Bock is known for his work concerning The Da Vinci Code by Dan Brown. In a response to the theological implications of the novel, Bock wrote Breaking the Da Vinci Code, his best-selling work to date. The book challenges the historicity of various extra-biblical ideas expressed in The Da Vinci Code, most notably the supposed marriage of Jesus to Mary Magdalene. He also has written many pieces for beliefnet.com and ChristianityToday.com. Bock also wrote The Missing Gospels, which argues for the existence and legitimate primacy of early Christian proto-orthodoxy over non-canonical gospels and beliefs.
On May 17, 2006, immediately before the film The Da Vinci Code opened, Bock appeared on the TV show Nightline, talking about his book and about the movie. Bock has debated agnostic bible scholar Bart Ehrman on whether the gospels have been forged.
