2 Now this, Our paternal affection, remaining, as it does, unaltered, We cannot disguise that tidings which have recently come to Us from Ireland have deeply pained and grieved Us. We have learned that an untoward excitement has suddenly arisen because the Sacred Congregation, whose office it is to vindicate the authority of the Church against those who resist it, has decreed that those methods of warfare known as Boycotting and the Plan of Campaign, which had begun to be employed by many, may not lawfully be used. And what is more to be deplored, there are not a few who have come forward and summoned the people to excited meetings, where inconsiderate and dangerous opinions are set in circulation, the authority of the Decree not being spared. For not only is the real scope of this Decree grievously perverted by means of forced interpretations, but, furthermore, it is even denied that obedience is due to the Decree, as if it were not the true and proper office of the Church to decide what is right and what is wrong in human actions.
