The thesis aims to demonstrate the theological foundations that determined the romanesque work of F. Dostoevsky. Based on the traces of the long tradition of religious commentators of his work, as V. Ivanov, N. Berdyaev, P. Evdokmov, the paper identifies in Dostoevsky’s work a theology that found in tragedy, and not in the classical philosophy of tradition from Plato and Socratic, its foundations and elective affinities. Possessing an anarchic configuration devoid of metaphysical foundations, theology of Dostoevsky became the most significant symptom of the modern tragic thought, manifesting itself as a religious criticism of all romantic-rationalist systems that have established from the Hegelian Aufhebung, which is composed as the constitutive element of modern materialistic reconciliation. As tragic reflection, Dostoevsky s Christianity opened the theological problem in modernity, outside the frames of metaphysics, anticipating the tragic stalemate and radical theological insufficiency of modern materialism.
