17 It is very important for these words to sink deep into the mind of every priest. If someone owns things that are rightfully his, let him be careful not to hang on to them greedily. Instead he should remember that the prescriptions of the Code of Canon Law dealing with church benefices make it clear that he has a serious obligation "to use superfluous income for the poor or for pious causes."(25) May God grant that no one of Us ever lets that terrible sentence that the parish priest of Ars once used in rebuking his flock fall on him: "There are many people keeping their money hidden away while many others are dying of hunger."(26)
