This paper approaches the similarities and differences in the concepts and the narrative methods of Water Margin and Journey To the West from the perspective of theology. It purports to show the didactic purpose and function of the two works. The heroes in the two works show characteristics of the divine and of evil. They move in a three-phase progress: from the divine to a manifestation of evil and then back to the innate divinity. Rulers who use them wisely do so and create a cultured, peacheful, prosperous realm, and those who do not know how to use them turn the world into a battlefield. This is how the two authors use the three-phase progress of their heroes as an exemplar of good governance. The concept of the divine in the two works is an expression of the authors' concept of what is right. The concept serve three functions:a) as guiding principles for the progress of the heroes, b) as advocacy for the sense of justice in the heroes, and c) as an expression of the unstated purpose of the authors in the creation of the works. While both works use the "divine-human-divine" three-phase structure as the narrative structure of the novel, differences exist because of the differences in the aestheties of feeling, of ideals and of psychology in the two authors.
