Breaking her silence on the much-debated question as to whether religious themes permeate her books, Rowling confirmed that they echoed her personal struggle with faith.
Speaking in America this week, she was open about the Christian allegories in her latest book Harry Potter and the Deathly Hallows.
The author said that she had always deflected questions on the issue in the past to avoid disclosing the direction in which the books were heading.
"To me, the religious parallels have always been obvious," Rowling said. "But I never wanted to talk too openly about it because I thought it might show people who just wanted the story where we were going."
At the end of her latest and final installment in the series, there are specific references to Christianity and themes of life after death and resurrection.

"They are very British books, so on a very practical note, Harry was going to find biblical quotations on tombstones," she said.
"But I think those two particular quotations he finds on the tombstones ...they sum up, they almost epitomise, the whole series."
However the author, who was brought up an Anglican and is now a member of the Church of Scotland, said she still wrestled with the concept of an afterlife.
"The truth is that, like Graham Greene, my faith is sometimes that my faith will return. It's something I struggle with a lot.
"On any given moment if you asked me if I believe in life after death, I think if you polled me regularly through the week, I think I would come down on the side of yes - that I do believe in life after death.
"But it's something I wrestle with a lot. It preoccupies me a lot, and I think that's very obvious within the books."
