Diuturnum §26

²⁶ The Church of Christ, indeed, cannot be an object of suspicion to rulers, nor of hatred to the people; for it urges rulers to follow justice, and in nothing to decline from their duty; while at the same time it strengthens and in many ways supports their authority. All things that are of a civil nature the Church acknowledges and declares to be under the power and authority of the ruler; and in things whereof for different reasons the decision belongs both to the sacred and to the civil power, the Church wishes that there should be harmony between the two so that injurious contests may be avoided. As to what regards the people, the Church has been established for the salvation of all men and has ever loved them as a mother. For it is the Church which by the exercise of her charity has given gentleness to the minds of men, kindness to their manners, and justice to their laws. Never opposed to honest liberty, the Church has always detested a tyrant's rule. This custom which the Church has ever had of deserving well of mankind is notably expressed by St. Augustine when he says that "the Church teaches kings to study the welfare of their people, and people to submit to their kings, showing what is due to all: and that to all is due charity and to no one injustice."(32)
