The seventh and final Potter book, entitled 'Harry Potter and the Deathly Hallows', has sold 11.5 million copies in its first 10 days in the U.S, according to Scholastic.
The global publishing, education and media company has stated 350 million copies to date have been sold worldwide. Currently, the Harry Potter series claimed eight spots on the USA Today bestseller list, including a deluxe edition of the Harry Potter book.
The enormous popularity of the eight-book series has been capitalised by Christians who are using it as an evangelism tool to spread the message of the Gospel.
Connie Neal, a fellow author, told the Associated Baptist Press that she led a guy to Christ using Harry Potter. Neal started reading the book as a 'concerned parent' and became so mesmerised by it that she wrote 3 books countering claims that Harry Potter 'glorify' paganism.
In a review of the latest Harry Potter, Jeffrey Weiss from The Dallas Morning News wrote the book was 'distinctly Christian' even though there was no mentioned of "God, gods, heaven or hell and There's no prayer."
He said that J.K. Rowling, the author of the Harry Potter series, finally revealed plainly 'that her Christian faith undergirds her factional creation;' by explicitly stating that Harry Potter's parents were Christian where on the inscription of the tomb it reads: "The last enemy that shall be destroyed is death.''
The Church of England has released a guidebook on using the series to teach 9-13 year olds children about the concept of sacrifice and mercy, through drawing parallels from both the book and the real world, reported the Guardian newspaper.
However, other Christians strongly disagree with the beneficial impact of the book. James Dobson, the president of the Focus of the Family, has strongly spoken out against it, saying that it has a negative effect on young impressionable mind given it mentioned witchcraft.
