Liberalism Is the Heresiarchy of the Times

Liberalism is not an ordinary heresy. It has been very rightly called heresiarchy [the major heresy] by Fr. Chesnel (The Rights of God and Modern Ideas).

It is Satan's own personal heresy, since it consists of the creature usurping for his own profit the independence and sovereignty that belong only to God from all eternity, and in the order of time to Our Lord Jesus Christ. We see by this how modern Liberalism differs from all that preceded it in terms of revolt and sin.

It is sin itself, the final end and the highest degree. Liberalism calls for "the man of sin;" it prepares the way for the Antichrist.

The liberal seduction has blinded almost all intelligences; the last notions of true Christianity are vanishing as they fade away in minds. What a transformation in ideas, morals and beliefs from the regal jurists of the 14^th and 15^th centuries to the present day, passing through Luther, Voltaire and Jean-Jacques Rousseau, and Lamennais, the great seducer of Catholics! They are the sons of the same idea, the agents of the same seduction. Their successive appearances mark the stages of the revolutionary movement.

The last to arrive, Lamennais, is not the least dangerous or least disastrous. He is the father and the head of the school that is both Catholic and revolutionary, the school of pacification, adaptation, union and, finally, fusion between Christianity and the Revolution.
