Nothing personal. Do note the material fact that you are the only person on this thread arguing that it is a sin to get drunk.
Popularity does not make one right or wrong, nor does lack of popularity.
As a point of respect, however, you have chosen your words much more carefully than I have, as to successfully remain above reproach. Well done.
The tongue is the rudder of the body. If one cannot control it, they cannot control other areas of life, and if one cannot control that then nor can they allow it under Christ's control.
I prefer to interpret this and other moral dilemmas from the perspective of personal relationship, where my decisions are the result of private conversations I have with God, rather than autonomously doing what I think some book is telling me to do. I see the Bible as a guide to help me better understand the context of my relationship with God, not as an instruction manual on how I ought to behave in the 21st century.
Without the Bible, your idea of God is no different than Islam's. It is the Bible we derive our theology from, it is the Bible that provides objective guidelines for what a relationship with God looks like, how one acts in that relationship, and what sort of behavior God wants from us. While automatically following the Bible without any intentionality or thought for what it says isn't best, nor is treating it as just another book helpful for a personal relationship with God.
The question of this thread is, "Is getting drunk a sin?"
We are therefore not dealing with moral or immoral, ethical or unethical, we are dealing by necessity with theology. Without the Bible to support that theology, it is nothing more than hollow opinion. It is not us who establish what is and is not sin, it is God, through the authors of the Bible. Anything not in the Bible is a matter of principle- does the Bible support the principle of the act or thought- and a matter of if one can personally handle it.
As I said, my stepfather is in the hospital right now. He's a recovered alcoholic who's drank for the sole reason of getting drunk and forgetting about the world. He got drunk enough times over enough years to be in the final stages of liver disease. He needs a new liver. If he doesn't get one in the next few months, he will die. Alcohol is a poison, and whether you go by medical information, psychological information, or biblical information, it is not healthy to constantly get drunk or to get drunk in general. Nor is it wise. From the Bible's perspective, it is a sin because one lacks self control that we are mandated to have in numerous places.
Jesus Himself said that we are His friends if we do what He commands (John 15), implying that we are not if we do not do what He commands, and He's commanded numerous things through numerous people.
You look at almost any story of someone getting drunk in the Bible and the result is always negative, as is any story of the Israelites turning away from God, as is any story about murder, as is any story about bearing false witness. That there are numerous instances in the OT against it and direct commands against the sort of lack of control being drunk produces speaks volumes about what the authors- who had a much more personal relationship with God than we have today- viewed as important for their relationship with God. That priests were not allowed to drink any wine also speaks to that.
Much.
