This is also a wake up call to those who usher or are Eucharistic ministers to be watchful of folks who do not immediately consume the host upon reception.
I usher at Our Lady’s Shrine in DC and one of our duties is to make sure that the host is immediately consumed by the recipient. I’ve had 2 occasions where I had to ask the recipient to do this. One young person put it in his shirt pocket, another person held it is their hand until they got back to their seat.
There are all kinds of nutcases out there. What their purpose is unknown. Some are trying to get souvenirs. Personally, I think they should all be horsewhipped or shocked with a cattle prod. It is the ultimate in disrespect and irreverence. I’m not too keen on the folks who like to dip the host in the wine either (it is not an oreo cookie ! ) Just my opinion.
