Chrysostom: " But that you should not say to me, that to find an instance of another’s sin is not to excuse our own—indeed where the thing done and not the doer of it is accused, we excuse the thing done.
Chrysostom said, "Don't tell me that finding fault in someone else's wrongdoing doesn't justify our own wrongdoings. If the act itself is being criticized, rather than the person who committed it, then we can be excused for having done that very same action.
