious pledges of our common inheritance. The very sight of them must needs invite souls, as though the Virgin herself were bidding them, to keep in devout remembrance those whom the Catholic Church calls with loving care back to the peace and the gladness which they formerly enjoyed, within her embrace.
