Despite Mazarin's instructions, Louis XIV continued to correspond with Mazarin's niece Marie, with the tacit collusion of his mother. Mazarin immediately adopted a stricter tone: "God established Kings...for watching over the well-being, safety and peace of their subjects; and not to sacrifice this well-being and safety for their personal passions...you must remember your responsibilities to God for your actions and for your safety, and to the world for the support of your glory and your reputation." Mazarin also threatened to depart France with his family if the King did not agree to stop communicating with Marie. In response, Louis wrote a new letter to his mother, promising that henceforth he would forget Marie and concentrate exclusively on "the great occupation of King". ("Grand metier du Roi")
