Several Christian writers have compared Rowling to the Inklings, a group that included C. S. Lewis, J. R. R. Tolkien, and Charles Williams, who explored Christian themes and morality in a fantasy context. Dave Kopel, citing John Granger's book, draws comparisons between Rowling's and Lewis's common usage of Christian symbols, such as lions, unicorns and stags. He compares the work to Lewis's Christian allegory: "In the climax of "Chamber of Secrets", Harry descends to a deep underworld, is confronted by two satanic minions (Voldemort and a giant serpent), is saved from certain death by his faith in Dumbledore (the bearded God the Father/Ancient of Days), rescues the virgin (Virginia Weasley), and ascends in triumph. It's "Pilgrim's Progress" for a new audience." (This quotation predates Rowling's revelation that Ginny Weasley's full name is Ginevra, not Virginia.)
