Give me an army saying the Rosary and I will conquer the world.

Because God knows, searches and clearly understands the minds, hearts, thoughts, and nature of all, his supreme kindness and clemency do not permit anyone at all who is not guilty of deliberate sin to suffer eternal punishments.

The Church is built on the rock of Peter, and he who eats the Lamb outside this holy dwelling is reprobate .. .He who eats the Lamb outside this Apostolic See has no part with God!

I have always condemned Liberal Catholicism and I will condemn it again forty times over if it be necessary.

It is error to believe that Every man is free to embrace and profess that religion which, guided by the light of reason, he shall consider true.

Nothing can ever pass away from the words of Christ, nor can anything be changed in the doctrine which the Catholic Church received from Christ to guard, protect, and preach.

Socialism, Communism, clandestine societies, Bible societies... pests of this sort must be destroyed by all means.

The state (the U.S. Constitution) has not the right to leave every man free to profess and embrace whatever religion he may desire.

The civil liberty of every mode of worship, and full power given to all of openly and publicly manifesting their opinions and their ideas conduce more easily to corrupt the morals and minds of the people... The Roman Pontiff cannot and ought not to reconcile himself or agree with, progress, liberalism and modern civilization.

These enemies of divine revelation extol human progress to the skies, and with rash and sacrilegious daring would have it introduced into the Catholic religion as if this religion were not the work of God but of man, or some kind of philosophical discovery susceptible of perfection by human efforts.
