St. Louis was born to be the king of France, but his mother, Blanche, raised him to be a devoted servant of Christ as well as his country. Perhaps because he lived in a palace, surrounded by comforts, King Louis IX made it a habit to wear a hair shirt (which made him itch) under his fancy clothes so he would never forget the sufferings of the poor and oppressed. He fed more than 100 poor people every day from the royal table, and twice, he went to war to protect Christians in other countries.
For many, many years Christians have done different things that made them just a little bit uncomfortable so that they have a constant reminder to pray or to serve others. Try it today with three strands of itchy wool yarn (representing the Father, the Son and the Holy Spirit) knotted around your wrist.
