I. He laments over the recent rioting in Palestine.
Leo, the pope, to Julian, the bishop.
The information which you give, brother, about the riotous doings of the false monks is serious and to no slight degree lamentable; for they are due to the war which the wicked Eutyches by the madness of 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: but this is delayed by the long-suffering of God, in order that it may appear how greatly the enemies of the cross of Christ are enslaved to the devil; because heretical depravity, breaking through its ancient veil of pretence can no longer restrain itself within the limits of its hypocrisy, and has poured forth all its long-concealed poison, raging against the disciples of the Truth not only with pen but also with deeds of violence, in order to wrest consent from unlearned simplicity or from panic-stricken faith. But the sons of light ought not to be so afraid of the sons of darkness, as being sane to acquiesce in the ideas of madmen or to think that any respect should be shown to men of this kind; for, if they would rather perish than recover their senses, provision must be made lest their escape from punishment should do wider harm, and long toleration of them should lead to the destruction of many.
