The Da Vinci Code, a popular suspense novel by Dan Brown, generated criticism and controversy after its publication in 2003. Many of the complaints centered on the book's speculations and misrepresentations of core aspects of Christianity and the history of the Catholic Church. Additional criticisms were directed toward the book's inaccurate descriptions of European art, history, architecture, and geography.

Charges of copyright infringement were also leveled by the novelist Lewis Perdue and by the authors of the 1982 book The Holy Blood and the Holy Grail, which puts forward the hypothesis that the historical Jesus married Mary Magdalene, and that their children or their descendants emigrated to what is now southern France, and married into families that became the Merovingian dynasty, whose claim to the throne of France is championed today by the Priory of Sion. In 2006, a court ruled in Brown's favor, stating that while he did reference the book in parts of his novel, he did not substantially copy it. A similar suit was filed in 2007 by author Jack Dunn, who accused Brown of plagiarizing his 1997 novel The Vatican Boys.

Criticism of The Da Vinci Code

Fact or fiction

Brown prefaces his novel with a page titled "Fact" asserting that certain elements in the novel are true in reality, and a page at his website repeats these ideas and others. In the early publicity for the novel, Dan Brown made repeated assertions that, while the novel is a work of fiction, the historical information in it is all accurate and well-researched. For example:

These claims in the book and by the author, combined with the presentation of religious ideas that some Christians regard as offensive, led to a great deal of controversy and debate, which found its way into political discourse in the media. In May 2006, The Independent reported that Ruth Kelly, a senior British Government Minister, had been scrutinized about her membership in Opus Dei during her early years as an Education Secretary.

Mary Magdalene

The novel asserts that Mary Magdalene was of the Tribe of Benjamin, but historians dispute this claim, and there is no mention of this in the Bible or in other ancient sources. According to Sandra Miesel and Carl E. Olson, writing in their 2004 book, The Da Vinci Hoax, state the fact that Magdala was located in northern Israel, whereas the tribe of Benjamin resided in the south, weighs against it.

In Chapter 58 it is suggested that the marriage of Jesus and Mary Magdalene created a "potent political union with the potential of making a legitimate claim to the throne." Olson and Meisel not only state that this assertion is without any historical basis, but question why Solomon's kingship would have any purpose or meaning today that would motivate a large-scale conspiracy. The authors also question why if Jesus were merely a "mortal prophet", as the novel suggests, a royal goddess would have any interest in him. Olson and Meisel quote Chicago archbishop Francis Cardinal George, who remarked, "Jesus isn't God but Mary Magdalene is a goddess? I mean, what does that mean? If he's not God, why is he married to a goddess?" Olson and Meisel also argued that having Davidic blood in Jesus' time would not have been unique, since all of his stepfather Joseph's relatives, which included twenty generations of kings of Judah, had it as well. The authors also state that the Benjamites were not considered "rightful" heirs to the throne, and that the New Testament does not mention Mary Magdalene's tribal affiliation, and that she was likely not from the tribe of Benjamin, and that her connection with that tribe is traced to the 1982 book Holy Blood, Holy Grail, which does not substantiate the idea.

Characters in the book also claim that Mary Magdalene was labeled a prostitute by the Church. While Catholic tradition in the past, in contrast to other Christian traditions, defended these imputations, these claims are now rejected by the majority of biblical scholars, Catholic and non-Catholic alike, according to Carol Ann Morrow of AmericanCatholic.org. Also, Pope Gregory I's teaching about Mary Magdalene, though popular throughout much of the Church's history, was never formally integrated into Catholic dogma; nor was he speaking ex cathedra at the time, so his speech is not seen as infallible. Whatever weight is given to this tradition, however, there is no evidence that it was used to defame Mary, who was and still is considered a saint to whose honor churches have been built. She is also respected as a witness to Christ's resurrection as written in the Gospels.
