from an interview with JK Rowling in the Vancouver Sun, 26 Oct. 2000:
So far, despite all the odds, Potter and the forces of virtue and decency have triumphed. The moral significance seems clear.
''It does to you,'' says Rowling. ''And to me it's so blindingly obvious. But when this first became an issue I would take an enormous amount of time to explain what I thought was so obvious.
''Now I am starting to get impatient because I feel that you can lead a fool to a book but you can't make them think. And you can quote me, actually, because I'm just getting impatient about it.''
[...]
Harry, of course, is able to battle supernatural evil with supernatural forces of his own, and Rowling is quite clear that she doesn't personally believe in that kind of magic -- ''not at all.'' Is she a Christian?
''Yes, I am,'' she says. ''Which seems to offend the religious right far worse than if I said I thought there was no God. Every time I've been asked if I believe in God, I've said yes, because I do, but no one ever really has gone any more deeply into it than that, and I have to say that does suit me, because if I talk too freely about that I think the intelligent reader, whether 10 or 60, will be able to guess what's coming in the books.''
