It's one of the slogans on posters and in previews advertising the movie "The Da Vinci Code," which premieres nationwide Friday.

Some Fredericksburg-area churches have taken that message to the pulpit--planning sermons, Sunday school classes and other programs around Dan Brown's best-selling novel-turned-movie.

Stafford Crossing Community Church launched an eight-part series on "The Da Vinci Code" Sunday.

"Some people say, 'Why are you engaging fiction for eight weeks in a church service?'" said the Rev. Darryl Mosley, the church's senior pastor.

For Mosley, the answer is on the first page of "The Da Vinci Code," which reads, "Fact: All descriptions of artwork, architecture, documents and secret rituals in this novel are accurate."

The novel's premise is that Jesus Christ and Mary Magdalene were married and have a traceable line of descendants.

It also fosters the conspiracy theory that the Catholic Church has covered up their marriage.

In a 2003 interview with Charles Gibson of ABC's "Good Morning America," Brown said "The Da Vinci Code" wouldn't have been different if it was written as nonfiction.

Because Brown's premise questions the very foundation of Christianity, Mosley said he sees the movie's premiere as a catalyst for a dialogue about the faith and its history.

The church direct-mailed postcards and advertised its series in The Free Lance-Star.

"I'm not out to bash Dan Brown or 'The Da Vinci Code' itself," Mosley said. "I think he's done us a great favor because now we have to get answers to questions and verify the validity of our faith."

The church, which meets at Stafford High School off Mountain View Road, will hold sermons on "The Da Vinci Code" every Sunday through July 2 at 9:30 a.m.

The church posts MP3 audio files of sermons on its Web site, staffordcrossing.org.

Bethel Reformed Presbyterian Church in Fredericksburg also has devoted several weeks to discussing "The Da Vinci Code."

The church, which meets at the George Washington Executive Center on Princess Anne Street, has "Da Vinci" sermons this Sunday and May 28 at 11 a.m.

"Whether we go to the movie or not, or read the novel or not, it becomes part of a cultural dialogue," said the Rev. Stephen Doe, the church's pastor. "We have to be intelligent--we have to know what's being said and why things are being said."
