We have heard from many sources of your piety’s efforts on behalf of true religion. It is therefore right that you should readily succour one who is calumniated for the same cause, and should refute the reviler’s lies. You, O godly Sir, know what I hold, and what I teach, and that no one has ever heard of my preaching two sons. Exert, I implore you, in this case too your divine energy, and stop the mouths of the evil speakers. In conflicts of this kind one must help not only one’s friends but even those who have caused us pain.
