The money-changers were men who cheated Jewish pilgrims out of money by forcing a terrible exchange rate upon them. Jewish pilgrims had currency from their own homelands, and they had to buy animals for sacrifice at the Temple, but they had to buy them with
Temple currency. So the moneychangers exchanged the pilgrim’s money for Temple money at a dishonest rate.
As for the bulletin, if there are companies that want to support the parish by purchasing advertising space in the bulletin (usually on the back cover), thereby letting parishioners know of services which may be of use to them, then may God keep them honest in their business and diligent in their work!
