Did Jesus change water into grape juice, or was it fermented wine?
The Greek word always used in the New Testament for fermented wine is “oinos.” It is this very word that is used in John 2. If the writer had wanted to refer to unfermented grape juice in John 2, then the Greek word “truz” for unfermented juice would have certainly been used. The Bible unequivocally condemns excessive wine drinking and drunkenness. It also recommends the moderate use of wine for medical purposes (1 Tim. 5:23). The question of whether Jesus changed water into wine or grape juice is a secondary issue that Christians can debate, but should not divide over.
