Pascendi Dominici Gregis §6

⁶ We begin, then, with the philosopher. Modernists place the foundation of religious philosophy in that doctrine which is usually called Agnosticism . According to this teaching human reason is confined entirely within the field of phenomena , that is to say, to things that are perceptible to the senses, and in the manner in which they are perceptible; it has no right and no power to transgress these limits. Hence it is incapable of lifting itself up to God, and of recognising His existence, even by means of visible things. From this it is inferred that God can never be the direct object of science, and that, as regards history, He must not be considered as an historical subject. Given these premises, all will readily perceive what becomes of Natural Theology, of the motives of credibility, of external revelation . The Modernists simply make away with them altogether; they include them in Intellectualism , which they call a ridiculous and long ago defunct system. Nor does the fact that the Church has formally condemned these portentous errors exercise the slightest restraint upon them. Yet the Vatican Council has defined, "If anyone says that the one true God, our Creator and Lord, cannot be known with certainty by the natural light of human reason by means of the things that are made, let him be anathema" ( De Revel ., can. I); and also: "If anyone says that it is not possible or not expedient that man be taught, through the medium of divine revelation, about God and the worship to be paid Him, let him be anathema" ( Ibid. , can. 2); and finally, "If anyone says that divine revelation cannot be made credible by external signs, and that therefore men should be drawn to the faith only by their personal internal experience or by private inspiration, let him be anathema" ( De Fide , can. 3). But how the Modernists make the transition from Agnosticism , which is a state of pure nescience, to scientific and historic Atheism , which is a doctrine of positive denial; and consequently, by what legitimate process of reasoning, starting from ignorance as to whether God has in fact intervened in the history of the human race or not, they proceed, in their explanation of this history, to ignore God altogether, as if He really had not intervened, let him answer who can. Yet it is a fixed and established principle among them that both science and history must be atheistic: and within their boundaries there is room for nothing but phenomena ; God and all that is divine are utterly excluded. We shall soon see clearly what, according to this most absurd teaching, must be held touching the most sacred Person of Christ, what concerning the mysteries of His life and death, and of His Resurrection and Ascension into heaven.
