It is well-known that Charles Dickens wrote his novels to reform a variety of problems in his society. There is no exception in his last and unfinished novel, The Mystery of Edwin Drood. Here he criticizes the Anglican Church because he thought it was neglecting its duties toward its society as well as its congregation. Dickens believed many church leaders must play an import an role in their social changes, but they were satisfied just with their routines in serious mannerisms. Dickens sets this novel in the small, imaginary of Cloisterham (which means a monastery corridor),where church doctrines are absolute. He portrays the cathedral and the heroes working in or being influenced by it with Rabelaisian grotesque form, and shows how much all things in the residents" lives were being affected by the church. Through this narrative, Dickens succeeds in blocking his readers" negative response and carrying his critical massage effectively. So that his readers can enjoy reading, he characterizes Cloiterham Cathedral and the main characters by combining some imageries representing something noble, spiritual, transcendent, divine with other imageries expressing something low, animalistic or worldly. The mixture of such opposite and heterogeneous imageries results in letting his readers think about whether what they have believed is true, and recognize various problems of the Christianity and the politics they have supported without any direct and negative statements. In M. M. Bakhtin"s perspective, this narrative can be explained with the concept, "degradation," one of Rabelaisian stylistic characteristics. Also ,it enables Dickens to create grotesque and comical imageries in this novel and show how the church image is different from what his readers accept as normal. Furthermore, through parody of public culture, such as children"s plays and Christmas festivals, Dickens enhances the comicality both in characterization and narration as well as makes his readers enjoy reading. This can be explained as the Rabelaisian carnival-grotesque concept of liberation and resurrection in that it is not the criticism just for criticism.
