In this article, I examine early religious literature in the Albanian language in the seventeenth and eighteenth centuries, which, in combination with ecclesiastical rivalries and a differential opposition to Ottoman rule, must have promoted an inherent cultural process of differentiation, especially between Greek-speaking and Albanian-speaking Orthodox Christians. In particular, I argue that the contradicting motivations of political contradistinction, Enlightenment propagation, Orthodox evangelism, ecclesiastical confrontation, and missionary counteraction lead inadvertently to a boundary work of the social reorganization of linguistic and cultural difference.
