“No, it cannot be permitted that laymen who profess to be Catholic should go so far as openly to arrogate to themselves in the columns of a newspaper, the right to denounce, and to find fault, with the greatest license and according to their own good pleasure, with every sort of person, not excepting bishops, and think that with the single exception of matters of faith they are allowed to entertain any opinion which may please them and exercise the right to judge everyone after their own fashion.
But since We are here dealing with the lapse of a newspaper, it is absolutely necessary for Us once more to enjoin upon the editors of Catholic journals to respect as sacred laws the teaching and the ordinances mentioned above and never to deviate from them. Moreover, let them be well persuaded and let this be engraved in their minds, that if they dare to violate these prescriptions and abandon themselves to their personal appreciations, whether in prejudging questions which the Holy See has not yet pronounced on, or in wounding the authority of the Bishops by arrogating to themselves an authority which can never be theirs, let them be convinced that it is all in vain for them to pretend to keep the honor of the name of Catholic and to serve the interests of the very holy and very noble cause which they have undertaken to defend and to render glorious.”
