Pascendi Dominici Gregis: On the Doctrines of the Modernists
25 But it is not enough for the Modernist school that the State should be separated from the Church. For as faith is to be subordinated to science, as far as phenomenal elements are concerned, so too in temporal matters the Church must be subject to the State. They do not say this openly as yet - but they will say it when they wish to be logical on this head. For given the principle that in temporal matters the State possesses absolute mastery, it will follow that when the believer, not fully satisfied with his merely internal acts of religion, proceeds to external acts, such for instance as the administration or reception of the sacraments, these will fall under the control of the State. What will then become of ecclesiastical authority, which can only be exercised by external acts? Obviously it will be completely under the dominion of the State. It is this inevitable consequence which impels many among liberal Protestants to reject all external worship, nay, all external religious community, and makes them advocate what they call, individual religion. If the Modernists have not yet reached this point, they do ask the Church in the meanwhile to be good enough to follow spontaneously where they lead her and adapt herself to the civil forms in vogue. Such are their ideas about disciplinary authority. But far more advanced and far more pernicious are their teachings on doctrinal and dogmatic authority. This is their conception of the magisterium of the Church: No religious society, they say, can be a real unit unless the religious conscience of its members be one, and one also the formula which they adopt. But his double unity requires a kind of common mind whose office is to find and determine the formula that corresponds best with the common conscience, and it must have moreover an authority sufficient to enable it to impose on the community the formula which has been decided upon. From the combination and, as it were fusion of these two elements, the common mind which draws up the formula and the authority which imposes it, arises, according to the Modernists, the notion of the ecclesiastical magisterium . And as this magisterium springs, in its last analysis, from the individual consciences and possesses its mandate of public utility for their benefit, it follows that the ecclesiastical magisterium must be subordinate to them, and should therefore take democratic forms. To prevent individual consciences from revealing freely and openly the impulses they feel, to hinder criticism from impelling dogmas towards their necessary evolutions - this is not a legitimate use but an abuse of a power given for the public utility. So too a due method and measure must be observed in the exercise of authority. To condemn and prescribe a work without the knowledge of the author, without hearing his explanations, without discussion, assuredly savours of tyranny. And thus, here again a way must be found to save the full rights of authority on the one hand and of liberty on the other. In the meanwhile the proper course for the Catholic will be to proclaim publicly his profound respect for authority - and continue to follow his own bent. Their general directions for the Church may be put in this way: Since the end of the Church is entirely spiritual, the religious authority should strip itself of all that external pomp which adorns it in the eyes of the public. And here they forget that while religion is essentially for the soul, it is not exclusively for the soul, and that the honour paid to authority is reflected back on Jesus Christ who instituted it.
