Supposedly, at least according to the book, the joining of male and female created the divine---so if you had sex, you were God. They were, uh, worshiping.. . On another note, most of the "fact" in the DaVinci Code isn't fact at all. Ex. on the History Channel, they showed that the Priory of Sion, you know, the secret group that the whole novel based on, never actually existed. All the documents that "proved" it were a fabrication of a Frenchman named Planchard, who was convicted of falsifying the documents by a French court.
