I have heard many teetotalists say that the water supply in Jesus's day was bad and so people drank wine. But then again I was reading a RC Sproul commentary on the book of John and he said this is not true as the water was fine. He also argued that John the Baptist was expected to be a teetotalist but when Christ came he would symbolize the heavenly celebration of which he did in John 2. I do not have a bible dictionary on my phone so I am not sure who is right and who is wrong. RC Sproul makes good arguments and hence at his church they use wine in communion.
