It is an argument based upon a previously arrived at conclusion rather than one based upon examining the facts or paying attention to what was written before arriving at the conclusion.
John 2:1-10 1On the third day a wedding took place at Cana in Galilee. Jesus' mother was there, 2and Jesus and his disciples had also been invited to the wedding. 3When the wine was gone, Jesus' mother said to him, "They have no more wine." 4"Woman, why do you involve me?" Jesus replied. "My hour has not yet come." 5His mother said to the servants, "Do whatever he tells you." 6Nearby stood six stone water jars, the kind used by the Jews for ceremonial washing, each holding from twenty to thirty gallons. 7Jesus said to the servants, "Fill the jars with
water"; so they filled them to the brim. 8Then he told them, "Now draw some out and take it
to the master of the banquet." They did so, 9and the master of the banquet tasted the water that had been turned into wine. He did not realize where it had come from, though the servants who had drawn the water knew. Then he called the bridegroom aside 10and said, "Everyone brings out the choice wine first and then the cheaper
wine after the guests have had too much to drink; but you have saved the best till now."
Anyone that reads the Bible without some preconceived idea that wine is not wine would never come to the conclusion that when wine is mentioned in the Bible it actually refers to something other than wine. Jesus was accused of hanging around with drunkards not with people that drank too much grape juice. Did the apostles, after being accused of being drunk, say they only ever drank a thing called wine that was in reality grape juice so they could not ever have been drunk? No, they said it was too early to be drinking so being drunk at that hour was not likely.
Funny how the servant was amazed at the quality of the wine Jesus provided since he was used to the serving of the bad wine after people got drunk so they wouldn't be any the wiser about the quality. I wonder how those people could have gotten drunk on grape juice. Why , if they had not become drunk from drinking too much wine, would they be oblivious to the fact they were being given a beverage of poorer quality? How much grape juice would one need to consume before not noticing the next glass was not as good as the previous one?
