Recent struggles over the implications of migration have fueled transformational politics on both sides of the Atlantic. At the center of this are questions of identity, value, long-standing standards of human rights and even enlightenment categories of modernity. Both religion and media play central – even determinative – roles in these debates. This article will argue that scholarships focused on identity “imaginaries” are critical to understanding these discourses and this politics. This scholarship must inquire into both “sides” of migration, both the conceptual worlds of those who wish to move, and the conceptual worlds of those who receive (or attempt to not receive) them. This article will look at the latter through a deep historicist inquiry into the mediation of Protestantism as a central determinative force in the establishment of contemporary conditions of politics in relation to migration in the North Atlantic West. Protestantism’s role in European modernity is well-known, as is its deep interconnection with evolving technologies and means of communication and practices of mediation. This article seeks to understand religion-inflected discourses of nationalism and identity as functions of Protestant social and media instrumentality.
