I knew it would happen. There are already two tickets to Papal Events on ebay. One ticket to the Mass in Washington and one ticket to the Mass in New York. People are bidding also. If you come across these DO NOT BID! They won't get into the stadium. Someone will get your money and you will be out of luck. The tickets all have bar codes that will bring up your name, address, and date of birth on a computer when scanned. If your photo ID and tickets information doesn't match, you don't get into the Mass.
To those selling or thinking about selling your tickets, or thinking about buying one, remember that the person who sells or buys these tickets commits the objective sin of simony. Simony is the sale of sacraments or sacramentals.
