It is important, therefore, for you to do what you can so that unbelievers may be converted to the faith, that converts may not turn away, that those who have turned away may return; moreover, that the perverse may be directed toward righteousness, the corrupted called back to the truth, and the corruptors refuted by invincible arguments so that they either correct their error, if that be possible, or, if it is not, that they lose their authority and the means of corrupting others. And you must not completely neglect the worst kind of fools; by this I mean heretics and schismatics, for these are the corrupted and the corruptors. Like dogs they tear apart; like foxes they deceive. You should make the greatest effort either to correct such men lest they perish, or restrain them lest they destroy others. Granted, time excuses you from dealing with the Jews: they have their boundary which cannot be passed. The full number of the Gentiles must come in first.
