This article examines the so-called post-Foucauldian genealogy of power undertaken by the Italian philosopher Giorgio Agamben. His basic interest is why and in which ways power assumed the form of economy, which, according to Foucault’s genealogical research, means the “government of men”. For Foucault, the origin of managerial-administrative power is the paradigm of a pastorate, in which the main objective is to subjugate, control and govern the soul of every human being. For Agamben, the time horizon determined by Foucault is not sufficient. Therefore, he developed a theory of bio-power and bio-politics through the paradigm of economic theology, using a wide range of materials from the early medieval period to the 20th-century theology. Using archaeological and genealogical methods, this investigation aims to show the process of a paradigm shift from political to economic theology within the context of power relations. Moreover, it tries to verify whether Agamben’s assumption is correct. By analysing certain concepts such as divine anarchy and collateral effect, I intend to question whether the Christian economy, as action and administration, is an archetype of the modern form of power or not.
