"For what advantage is it, that the world enjoys profound peace, if thou art at war with thyself? This then is the peace we should keep. If we have it, nothing from without will be able to harm us. And to this end the public peace contributes no little: whence it is said, ‘That we may lead a quiet and peaceable life.’ But if any one is disturbed when there is quiet, he is a miserable creature. Seest thou that He speaks of this peace which I call the third (inner, ed.) kind? Therefore when he has said, ‘that we may lead a quiet and peaceable life,’ he does not stop there, but adds ‘in all godliness and honesty.’ But we cannot live in godliness and honesty, unless that peace be established. For when curious reasonings disturb our faith, what peace is there? or when spirits of uncleanness, what peace is there?"
