In America, calls for the books to be banned from schools have led to legal challenges often on the grounds that witchcraft is a government-recognised religion and that to allow the books to be held in public schools violates the separation of church and state. The Orthodox church of Bulgaria and a diocese of the Orthodox Church of Greece have also campaigned against the series. The books have been banned from all schools in the United Arab Emirates. Religious responses to "Harry Potter" have not all been negative. "At least as much as they've been attacked from a theological point of view," notes Rowling, "books have been lauded and taken into pulpit, and most interesting and satisfying for me, it's been by several different faiths."
