Trust me, I know--my father is a Christian minister. As also mentioned earlier, though, it seems relatively clear that this isn't what she's thinking of. She thinks that Christianity and Greek polytheism were always contemporary, for example, and she thinks that there were no religions before Christianity. And since, as the religion is defined, Christianity relies on the actual physical manifestation of Jesus as the Christ, she's got all sorts of obvious questions she can't possibly answer.
Bingo. Although I wish someone brought up the whole pesky "˜Old Testament' problem; I would have paid to see her try to talk her way out of that one.
Regarding the roundness of the earth, only an idiot can possibly answer that question with "˜I don't know'. She is a person of means living in what is arguably the "˜first' country on earth at the end of 2007...I really can't believe she is for real; she is like a bad intellectual dream incarnate.
