Episcopal Vigilance Over Publications
It is also the duty of the bishops to prevent writings infected with Modernism or favourable to it from being read when they have been published, and to hinder their publication when they have not. No book or paper or periodical of this kind must ever be permitted to seminarists or university students. The injury to them would be equal to that caused by immoral reading – nay, it would be greater for such writings poison Christian life at its very fount. The same decision is to be taken concerning the writings of some Catholics, who, though not badly disposed themselves but ill-instructed in theological studies and imbued with modern philosophy, strive to make this harmonize with the faith, and, as they say, to turn it to the account of the faith. The name and reputation of these authors cause them to be read without suspicion, and they are, therefore, all the more dangerous in preparing the way for Modernism.
To give you some more general directions, Venerable Brethren, in a matter of such moment, We bid you do everything in your power to drive out of your dioceses, even by solemn interdict, any pernicious books that may be in circulation there. The Holy See neglects no means to put down writings of this kind, but the number of them has now grown to such an extent that it is impossible to censure them all. Hence it happens that the medicine sometimes arrives too late, for the disease has taken root during the delay. We will, therefore, that the Bishops, putting aside all fear and the prudence of the flesh, despising the outcries of the wicked, gently by all means but constantly, do each his own share of this work, remembering the injunctions of Leo XIII. in the Apostolic Constitution Officiorum: Let the Ordinaries, acting in this also as Delegates of the Apostolic See, exert themselves to prescribe and to put out of reach of the faithful injurious books or other writings printed or circulated in their dioceses.
