Liberal Catholics are the worst enemies of the Church.

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.

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.

If anyone says that it is possible that at some time, given the advancement of knowledge, a sense may be assigned to the dogmas propounded by the Church which is different from that which the Church has understood and understands: let him be anathema.

Socialism, Communism, clandestine societies, Bible societies... pests of this sort must be destroyed by all means.

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.
