My first discussion with a Jew started in High School, when he said that Christians were wrong when they had more than one God. I first responded that we have only one God, but there are three persons in dialogue with one another who are God. He said, "Well, the Bible says there's only one God." I pointed out the creation of man in Genesis 2, and the discussion of Babylon in Genesis 11, both places in which God apeaks of himself as plural. He didn't believe me, so we went to the chapel and looked it up. Then he said, "Well, Judaism isn't really based on the Bible, it's based on the Talmud." I asked what that was, and he described a difficult multi-volume work, and I quit debating, since I wasn't really interested in any bible other than the one I carried.
There are a number of books on the subject I've read as well, but I won't go into Michael Hoffman's books here. I'm just surprised that after a nation-defining event, at least the old testament should be thoroughly understood: but they generally are uninterested in the bible, and a little resentful that I think it's important and that it says things they don't expect.
