 Because the father of lies is said to have so blinded the minds of certain [men], that they by [means of] false madness have obscured Our constitutions—not without much punishable temerity, unless they retract and lean themselves [once more] upon the truth, which these contain—of which one begins: "Ad conditorem canonum," the other indeed: "Quum inter non nullos," arranged diligently by previously held deliberation certainly as much with Our brother Cardinals of the Holy Roman Church, as with many Archbishops and Bishops, and other prelates of the [local] churches, and not a few masters of sacred theology, and professors of both [kinds] of law [i.e. civil and canon], and promulgated on the counsel of Our aforementioned brothers: lest by daring [and] pernicious deeds their pestiferous doctrine shake the souls of the simple so much, and prevail to lead them into the deviation of their own errors, on the counsel of certain brother [cardinals] We judge soberly to make provision concering this matter, as follows [below]. Moreover, they have used as much as word as writing to impunge the aforesaid constitutions, for the alleged reason, as is shown: They say that "That which the Roman Pontiffs had defined by [means of] the key of knowledge, in faith and morals, once for all, persists unchangeable to such an extent, that it is not lawful for a successor to call it again into doubt, nor to affirm the contrary," although concerning those things, which have been ordained by [means of] the key of power, they assert it to be otherwise.
