The real sin—perhaps it is the sin against the Holy Ghost for which there is no remission—is the sin of heresy, the sin of thinking for oneself. The saying has been heard before now, here in Spain, that to be a liberal—that is, a heretic—is worse than being an assassin, a thief, or an adulterer. The gravest sin is not to obey the Church, whose infallibility protects us from reason.

And why be scandalized by the infallibility of a man, of the Pope? What difference does it make whether it be a book that is infallible—the Bible, or a society of men—the Church, or a single man? Does it make any essential change in the rational difficulty? And since the infallibility of a book or of a society of men is not more rational than that of a single man, this supreme offence in the eyes of reason had to be posited.

It is the vital asserting itself, and in order to assert itself it creates, with the help of its enemy, the rational, a complete dogmatic structure, and this the Church defends against rationalism, against Protestantism, and against Modernism. The Church defends life. It stood up against Galileo, and it did right; for his discovery, in its inception and until it became assimilated to the general body of human knowledge, tended to shatter the anthropomorphic belief that the universe was created for man. It opposed Darwin, and it did right, for Darwinism tends to shatter our belief that man is an exceptional animal, created expressly to be eternalized. And lastly, Pius IX., the first Pontiff to be proclaimed infallible, declared that he was irreconcilable with the so-called modern civilization. And he did right.

Loisy, the Catholic ex-abbé, said: "I say simply this, that the Church and theology have not looked with favour upon the scientific movement, and that on certain decisive occasions, so far as it lay in their power, they have hindered it. I say, above all, that Catholic teaching has not associated itself with, or accommodated itself to, this movement. Theology has conducted itself, and conducts itself still, as if it were self-possessed of a science of nature and a science of history, together with that general philosophy of nature and history which results from a scientific knowledge of them. It might be supposed that the domain of theology and that of science, distinct in principle and even as defined by the Vatican Council, must not be distinct in practice. Everything proceeds almost as if theology had nothing to learn from modern science, natural or historical, and as if by itself it had the power and the right to exercise a direct and absolute control over all the activities of the human mind" (Autour d'un Petit Livre, 1903, p. 211).

And such must needs be, and such in fact is, the Church's attitude in its struggle with Modernism, of which Loisy was the learned and leading exponent.

The recent struggle against Kantian and fideist Modernism is a struggle for life. Is it indeed possible for life, life that seeks assurance of survival, to tolerate that a Loisy, a Catholic priest, should affirm that the resurrection of the Saviour is not a fact of the historical order, demonstrable and demonstrated by the testimony of history alone? Read, moreover, the exposition of the central dogma, that of the resurrection of Jesus, in E. Le Roy's excellent work, Dogme et Critique, and tell me if any solid ground is left for our hope to build on. Do not the Modernists see that the question at issue is not so much that of the immortal life of Christ, reduced, perhaps, to a life in the collective Christian consciousness, as that of a guarantee of our own personal resurrection of body as well as soul? This new psychological apologetic appeals to the moral miracle, and we, like the Jews, seek for a sign, something that can be taken hold of with all the powers of the soul and with all the senses of the body. And with the hands and the feet and the mouth, if it be possible.

But alas! we do not get it. Reason attacks, and faith, which does not feel itself secure without reason, has to come to terms with it. And hence come those tragic contradictions and lacerations of consciousness. We need security, certainty, signs, and they give us motiva credibilitatis—motives of credibility—upon which to establish the rationale obsequium, and although faith precedes reason (fides præcedit rationem), according to St. Augustine, this same learned doctor and bishop sought to travel by faith to understanding (per fidem ad intellectum), and to believe in order to understand (credo ut intelligam). How far is this from that superb expression of Tertullian—et sepultus resurrexit, certum est quia impossibile est!—"and he was buried and rose again; it is certain because it is impossible!" and his sublime credo quia absurdum!—the scandal of the rationalists. How far from the il faut s'abêtir of Pascal and from the "human reason loves the absurd" of our Donoso Cortés, which he must have learned from the great Joseph de Maistre!

And a first foundation-stone was sought in the authority of tradition and the revelation of the word of God, and the principle of unanimous consent was arrived at. Quod apud multos unum invenitur, non est erratum, sed traditum, said Tertullian; and Lamennais added, centuries later, that "certitude, the principle of life and intelligence ... is, if I may be allowed the expression, a social product."[21] But here, as in so many cases, the supreme formula was given by that great Catholic, whose Catholicism was of the popular and vital order, Count Joseph de Maistre, when he wrote: "I do not believe that it is possible to show a single opinion of universal utility that is not true."[22] Here you have the Catholic hall-mark—the deduction of the truth of a principle from its supreme goodness or utility. And what is there of greater, of more sovereign utility, than the immortality of the soul? "As all is uncertain, either we must believe all men or none," said Lactantius; but that great mystic and ascetic, Blessed Heinrich Seuse, the Dominican, implored the Eternal Wisdom for one word affirming that He was love, and when the answer came, "All creatures proclaim that I am love," Seuse replied, "Alas! Lord, that does not suffice for a yearning soul." Faith feels itself secure neither with universal consent, nor with tradition, nor with authority. It seeks the support of its enemy, reason.

And thus scholastic theology was devised, and with it its handmaiden—ancilla theologiæ—scholastic philosophy, and this handmaiden turned against her mistress. Scholasticism, a magnificent cathedral, in which all the problems of architectonic mechanism were resolved for future ages, but a cathedral constructed of unbaked bricks, gave place little by little to what is called natural theology and is merely Christianity depotentialized. The attempt was even made, where it was possible, to base dogmas upon reason, to show at least that if they were indeed super-rational they were not contra-rational, and they were reinforced with a philosophical foundation of Aristotelian-Neoplatonic thirteenth-century philosophy. And such is the Thomism recommended by Leo XIII. And now the question is not one of the enforcement of dogma but of its philosophical, medieval, and Thomist interpretation. It is not enough to believe that in receiving the consecrated Host we receive the body and blood of our Lord Jesus Christ; we must needs negotiate all those difficulties of transubstantiation and substance separated from accidents, and so break with the whole of the modern rational conception of substantiality.

But for this, implicit faith suffices—the faith of the coalheaver,[23] the faith of those who, like St. Teresa (Vida, cap. xxv. 2), do not wish to avail themselves of theology. "Do not ask me the reason of that, for I am ignorant; Holy Mother Church possesses doctors who will know how to answer you," as we were made to learn in the Catechism. It was for this, among other things, that the priesthood was instituted, that the teaching Church might be the depositary—"reservoir instead of river," as Phillips Brooks said—of theological secrets. "The work of the Nicene Creed," says Harnack (Dogmengeschichte, ii. 1, cap. vii. 3), "was a victory of the priesthood over the faith of the Christian people. The doctrine of the Logos had already become unintelligible to those who were not theologians. The setting up of the Niceno-Cappadocian formula as the fundamental confession of the Church made it perfectly impossible for the Catholic laity to get an inner comprehension of the Christian Faith, taking as their guide the form in which it was presented in the doctrine of the Church. The idea became more and more deeply implanted in men's minds that Christianity was the revelation of the unintelligible." And so, in truth, it is.
