4 In the preparation for your celebrations, the power of the Catholic religion as an excellent promoter of public safety and as the source or support of good things among the peoples shines forth. Certainly, as your wiser historians state, the Hungarian nation would not have held their occupied areas either very long or very prosperously unless the Gospel had led it, freed from the yoke of superstition, to accept these well-known principles: to respect natural law, to do harm to no one, to be merciful, to pursue peace, to be subject to princes as to God, and to practice brotherhood at home and abroad.
