The paper intends to investigate the role occupied by religious authority and religious discourse in the political field. Autocracy, hence, is scrutinized as an entranceway to the matter of religion in the construction of a hegemonic rhetoric of domination. Subsequently, the theological field is studied in seek for tools to the analysis of religion as a moral platform to the edification of absolute truths, which will resonate in the exercise of political power. Therefore, the antagonism existent in the core of democracy is highlighted, leading to the construction of a criticism to modern liberalism, upheld on the reconsideration of religion on its preeminent position. The conclusion presented, therefore, aims for the overcoming of classic illuminist thinking, in favor of revaluing the role played by religious rhetoric in the public sphere and promoting an effective democratization of religion as part of the project of constitutional liberalism.
