I forget which denomination it was, but I remember hearing a story about some American Protestants who went to visit and help out at a sister church of the same denomination in Europe. The Americans were totally shocked by the fact that the the Europeans, who professed to be Christians, were drinking all the time. The Europeans, on the other hand, couldn't get over the fact that the American kids dressed wore shorts. My point is that drinking is very much a cultural thing, moreso than a religious issue.
My husband was raised in what I would consider a fundamentalist Baptist household. He's been Orthodox for a while, but I've mentioned on this board before that sometimes an issue will pop up and all of a sudden, he's channeling Pat Robertson. This happened the other day regarding alcohol (which my husband drinks every single day, btw).
We were talking about my hometown, which very well may be the Worst Place in America. Last week, the (now) former mayor was indicted by the federal government for conspiracy to distribute cocaine, arson (he burned down someone's house because they wouldn't sell him the land it was on), tons of political crimes, and paying a 14-year-old girl to have an extended sexual relationship with him (he's 73). Half the city and county government is in prison for horrible things like that, and the county is well-known as a haven for drug producers and all types of criminals. So anyway, we're talking about this place, and about the fact that the former mayor and others were elders in the biggest church in town, and my husband says, "You have to wonder if they really believe they are Christians. I mean, they say they are Christians, but then they go and do stuff like drink and listen to rap music." I swear, it's a good thing he was driving, because I would have wrecked right then. With all the truly horrible things going on there, drinking and listening to rap were the two things that stuck out in his mind as un-Christian behavior. The mind boggles. But my point is that while drinking can be sinful (as can eating), the idea that it is some kind of arch-sin is kind of bizarre, and almost exclusively the realm of American Protestants (and I think Mormons).
