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 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.

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

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

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

Now you know well that the most deadly foes of the Catholic religion have always waged a fierce war, but without success, against this Chair [of St. Peter]; they are by no means ignorant of the fact that religion itself can never totter and fall while this Chair remains intact, the Chair which rests on the rock which the proud gates of hell cannot overthrow and in which there is the whole and perfect solidity of the Christian religion.

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.
