About the Enciclopedia Cattolica

The Enciclopedia Cattolica is a comprehensive Italian Catholic encyclopedia originally published in 12 volumes between 1948 and 1954 by the Ente per l'Enciclopedia Cattolica e per il Libro Cattolico in Vatican City.

Publication Details

The editorial work was carried out by Casa Editrice G. C. Sansoni of Florence. The encyclopedia received the Nihil obstat on 9 October 1948 from Dominicus Mondrone and Marius Colpo S.J., Delegated Reviewers, and the Imprimatur from Archbishop Aloysius Traglia, Vicesgerens of the Vicariate of Rome.

Dedication

The encyclopedia was dedicated to Pope Pius XII, described as "Angelic Pastor, Teacher of the Christian People, Inspirer of Every Noble Enterprise," in the 50th year of his priesthood and the 10th year of his elevation to the Chair of Peter.

Presentation by Cardinal Pizzardo

Catholic culture has intensified its progress in recent decades, as can be seen from the manifold activity of institutions and individuals in the most varied disciplines. Such progress is all the more significant in times like ours, in which various and contrasting trends of ideas have produced a widespread skepticism that profoundly affects contemporary life, exposing it, more than ever, to fearful disarray.

In such an atmosphere, full of unanswered doubts and states of mind erected into systems, the evident, imperative, and noble task of Catholic scholars is to clarify and evaluate the formulations and solutions of problems concerning the highest values of the spirit, in the light of that perennial revealed truth which forms the sacred and fruitful deposit of the Catholic Church. Such a task possesses all the hallmarks of that apostolate which, if always proper to Catholic life, today appears absolutely indispensable.

The present Catholic Encyclopedia intends to be a conscious and eloquent expression of this apostolate, at the end of a tragic conflict of arms and blood that has so anguished the peoples, and which is none other than the natural and sinisterly demonstrative fruit of a more tremendous conflict, originating from ideologies in contrast with the Christian Idea.

In the Catholic field there has been no lack of encyclopedias presenting a panoramic exposition of Catholic positions, both in culture and in practice. A first and important example was the extensive Dizionario di erudizione storico-ecclesiastica by Gaetano Moroni (103 volumes, Venice 1840-61 and 1878-79). Among other more notable works of the same nature, more modern examples can be cited: for France, the Dictionnaire pratique des connaissances religieuses by J. Bricout (6 volumes, Paris 1925-28) and Catholicisme hier aujourd'hui demain by J. Jacquemet (Paris 1947); for Germany, the Kirchenlexikon by J. Hergenröther - F. Kaulen (13 volumes, Freiburg i. Br. 1882-1903) and the Lexikon für Theologie und Kirche by M. Buchberger (10 volumes, 1930-38); for America, The Catholic Encyclopedia (16 volumes, New York 1907-14 and 1 Supplement volume, 1922), all praiseworthy and meritorious works in many respects.

However, the need was felt not only among Catholics, especially Italians, but generally throughout the intellectual world, for an instrument of culture and information, updated to the latest advances in various disciplines.

Thus arose the idea of publishing a new Catholic Encyclopedia, to whose initial implementation valiant scholars dedicated themselves, to whom others then joined to form a committee of authoritative representatives of Catholic thought and doctrine, gathered near the See of Peter.

Well understanding all its importance, I encouraged the provident initiative of the scholars, to whom I expressed all my praise, comforted by the blessing of the gloriously reigning Supreme Pontiff, strenuous defender of Christian civilization and culture.

Character of the Encyclopedia

The Catholic Encyclopedia is written in Italian and the majority of collaborators are Italian; but both its significance and its reality transcend the borders of a nation. It intends to be and is Catholic, first of all for its sure orthodoxy; as well as because it is published in the Rome of the Apostles and Martyrs and in the more immediate light of the Chair of Peter in which resides the supreme and infallible magisterium.

Illuminated and comforted by this indefectible light, the ecclesiastical universities of Rome, in which worthy representatives of every nationality lavish treasures of doctrine, have constituted the heart and soul of the work, committing themselves to a vigilant and continuous effort so that the Catholic Encyclopedia may become, with eventual future updates, an ever valid instrument of Catholic culture.

The proper character of a Catholic Encyclopedia is all here: it does not at all intend to restrict itself to constituting a broad and reliable repertory of information, agnostically content with the pure exposition of the latest data of the sciences; on the contrary, it holds to its Catholicity of inspiration and content, nor does it believe thereby to diminish its own ideal and scientific value; indeed, such value it considers confirmed and enlarged by the broad and secure horizons of faith, which, providing organicity and guarantee of doctrine, transforms erudition into culture, and culture into ferment of life.

— G. Card. Pizzardo, Vatican City, 2 March 1949
