Amy Welborn writes in the December 12 2014 devotion for Living Faith:
At Mass in a cathedral in Mexico one Sunday, we were seated near a large reproduction of Our Lady of Guadalupe. All through Mass, people came and knelt in front of the image, prayed and then returned to the congregation. One man knelt facing the altar on the cool stone floor in front of the image. Shabbily dressed, he rose from his knees only once, then winced, sat down and rolled up his trouser leg to reveal a terribly swollen calf.
How about a free e-book about Mary?
My book Mary and the Christian Life, has been out of print for a couple of years, so I am offering a .pdf file of the text at no cost to anyone interested.
