7. In the catholic church, during communion, wine is given to those who take the communion. Yet, Numbers 6:3 and Proverbs 23:31 affirm that we should not drink fermented wine, but fruit of the vine, a.k.a grape juice. I never liked that idea as a child, and the truth behind that act was revealed to me in becoming a born again Christian.If you look closely, all the biblical prohibitions are against getting drunk. Responsible drinking is certainly acceptible. Jesus and the Apostles all took wine to drink at the Last Supper (see here). He would not have made himself sacramentally present in wine if wine was prohibited. Jesus' first miracle was turning water to wine (John 2:1-11), and this after they had already drunk freely. Jesus drank wine, but perhaps you would call him a glutton and a drunkard, like the Pharisees did? (Lk 7:33-34). Finally, Paul told Timothy to "use a little wine for the sake of your stomach" (1 Tim 5:23).
As for the OT evidence, was Jacob wrong to drink the wine that Isaac brought to him (Gen 27:25)? Was Melchizedek wrong to offer it as a sacrifice to God (Gen 14:18)? Nehemiah commands the people to drink wine (Neh 8:10). The Psalmist says that God gives man plants so that he may make from them "wine to gladden the heart of man" (Psa 104:14-15). Wine is even used as a symbol of new life (Isa 25:6; Amos 9:14; Zech 10:7).
With all this, how can we say that we are never to drink it?
