For, as to miracles, they oftentimes, while they profited another, have injured him who had the power, by lifting him up to pride and vainglory, or haply in some other way: but in our works there is no place for any such suspicion, but they profit both such as follow them, and many others.
These then let us perform with much diligence. For if you change from inhumanity to almsgiving, you have stretched forth the hand that was withered. If you withdraw from theatres and go to the church, you have cured the lame foot. If you draw back your eyes from an harlot, and from beauty not your own, you have opened them when they were blind. If instead of satanical songs, you have learned spiritual psalms, being dumb, you have spoken.
These are the greatest miracles, these the wonderful signs.
