John Chrysostom
See how Festus speaks about him: he not only presents him as innocent, but also defends him. What does he say? See how he accuses the Jews and justifies Paul. Look at their frenzy: they cried out that he ought to die. From this it is clear that Paul rightly transferred the case to Caesar. If the Jews raged even when nothing blameworthy could be said against him, then he had to appeal to him.
