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

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.

In fact, there is only one true and holy religion, founded and instituted by Christ Our Lord. Mother and Nurse of the virtues, Destroyer of vice, Liberator of souls, Guide to true happiness, she is called Catholic, Apostolic, and Roman.

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.

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.

Liberal Catholics are the worst enemies of the Church.
