[jjdees]

I've wondered about this myself. It may be that the people who leave early aren't very well versed in their religion and think Mass is over when they've received communion. I've seen on a couple of occasions where a priest stops giving communion and walks over to a person who has walked off with the consecrated host and tells them to either consume it or return it. I asked a priest about this and he said he's read about devil worshippers using a consecrated host in their rituals. Sounds nutty but their are a lot of nuts in this world.
