Q. Is it permissible for a Christian to drink alcoholic beverages?
As I understand it, this would be a matter of individual conviction. In Romans 14, Paul discusses various things about which Christians of good will can have honest differences of conviction. At the beginning of the discussion, he mentions eating meat (probably in context meaning food offered to idols) and observing the Sabbath. The principles Paul teaches are that each person “should be fully convinced in their own mind” and that everyone should “make every effort to do what leads to peace and to mutual edification.” That means specifically not doing anything that would lead fellow believers to violate their own consciences and fall into sin. At the end of the discussion, Paul says by way of summary, “It is better not to eat meat or drink wine or to do anything else that will cause your brother or sister to fall.” This suggests that he considers whether or not to drink wine also to be a matter of individual conviction, like Sabbath observance and eating meat.
The Bible does stress that drunkenness is a sin. So any Christian who feels the liberty to drink alcoholic beverages such as wine must do so in moderation. This is a second qualification on the freedom, in addition to the mandate not to cause a fellow believer to sin.
I should also note that in that same discussion in Romans, Paul says, “Let us stop passing judgment on one another.” On matters of individual conviction, we answer to God, not to other people’s opinions of what we should or should not do. Paul says this even more strongly in Colossians: “Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. These are a shadow of the things that were to come; the reality, however, is found in Christ.” Ideally we can recognize that choices that rest on individual conviction are minor matters, and we can concentrate on major matters, which have to do with how we can all grow up into the image of Christ.
