Priests can fiddle the accounts, and the greedy ones probably do.
Do they? Is this a significant phenomenon, compared to some other line of work? Got any statistics on that? The accountants at the chanceries of the bishops these priests answer to, who audit their books, would be very interested if you have special insight on this subject.
Your comments sound like a casual, lazy slime from someone who doesn't know the field he's describing, but feels safe doing so. I know you're most likely just being sloppy, but would please put up or shut up? And preferably apologize?
