OK, thanks for the explanation. Is it your belief the wine that Jesus made was merely grape juice or fermented (though diluted)?
No. It was wine. The "it was grape juice" argument is an argument without any merit.
The Greek word translated "wine" is (οινος, οινουo, οινω) oinos, which was the common Greek word for normal wine, wine that was fermented/alcoholic.
The Greek word for the wine Jesus created is the same word for the wine the wedding feast ran out of.
The Greek word for the wine Jesus created is also the same word that is used in Ephesians 5:18, "...do not get drunk on wine..." Obviously, getting drunk from drinking wine requires the presence of alcohol.
Everything, from the context of a wedding feast, to the usage of oinos in 1st century Greek literature (in the New Testament and outside the New Testament), argues for the wine that Jesus created to be normal, ordinary wine, containing alcohol.
There is simply no solid historical, cultural, exegetical, contextual, or lexical reason to understand it to have been grape juice.
There are thirteen original Hebrew and Greek words for "wine" in our English Bible. How can we know which one means fermented wine? To find the answer, do not go to Aristotle or Pliny, but go to the Bible itself. By comparing its usage, the scriptural meaning of wine can be defined.
One of the original Hebrew words for wine is "yayin." This word is first used in Genesis 9:21 where Noah "drank of the wine and was drunken." This wine caused drunkenness! Was it just grape juice? Uh, no!
In Genesis 14:18 we read of Melchizedek – a type of Jesus Christ, or possibly even a Christophany – who "brought forth bread and wine: and he was the priest of the most high God." God Himself, in the person of Melchizedek, gave wine to Abraham. And again, the original Hebrew word was "yayin" which always means fermented wine. This same Hebrew word is used in Amos 9:14 speaking of the coming Millennium where the people will "plant vineyards, and drink the wine thereof." They will drink the same kind of wine that Noah drank and became drunk by overindulgence.
In the New Testament, one original Greek word for wine is oinos. Proof that it is alcoholic is given in the story of the good Samaritan. The Samaritan poured oil and wine on the man’s wounds (Luke 10:34), showing that the wine had enough alcoholic content to be used as an antiseptic. Would you pour grape juice on a wound?
The Greek word oinos is also used in John 2 where Jesus turned water into wine by a divine miracle. It is used in 1 Timothy 5:23, the command of Paul, "Drink no longer water, but use a little wine for thy stomach’s sake and thine often infirmities." This Greek word is also used in Ephesians 5:18, "And be not drunk with wine wherein is excess."
If God wanted to say "grape juice" He would have done so, just as He did in Acts 2:13 "Others mocking said, These men are full of new wine."
The words "new wine" are translated from the Greek word γλευκους (gleukos).
God is not an idiot. Had He wanted to say "grape juice" he would have said "grape juice" (γλευκους), but He didn't. He said (οινος) fermented, alcoholic wine, just like Paul cautioned about in Ephesians 5:18, "And be not drunk with wine . . . " (οινω).
