Mel Gibson's new film, The Passion of The Christ, is driving up sales of Christian items like coffee mugs, bookmarks, jewelry, books and greeting cards. One popular jewelry item is the crucifixion nail pendant. Popular books include The Dolorous Passion of Our Lord Jesus Christ by Anne Catherine Emmerich and The Passion, a companion book to the movie. The film itself is doing great at the box office thanks partly to church groups that are going to see the film together.
