He who has been stealing must steal no longer, but must work, doing something useful with his own hands, that he may have something to share with those in need. Ephesians 4:28
“Those who live in the midst of this life’s intense business appear to be forced, for the sake of food and necessary provisions, to buy and sell certain things and to seek unfair profit from business. It is difficult even for those who have been set free from the other passions–namely fornication, idolatry, adultery and murder–to escape being caught by this subtle vice.”
St. Jerome (347-420) in Epistle to the Ephesians 2.4.28.
