Libertas §22

²² All this, however, We have explained more fully elsewhere. We now only wish to add the remark that liberty of so false a nature is greatly hurtful to the true liberty of both rulers and their subjects. Religion, of its essence, is wonderfully helpful to the State. For, since it derives the prime origin of all power directly from God Himself, with grave authority it charges rulers to be mindful of their duty, to govern without injustice or severity, to rule their people kindly and with almost paternal charity; it admonishes subjects to be obedient to lawful authority, as to the ministers of God; and it binds them to their rulers, not merely by obedience, but by reverence and affection, forbidding all seditious and venturesome enterprises calculated to disturb public order and tranquillity, and cause greater restrictions to be put upon the liberty of the people. We need not mention how greatly religion conduces to pure morals, and pure morals to liberty. Reason shows, and history confirms the fact, that the higher the morality of States; the greater are the liberty and wealth and power which they enjoy.
