Applying a qualitative framing analysis, this paper examines narratives of the right-wing populist parties Alternative for Germany (AfD) and the Party for Freedom (PVV) in the Netherlands on religion. The paper argues that references of these populist parties to religion can be interpreted against the background of specific national context factors such as the respective history of nation building, the traditional role of religion in society and secularization processes. A rigorous examination of parliamentary documents published between 2017 and 2019 shows that whereas the PVV clearly defines Christianity in civilizational and not religious terms, the AfD takes a less clear-cut stance toward the religion framing it both as culture and faith. We contend that this difference can be explained by the lower degree of secularization and the greater role of Christianity as a collective identity marker in post-war Germany.
