With the increasing prominence of religious issues, the “theological turn” in Eagleton’s theory has gradually drawn attention of academics in China. In his theory, Eagleton constructs a god who values creativity, cares for others, and bears the responsibility of crime. Through interpretation of ideal theology, Eagleton constructs a common culture that can be jointly built and shared. This practice continues and develops the attempt of the New Left in Britain to explore the socialist goal through “cultural politics”. The theoretical innovation originates from the conundrum of practice. Compared with Raymond Williams, Eagleton needs to find the power to transform theoretical thinking into social practice in the context of the fading tide of politics, the culture of individualism and fragmentation. Theology thus has become both the resource to deal with problems and the method to conceal the practical conundrum.
