21 And whereas they deny that they themselves are bound by the Roman laws, and repute those laws as criminal, yet now they think that they ought to be avenged, as it were, by the Roman laws. Where were those laws when they themselves set fire to the roofs of the sacred basilicas? If Julian did not avenge the Church because he was an apostate, will you, O Emperor, avenge the injury done to the Synagogue, because you are a Christian?
