Although the readers (the Dan Brown ones) are used to it
, the topics related to Christianity and Bible are not referred to directly. But then, Dan Brown is used to using religion into fiction, and The Lost Symbol is no different. Masons are a secret organization; and the enormous amount of information about them provided by the author in the book comes as a pleasant surprise. This doesn't mean there are no flaws in the book, and the way the ancient academic knowledge is used in the book shows a confidence from the author which is not explained fully. The Lost Symbol is still a fun read, due to extremely efficient mix of the ancient knowledge with the modern sci-fi.
