Last year, John Loftus and some colleagues published a book titled The End Of Christianity (Amherst, New York: Prometheus Books, 2011). The back cover and inside endorsements describe the book as "the sharpest set of intellectual criticisms [of Christianity] found under the cover of a single volume", "tremendously useful", "superb", and "exceedingly well-researched". One endorser claims, "This book should win the game: Christianity, it's strike three and you are out!" Another tells us, "No collection better demonstrates how taking Christianity seriously reveals its all-too-human origin." We're told that "Loftus and his friends annihilate the Christian Goliath".
Steve Hays and Jason Engwer have written an e-book in response, which you can read here, titled The End Of Infidelity, edited by Peter Pike.
Those who haven't read Loftus' book can find an overview of it here. Readers might want to read each chapter summary on the page linked before reading each of the chapter responses.
