Pascendi Dominici Gregis §40

⁴⁰ To penetrate still deeper into Modernism and to find a suitable remedy for such a deep sore, it behoves Us, Venerable Brethren, to investigate the causes which have engendered it and which foster its growth. That the proximate and immediate cause consists in a perversion of the mind cannot be open to doubt. The remote causes seem to us to be reduced to two: curiosity and pride. Curiosity by itself, if not prudently regulated, suffices to explain all errors. Such is the opinion of Our Predecessor, Gregory XVI., who wrote: A lamentable spectacle is that presented by the aberrations of human reason when it yields to the spirit of novelty, when against the warning of the Apostle it seeks to know beyond what it is meant to know, and when relying too much on itself it thinks it can find the fruit outside the Church wherein truth is found without the slightest shadow of error (Ep. Encycl. Singulari nos , 7 Kal. Jul. 1834). But it is pride which exercises an incomparably greater sway over the soul to blind it and plunge it into error, and pride sits in Modernism as in its own house, finding sustenance everywhere in its doctrines and an occasion to flaunt itself in all its aspects. It is pride which fills Modernists with that confidence in themselves and leads them to hold themselves up as the rule for all, pride which puffs them up with that vainglory which allows them to regard themselves as the sole possessors of knowledge, and makes them say, inflated with presumption, We are not as the rest of men , and which, to make them really not as other men, leads them to embrace all kinds of the most absurd novelties; it is pride which rouses in them the spirit of disobedience and causes them to demand a compromise between authority and liberty; it is pride that makes of them the reformers of others, while they forget to reform themselves, and which begets their absolute want of respect for authority, not excepting the supreme authority. No, truly, there is no road which leads so directly and so quickly to Modernism as pride. When a Catholic laymen or a priest forgets that precept of the Christian life which obliges us to renounce ourselves if we would follow Jesus Christ and neglects to tear pride from his heart, ah! but he is a fully ripe subject for the errors of Modernism. Hence, Venerable Brethren, it will be your first duty to thwart such proud men, to employ them only in the lowest and obscurest offices; the higher they try to rise, the lower let them be placed, so that their lowly position may deprive them of the power of causing damage. Sound your young clerics, too, most carefully, by yourselves and by the directors of your seminaries, and when you find the spirit of pride among any of them reject them without compunction from the priesthood. Would to God that this had always been done with the proper vigilance and constancy.
