Gasp! BS you say, the Vatican surely would never be a party to any sort of chicanery?
I mean what next, peddling superstitious cures at Lourdes, selling off splinters from “the” cross, a pair of Jesus’s old pants on eBay?
Well duh! The real coin is in peddling magic, clearly. 
On my only visit to Rome, I was content to view the Vatican from St Peter’s square, did the usual tourist traps, drank cheap supermarket wine on a bench, next to the Tiber, looking at the impressive edifice of a papal castle, that a plaque claimed had never been conquered when Rome was sacked. Nice day, April in Rome is not too warm…the taxis on the way to the airport took us past some ancient gateways in to the city, tucked surreptitiously into hedgerows.
My only regret is taking, or at least not leaving, my ex wife there. 
We live and learn…
