The foundation of all our confidence is found in the Blessed Virgin Mary. God has committed to her the treasury of all good things, in order that everyone may know that through her are obtained every hope, every grace, and all salvation. For this is His will: That we obtain everything through Mary.

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.

If a future Pope teaches anything contrary to the Catholic Faith, do not follow him.

[Dr. Constain James] refuted so well the aberrations of Darwinism.... [A system] which is repugnant at once to history, to the tradition of all people, to exact science, to observed facts, and even to reason itself, would seem to need no refutation. But the corruption of this age, the machinations of the perverse, the danger of the simple, demand that such fancies, altogether absurd though they are, should - since they borrow the mask of science - be refuted by true science.

Neither the true faith nor eternal salvation is to be found outside the Holy Catholic Church.

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!
