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.

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

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.

Liberal Catholics are the worst enemies of the Church.

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!

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 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.
