Religious reasons in the public sphere: an empirical study of religious actors' argumentative patterns in Swiss direct democratic campaigns

The ‘going public’ of religious actors is taking central stage both in religious studies and political philosophy. But this ‘going public’ of religious actors is controversial. The debate revolves around the question of whether religious actors must frame their religious convictions in terms of secular reasons or whether they should be allowed to introduce religiously grounded beliefs into public political argument without constraints. Despite vigorous and ongoing debate, there is little systematic and empirical research on this question. This article focuses on the public statements of religious actors in the context of Swiss direct democratic votes on abortion and immigration. Our empirical findings reveal an interesting gap: while many political philosophers and religious thinkers have moved to a position where religious actors can – and even should – openly employ religious arguments, the practice of religious actors in Switzerland is different.
