"Gianluigi Nuzzi, the author of the 2009 book that precipitated the string of events from Caloia's exit to the motu proprio, expressed the feelings of many Vaticanologists: "A few years ago, an anti-money-laundering law in the Vatican and the Holy See would have been unthinkable. They used to say, 'We're a sovereign state; these are our affairs.' The important thing is that they created an anti-money-laundering law and an authority to enforce it. Without that, the Vatican Bank will remain an offshore bank."
