A year ago, I had a sunday school class discussion and my teacher was asking all of us a question that "Are we allowed to drink wine regularly?" Well, as the question went around and people started to share their thoughts, the common and simple answer to that question was "No, but there are certain conditions."
In my opinion, I was thinking about how we always drink the transformed bread and wine as the blood and body of our Lord Jesus Christ every Sunday during the Holy Eucharist, so I guess it was okay.
St. Paul writes in 1 Timothy 5:23 that, "No longer drink only water, but use a little wine for your stomach's sake and your frequent infirmities." Also, in the parable of the Good Samaritan, that our Lord taught to his apostles and followers, it says that the Samaritan put wine on the beaten Jew's wounds, and then put olive oil. In other words, wine is good for the body as a whole, as well as for life.
