When you read the Bible you’ll find scores of texts that refer to alcohol. These references include commands, narrative, and wisdom. What you’ll find is that there are no commands to abstain from alcohol completely. There are commands to specific people (i.e. Samson) to abstain from alcohol but a proper hermeneutic will tell you that it doesn’t apply to you in the same sense. What you will find are commands to abstain from drunkeness (i.e. 1 Cor.6.10). When reading historical narratives the author will not always explicitly condemn the sin, you’re supposed to already understand what is good and bad. When you read through narratives and prophecies you’ll find consequences and condemnation for drunkeness, but not alcohol.
As for those who condemn alcohol all together, I think they’ve either got a bad hermeneutic or are fallaciously post hoc (after the fact, therefore because of the fact). After the drinking, you are drunk, therefore, drinking is bad. Now, this may be true, but when you factor in the hermeneutics and will, it may just be bad reasoning. I find drunkeness to be condemned but not alcohol, why? I think this brings up the post hoc issue. It isn’t alcohol that’s the problem, it’s your motivation to get drunk and lack of self-control. Why is it that you’re desiring to get drunk? You’ll find many proverbs dealing with why you shouldn’t get drunk (remember, proverbs aren’t commands). To complement the point, Ephesians 5.18 commands us to be filled with the Spirit and not be drunk with wine (notice the important contrast, it’s more than just a command to abstain from drunkeness).
What about my Christian liberty and freedom? We mustn’t be stumbling block to others, but we can’t extrapolate this to the extreme. I find some people to say, “You can drink, but don’t be a stumbling block and don’t drink in public.” That’s a bit extreme, soon enough you’ll be in your closet hiding from the world sipping on your chardonnay, but please don’t do that, you’re getting signs of being an alcoholic then… The point is to do what you can, within reason, to not lead anyone to temptation. If you’re having a recovering alcoholic over for dinner, don’t offer him a glass of wine. If you make an agreement to abstain from, well anything, that’s another issue and you should follow it.
If you can’t tell, I don’t have an objection to alcohol. I don’t agree with getting drunk, I think that prohibition is clear in the Bible. Christians have the freedom to drink in moderation. If you’re convicted and you’re conscience doesn’t permit you to drink for whatever reason, great. Follow through on your convictions, but don’t apply your convictions to other people, that is legalism.
