Those that have the fortune to visit the campus at Notre Dame are familiar with the Grotto of Our Lady of Lourdes. A replication of the grotto from the one in France, it as great a touchstone of Notre Dame as any other landmark on a campus that is full of them. On football weekends, one actually need to queue up for a kneeler from which to pray. Likewise, every day at 6:30, the Rosary is said there; rain or shine.
A recent visitor to campus was there and snapped a photo when walking past. Upon arriving home, they were amazed with what their camera had captured:
I'm not going to go into the long story as it is theirs to tell, and encourage you to read the blog post on the whole story.
There are about a dozen explanations for what may have transpired at that grotto on that cold, snowy day. Despite what is posited, I'd argue that our Holy Mother aligned things to remind us that she is with us as our constant advocate to her Son. She is our path to Him, and she will not fail us.
Hail, Mary, full of grace!
