Excerpt: On July 3rd, 1907, the Holy Father prepared a list of errors which, later, were grouped together under the name of Modernism, and condemned. On the 8th of September following he addressed to the Catholic world an Encyclical of incomparable fulness, vigour, and clearness, in which he sets forth his reasons for condemning Modernism. Thank God! these errors, which have so far invaded France and Italy, attract few followers in Belgium. You have been preserved by the vigilance of your pastors, by an impartial scientific spirit, and by the Christian submission that animates the representatives of higher learning in your country. Nevertheless, beloved brethren, I consider it a pastoral duty to bring to your knowledge this Pontifical Encyclical, which henceforth will be known in ecclesiastical history by its introductory Latin words: "Pascendi Domini gregis", or, more briefly, "Pascendi." Since the Holy Father addresses his letter to each Church in particular, that is, to the Bishops, priests, and Catholic laity, it is his intention that each one should individually profit by the Encyclical. The importance of this document, moreover, gives it an historic value: hence, those who are interested in our Mother, the Church, should know, at least in substance, its meaning. It is a well-known fact that scarcely had the Pope spoken, or rather before he had spoken, and from the moment that the telegraphic agents heralded his coming announcement, the unbelieving press began to misrepresent it, and the newspapers and reviews hostile to the Church in our country neither published the text nor the general tenour of the Encyclical with fulness or frankness. But with an eagerness and a harmony of opinion that altogether explain their attitude, they quibbled over the word Modernism in the endeavour to convince their confiding readers that the Pope condemns modern thought, which in their ambiguous language signifies modern science and its methods. This offensive and false impression of the Pope and his faithful followers has perhaps been shared by some amongst you, hence it is our earnest wish to remove this impression by explaining Modernism, and, in so doing, enlighten you as to the reasons that led to its condemnation by the Supreme Authority of the Church. WHAT IS THE FUNDAMENTAL IDEA OF MODERNISM? Modernism is not the modern expression of science, and consequently its condemnation is not the condemnation of science, of which we are so justly proud, nor the disapproval of its methods, which all Catholic scientists hold, and consider it an honour to teach and to practice. Modernism consists essentially in affirming that the religious soul must draw from itself, from nothing but itself, the object and motive of its faith. It rejects all revelation imposed upon the conscience, and thus, as a necessary consequence, becomes the negation of the doctrinal authority of the Church established by Jesus Christ, and it denies, moreover, to the divinely constituted hierarchy the right to govern Christian society. The better to understand the significance of this fundamental error, let us recall the teaching of the Catechism on the constitution and mission of the Catholic Church. Christ did not represent Himself to the world as the head of a philosophy and uncertain of His teaching! He did not leave a modifiable system of opinions to the discussion of His disciples. On the contrary, strong in His divine wisdom and sovereign power, He pronounced, and imposed upon men the revealed word that assures eternal salvation, and indicated to them the unique way to attain it. He promulgated for them a code of morals, giving them certain helps without which it is impossible to put these precepts into practice. Grace, and the Sacraments which confer it upon us, or restore it to us, when, having sinned, we again find it through repentance, form together these helps, this economy of salvation. He instituted a Church, and as He had only a few years to dwell
