How can anyone explain the popularity of the recent bestseller book series, Fifty Shades of Grey, and the subsequent movie? Though the books and movie portray a value system that would seem alien to any sincerely practicing Christian, polls show that the book has been read by as many as nine percent of American women who call themselves Christian. What is the appeal? Could it be, at least in part, that the very premise of the title—"shades of grey"—captures the worldly human desire to see right and wrong not as absolute, but as situational and relative?
