There are certainly christian themes in HP, but it is fatally flawed as an actual allegory. Don’t get me wrong, I read every one and enjoyed them greatly, but there are as many problems as there are positive themes. While I don’t agree with those who place Potter on the same level as blatantly opposed to the faith (like the Gloden Compass series), neither does it rise to the level of christian allegory like Narnia or Lord of the Rings. Instead, I’d say the author may have intended to incorporate some christian themes, but she’s either not educated enough in christian theology to pull it off or she simply doesn’t believe in the totality of christian revelation.
