Thus spoke Pius VI in his marvelous Inscrutabile:
Consequently, you who are the salt of the earth, guardians and shepherds of the Lord’s flock, whose business it is to fight the battles of the Lord, arise and gird on your sword, which is the word of God, and expel this foul contagion from your lands. How long are we to ignore the common insult to faith and Church? Let the words of Bernard arouse us like a lament of the spouse of Christ: “Of old was it foretold and the time of fulfillment is now at hand: Behold, in peace is my sorrow most sorrowful. It was sorrowful first when the martyrs died; afterwards it was more sorrowful in the fight with the heretics and now it is most sorrowful in the conduct of the members of the household…. The Church is struck within and so in peace is my sorrow most sorrowful. But what peace? There is peace and there is no peace. There is peace from the pagans and peace from the heretics, but no peace from the children. At that time the voice will lament: Sons did I rear and exalt, but they despised me. They despised me and defiled me by a bad life, base gain, evil traffic, and business conducted in the dark.” Who can hear these tearful complaints of our most holy mother without feeling a strong urge to devote all his energy and effort to the Church, as he has promised? Therefore cast out the old leaven, remove the evil from your midst. Forcefully and carefully banish poisonous books from the eyes of your flock, and at once courageously set apart those who have been infected, to prevent them harming the rest.
