Today is the feast of St. Louis IX, king of France. Louis’s insistence on taking the cross [in December 1244] and journeying to the Holy Land was an outgrowth of his deep faith and love for Christ. He yearned to see Jerusalem under Christian control once more. His desire was so great that he was prepared to risk his personal and royal fortunes on the expedition. He was sovereign of the wealthiest region in all Christendom and the king of the most populous Christian country. There was much to lose by going on Crusade, but King St. Louis IX knew that the eternal reward greatly outweighed the temporal risk.
