I. He laments the recent violence in Palestine

The information you provide, brother, about the riotous actions of the false monks is grave and deeply lamentable. These disturbances are the direct result of the war that the wicked Eutyches, through the madness of his deceivers, is waging against the preaching of the Gospel and the Apostles -- though it will end in his own destruction and that of his followers. This ruin is delayed only by the long-suffering of God, so that it may become clear how thoroughly the enemies of the cross of Christ are enslaved to the devil. For heretical wickedness, breaking through its ancient veil of pretense, can no longer restrain itself within the limits of hypocrisy. It has poured forth all its long-concealed poison, attacking the disciples of truth not only with the pen but also with acts of violence, in an effort to wrest consent from unlearned simplicity or from faith paralyzed by fear.

But the children of light must not be so intimidated by the children of darkness that they acquiesce, as sane men, in the ideas of madmen, or show deference to men of this kind. If these agitators would rather perish than recover their senses, measures must be taken to prevent their impunity from causing wider harm. Prolonged toleration of them will only lead to the destruction of many more.

II. The ringleaders must be removed to a distance

I am well aware of the love and consideration due to our sons who have embraced the monastic life. But true monks serve Christ in humility and obedience, not in sedition and violence. Those who stir up tumult under the guise of defending the faith are enemies of the faith they pretend to champion.

We therefore urge that the ringleaders of these disturbances be removed from the vicinity where they can do further harm. Their influence must be broken, and the faithful must be reassured that the Catholic truth, confirmed by the Council and by the authority of the Apostolic See, stands firm against all assaults. Let the monks who are genuinely devoted to their calling be distinguished from those who have perverted the monastic life into an instrument of faction.

Attend to this matter with your customary vigilance, brother, and keep us informed of developments.
