For centuries, the Roman Catholic Church relied mostly on taxes and donations to finance operations. But during World War II, Pope Pius created The Institute for the Works of Religion. Commonly known as the Vatican Bank, it now holds billions of dollars in assets. For decades, the Bank has been plagued by a series of scandals, including bribery and money laundering. And the author of a new book says the Bank collaborated with the Nazis and tried to hide that fact for years. Pope Francis has enacted a series of reforms to end the scandals and increase transparency. Diane and guests discuss the history of the Vatican Bank and the current pope’s efforts to make lasting changes.
