Cardinal Pie: Keep the Deposit

Adapted [and translated via Google Chrome] from here.

Hear this maxim, O you reckless Christians, who so quickly adopt the ideas and language of your time, you who speak of reconciling the faith, of reconciling the Church, with the modern spirit, with the new law. And you who accept with so much confidence the most hazardous aims of what our century so proudly calls science, see how far you are from the program drawn by the great apostle: Devitans profana vocum novitates, and opposition falsi nominis scientiae.

But, take care. With these temerities, we do not take long to be driven further than we think. By placing themselves on this slope of profane novelties, by obeying these currents of so-called science, many have fallen from faith: Quam quidam promittentes, circa fidem exciderunt. Have not you often been saddened, frightened, my venerable Brothers, by hearing the language of certain men, who still believe themselves to be children of the Church, who convince themselves that they have not come out of their mother's bosom? have not abandoned the belief of their baptism, what am I saying? of men who perform even many of the Christian practices, and who frequent the holy table?

Hear their words, collect their questions, their doubts, their affirmations, their hesitations, their denials, and answer if these slaves of the novelty, if these dupes of the opposing philosophy and the separated science, at the time when they believe themselves still standing, are not already on the ground, in a word, circa fidem exciderunt? Do you still believe they are children, do you believe them members of the Church, those who, wrapped in words as vague as those of modern aspirations, forces of progress and civilization, highly affirm the existence of a "secular conscience," a secular and political conscience, opposed to "the conscience of the Church," against which they claim the right and the duty to react to correct and correct it? Ah! how many passengers, how many pilots who, still believing themselves in the boat, and playing with the profane novelties and lying science of their time, have already sunk and are in the abyss : quam quidam promittentes, circa fidem exciderunt
