It may be, Venerable Brethren, that some may think We have dwelt too long on this exposition of the doctrines of the Modernists. But it was necessary, both in order to refute their customary charge that We do not understand their ideas, and to show that their system does not consist in scattered and unconnected theories but in a perfectly organised body, all the parts of which are solidly joined so that it is not possible to admit one without admitting all. For this reason, too, We have had to give this exposition a somewhat didactic form and not to shrink from employing certain uncouth terms in use among the Modernists. And now, can anybody who takes a survey of the whole system be surprised that We should define it as the synthesis of all heresies? Were one to attempt the task of collecting together all the errors that have been broached against the faith and to concentrate the sap and substance of them all into one, he could not better succeed than the Modernists have done. Nay, they have done more than this, for, as we have already intimated, their system means the destruction not of the Catholic religion alone but of all religion. With good reason do the rationalists applaud them, for the most sincere and the frankest among the rationalists warmly welcome the modernists as their most valuable allies.
For let us return for a moment, Venerable Brethren, to that most disastrous doctrine of agnosticism. By it every avenue that leads the intellect to God is barred, but the Modernists would seek to open others available for sentiment and action. Vain efforts! For, after all, what is sentiment but the reaction of the soul on the action of the intelligence or the senses. Take away the intelligence, and man, already inclined to follow the senses, becomes their slave. Vain, too, from another point of view, for all these fantasias on the religious sentiment will never be able to destroy common sense, and common sense tells us that emotion and everything that leads the heart captive proves a hindrance instead of a help to the discovery of truth. We speak, of course, of truth in itself - as for that other purely subjective truth, the fruit of sentiment and action, if it serves its purpose for the jugglery of words, it is of no use to the man who wants to know above all things whether outside himself there is a God into whose hands he is one day to fall.
True, the Modernists do call in experience to eke out their system, but what does this experience add to sentiment? Absolutely nothing beyond a certain intensity and a proportionate deepening of the conviction of the reality of the object. But these two will never make sentiment into anything but sentiment, nor deprive it of its characteristic which is to cause deception when the intelligence is not there to guide it; on the contrary, they but confirm and aggravate this characteristic, for the more intense sentiment is the more it is sentimental. In matters of religious sentiment and religious experience, you know, Venerable Brethren, how necessary is prudence and how necessary, too, the science which directs prudence. You know it from your own dealings with sounds, and especially with souls in whom sentiment predominates; you know it also from your reading of ascetical books - books for which the Modernists have but little esteem, but which testify to a science and a solidity very different from theirs, and to a refinement and subtlety of observation of which the Modernists give no evidence. Is it not really folly, or at least sovereign imprudence, to trust oneself without control to Modernist experiences?
Let us for a moment put the question: if experiences have so much value in their eyes, why do they not attach equal weight to the experience that thousands upon thousands of Catholics have that the Modernists are on the wrong road? It is, perchance, that all experiences except those felt by the Modernists are false and deceptive? The vast majority of mankind holds and always will hold firmly that sentiment and experience alone, when not enlightened and guided by reason, do not lead to the knowledge of God. What remains, then, but the annihilation of all religion, - atheism?
Certainly it is not the doctrine of symbolism that will save us from this. For if all the intellectual elements, as they call them, of religion are pure symbols, will not the very name of God or of divine personality be also a symbol, and if this be admitted will not the personality of God become a matter of doubt and the way opened to Pantheism? And to Pantheism that other doctrine of the divine immanence leads directly. For does it, We ask, leave God distinct from man or not? If yes, in what does it differ from Catholic doctrine, and why reject external revelation? If no, we are at once in Pantheism. Now the doctrine of immanence in the Modernist acceptation holds and professes that every phenomenon of conscience proceeds from man as man. The rigorous conclusion from this is the identity of man with God, which means Pantheism. The same conclusion follows from the distinction Modernists make between science and faith. The object of science they say is the reality of the knowable; the object of faith, on the contrary, is the reality of the unknowable. Now what makes the unknowable unknowable is its disproportion with the intelligible - a disproportion which nothing whatever, even in the doctrine of the Modernist, can suppress. Hence the unknowable remains and will eternally remain unknowable to the believer as well as to the man of science.
Therefore if any religion at all is possible it can only be the religion of an unknowable reality. And why this religion might not be that universal soul of the universe, of which a rationalist speaks, is something We do see. Certainly this suffices to show superabundantly by how many roads Modernism leads to the annihilation of all religion. The first step in this direction was taken by Protestantism; the second is made by Modernism; the next will plunge headlong into atheism.
