This short contribution aims to map the impact of religion on the European Parliament elections in 2024. After retracing the complex position of religion within the European Union, the article addresses the relevance of religious concerns in supranational politics against the background of the relative decline of Christian democracy, the emergence of populism, and the emergence of identitarian constitutional narratives in which religion plays a significant role. A comparative analysis of the manifestos of the main European political parties shows that religion, despite its relatively minor role, is far from being irrelevant and may be relied upon for several purposes.
