In 2005, Cardinal Tarcisio Bertone publicly responded to the claims of the novel, which he called 'a castle of lies.' A series of reactionary books bent on disproving the novel's theories emerged, and documentaries exploring the controversies it brings out were aired on networks from ABC to the History Channel. In 2004, it was banned from Lebanon when Catholic leaders protested against its content. Religious leaders, Christian scholars, historians, and media figures reacted strongly to Brown's novel. When asked in an interview what he would change if he were writing the book as nonfiction rather than fiction, for example, Brown replied he would change nothing. Was Jesus married to Mary Magdalene? Did early Christian leaders attempt to suppress her significance? Did Constantine the Great and the Council of Nicaea establish the divinity of Jesus Christ in 325 a.d.? Was Leonardo da Vinci one of the 'keepers of the secret of the Holy Grail,' as Leigh Teabing, the historian scholar, declares? Did he encode his art with symbols that suggested a Christian history far different from the one with which we are familiar? Though fictional characters raise these questions, Brown, in interviews about his novel, generated much debate by defending the possibility that Christian history has been carefully and artificially constructed.

While the plot moves along rapidly, the narrative and dialogue slow down briefly at times to explore weighty issues and consider controversial questions. It is a fast-paced thriller involving Harvard professor of religious symbology Robert Langdon, who must solve a murder mystery before he is arrested for the murder himself. The Da Vinci Code became one of the first notable international literary events of the twenty-first century as soon as it was published in early 2003.
