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.

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.

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 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.

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!

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

Liberal Catholics are the worst enemies of the Church.
