Did Obama define sin as "being out of alignment with my values."

I've seen some folks pass along the claim that Obama said the following:

Interviewer: Do you believe in sin?
OBAMA: Yes.
Interviewer: What is sin?
OBAMA: Being out of alignment with my values.

Now if Obama said such a thing, it's an amazing claim. And I could see him saying something like that. I just find it troubling that the source for the quote is a bit hard to pin down.

The quote is claimed to come from an interview he gave in 2004 to religion reporter Cathleen Falsani at the Chicago Sun-Times. The reporter has posted the "uncut" version of the interview on her blog. It's not clear that the quotation above made it into her original article or the book she later published - she does not claim it can be found in either. I wasn't able to find the article on the Sun-Times website, for instance. So that means it's only source I've been able verify is the personal website of the reporter.

Nonetheless, the above quote has already made it into Hot Air, and National Review Online blog not once, but twice. And now it's making its way around Catholic blogs.

I'd just feel better if someone had actually seen it in print before we spend too much time on it. Again, I'm not claiming Obama didn't say it, or wouldn't, I'm just saying it feels a bit too easy (considering what a short, easy line it is to pick apart).

But who knows, maybe it is.
