I find it very hard to understand teetotal Christians.
My understanding of the term 'Christian' is someone who follows the teachings of Christ or seeks to be like Him in some way. And Jesus expressly told His disciples to drink wine to remeber Him. So why do so many Christians shun alcohol in all its forms? They are commanded to drink it!
Yes, I know there are several anti-drunkenness passages in the bible, but having a glass or two of wine is as far from drunkenness as driving sensibly is from breaking the speed limit.
