Pope Pius IX

Atheism in legislation, indifference in matters of religion, and the pernicious maxims which go under the name of Liberal Catholicism are the true causes of the destruction of states; they have been the ruin of France. Believe me, the evil I denounce is more terrible than the Revolution, more terrible even than The Commune. I have always condemned Liberal Catholicism, and I will condemn it again forty times over if it be necessary.
