To thee, St Louis, lily of virginity, brilliant star, and vessel of sanctity, we have recourse in prayer. Diffuse by thy intercession heavenly graces over the Catholic nations with which thou art united by ties of affinity, and over which thou hast been appointed protector by God. Implore of God and the Immaculate Virgin that the faith of our ancestors may again be revived among Christian people, that charity may burn, and virtuous living flourish. Obtain true peace for princes and their subjects, the triumph of our holy Mother the Church over her enemies, complete liberty for the Vicar of Christ on earth in his sacred government of souls, and for all of us who implore thine aid, eternal happiness in Heaven. Amen.
