The presentation aims to show the potential of the postsecular approach in identifying and interpreting religion in so-called Eastern Europe. The first part of the presentation will present a critical overview of the use of the postsecular framework or terminology in current studies on the region. The context will be the epistemic prejudices that refer directly to the (post-Reformation) notion of the religious. It will be suggested that they manifest themselves mostly in the relationship between religious and secular powers, as well as the idea of religious pluralism and tolerance. In this context, the question of the Russian model as still predominant in scholarship will be raised. The second part will be devoted to a typology of postsecular approaches which refers directly to the ambivalent status of the region as the closer-to-home Other, which is part of Western civilisation, yet is misrepresented and misunderstood geopolitical prejudices and cryptotheological entanglements. Ultimately, it will be pointed out that one of the approaches - the deconstructionist one - would contribute in particular to current attempts to overcome scholarly biases and inaccurate epistemologies. It would also help with in interrogating the presuppositions about the Western (European) Self, including those concerning Christianity as a presumably 'Western' religion.
