Corrected entry: In the Da VInci Code, Opus Dei is depicted as a clandestine society of sinister monks. In reality, Opus Dei is an organization made up of lay people who lead rather ordinary lives. It contains very few priests and no monks at all.

Correction: This is similar to the entries about the Priory of Sion, which have both been corrected. The book's interior logic is that these societies are in fact much older and secretive, and that the organizations you find today (and in real life) are just innocent-looking cover-ups for the real thing.
