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.

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.

The most Blessed Virgin Mary, in the first instant of her conception, by a singular grace and privilege granted by almighty God, in view of the merits of Jesus Christ, the savior of the human race, was preserved free from all stain of original sin.

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.

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.

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

The Roman Pontiffs have always...held that all those rites should be preserved which deviate neither from accuracy in matters of faith, nor from what is fitting.
