We know Jesus drank wine. But did he get drunk?
But what about Christians getting drunk?
Is it a sin?
Is it not a sin?
What do you think?
This seems like the kind of thing that needs to be considered as something other than a matter of strict law. The trouble with trying to apply a strict law to this is that you end up with all sorts of issues with definitions, not least how to define what it means to be drunk.
Obviously in secular society there are certain things that don't go well with drinking - for most of us that means driving but could also mean flying, operating machinery, performing surgery etc. I'm not concerned with those here - if you're subject to specific laws that restrict drinking and define limits those apply.
In Eph 5:18 Paul says not to be drunk with wine because it leads to debauchery. And drinking too much certainly can lead to all sorts of behaviors that aren't appropriate for a Christian. That said, a lot of the time what is happening is that alcohol is merely lowering inhibitions and intoxicated people are more likely to do the things they wanted to do anyway, in which case perhaps the problem is as much about the underlying desires as the alcohol revealing them.
I don't see a problem with drinking alcohol in moderation. I would regard anything that permits someone to continue to do the things they need to do as falling within "moderation". So, for example, if I go out to my favorite brewpub with my wife and have a few beers, I see no problem with that. If my head feels a bit fuzzy I still see no problem, as long as I'm not driving home. If I start throwing up, or acting inappropriately towards the waitresses or other customers, there's a problem (this is where it's easier to argue someone is "drunk" rather than using other terms such as "fuzzy" or "tipsy" etc). If I have to be carried out to the car, there's a problem. If I'm at the brewpub every single night getting slightly fuzzy there's probably a case to be made about good stewardship of my body (based on the medical complications of sustained drinking) and my resources (based on there being better things to do with time and money than spending so much of it at the pub).
If others consider that even feeling a little fuzzy is inappropriate they are free to stop drinking before they reach that point, or indeed to not drink alcohol at all.
