In case you didn't realize it, Catholics like Mary.** We do not pray to her like a god; we pray with her.*** The statue is a sign of respect and a reminder to us of the most excellent model of human virtue.
*Yes, the blue and gold reference is to notre dame -- our Lady, not the university. Blue and gold have traditionally been associated with Mary, and many Catholic schools use this color scheme to honor her. These include my elementary school as well as colleges like Notre Dame, Merrimack, St. Edward's University, College of St. Elizabeth, St. Joseph College (x2), St. Mary College (of Kansas San Antonio, and Maryland, but not the one in Indiana [which is blue and white also in honor of St. Mary]), College of St. Mary, St. Scholastica, St. Theresa, and St. Thomas (x2). If I had included all of the schools that use blue and white to honor Mary this list would go on for pages.****
**Sounds like a future post for Stuff Catholics Like?
***Sister Mary Martha has a post on this very topic.
***Yes, I did do a search for "Saint" on a sports uniform site to find most of the schools on this list.
