The existential view of theology centered at Christ and trinity posed by Moltmann is deeply discussed in this essay, starting with the method of theological study of Moltmann. A concrete analysis of the existential modes of apostles, martyrs, monks and the weak living at the bottom of society has been carried out. The essential difference between the existential view of theology of Moltmann and that of the Evangelical circles is highlighted, and Moltmann's existential theology of mental and political liberation about breaking away from all kinds of vicious cycles in a realistic society is also reviewed.
