This brings to mind a wonderful video game, Assassin's Creed 2, where you scale the wall of the 15th century Vatican City and make your way to the Sistine Chapel, where you proceed to leap from the ceiling and attack the corrupt and evil pope in the final act. What an epic experience, that game is a work of art by the way. And what a lovely plot line, belonging to a group who seek to expose all religion as an illusion used as a tool to rule mankind in a quite literal conspiracy of ancient and global proportions. Fiction of course, but outstanding.
Back on topic, it's a real shame the meaning of this is going to be distorted by some as publicity for the two atheist authors.
