My only surprise at the news that 1300 parishoners at a Catholic Church were exposed to Hepatitis A is that this kind of thing isn’t reported more often. Sharing the same cup of wine among hundreds of communicants probably infects thousands every Sunday, but since it’s just with colds or the flu, it escapes media attention.
This is another case where behavior that’s been accepted for decades from a church wouldn’t be tolerated for a moment if attempted by a private institution. Imagine, for instance, if a grocery store offered samples of grape juice from the same cup. The same people who happily eat the body and drink the blood on Sunday would be calling the health department or complaining to store management.
