The motto of St. Louis IX “Dieu le veult”, “God wills it”, was the rallying cry of the Crusaders. It bespeaks chivalry, courage, courtesy, enthusiasm ‑ all the virtues required by the ideal of Christian knighthood. Union in charity is again emphasized by the motto of the Sisters of St. Louis “Ut Sint Unum”, “that they may be one”, a prayer which was especially dear to the founder, Abbé Louis Bautain.
