“How in the heck could anyone recognize it? Its been in storage for two decades.”
You think people didn’t see it? I saw such things in storage in two different chanceries. If I saw that stuff, then so would other people. Also, there is documentation for many of these sacred vessels. And, many of them produced after 1900, have inscriptions. This had none.
“Its not like it was put on the back of milk cartons for twenty years.”
Priests would still know about it and have seen it - and they would be the ones able to identify it. Think, man, think.
How do you know that?
Are you serious? How many people have access to storage at the Basilica of the National Shrine of the Immaculate Conception?
Is a visit to it on the itinerary of the daily tours?
