a luna fan! are you sure luna's infp? doesn't she speak in a rather directive manner? and she's very Fe one-on-one.
IMO Jesus is unable to be typed, but I don't think he is fictional either
Evanna Lynch, the actress who plays Luna, has a very light, airy quality to her that seems INFP to me. That, and the INFJs I have known IRL seem more in tune with societal norms (although they are still quirky in their own ways), while the INFPs are more like Luna in that they are more oblivious and/or care even less.
I would not say I am 100% sure that Luna is INFP, because the only one who could tell me that would be Luna herself She's INFx though, no doubt about that.
I'm reading Anna Karenina right now, and although I'm not far along, the character the book is named after seems very INFJ-ish to me. She's secretive, good with people, and prone to experience inexplicable omens and insights. That may end up changing as the story goes on, though; if it does or you have any plot details to discuss, please be careful to mark your spoilers so I can avoid them.

EDIT: Actually, it's even more clear when watching interviews. There's a lovely moment in this one where Cate's Ne leaves ISFP Brad Pitt kinda goin' "huh?"
I think her demeanor is consistent with an INFJ who's feeling buoyant and playful. She reminds me a lot of myself when I'm in a really good mood, and I don't see the kind of external poise in NFPs that she shows in that interview. NFPs tend to have more of an internal poise; it's as though they can let anything flow over and through them and drift along very smoothly, while on the inside, they're in full control, making all the judgment calls that most people never notice.
