How religion is lived, argued and imagined in contemporary Europe
Dr. Ömer F. Gürlesin is a sociologist of religion. His research looks at how religious meaning, moral orientation and authority take shape in everyday life and public debate, with a focus on Islam in Europe, the Sufi tradition and, more recently, religious language in climate discourse. He is a fellow researcher at the Center for Religion in the Public Sphere (CRiPS), Tilburg University.

Research with direct policy relevance: prevention of radicalisation, transnational religious governance through mosque sermons, citizenship and religious education, and polarisation in public debate.
In 310 Friday sermons of the Islamic Foundation Netherlands (2017–2023), a state-sponsored civil religion of Turkish nationalism and Islamism outweighs a liberal, pluralistic one.
The word for “nation” appears some 345 times in these sermons, mostly in reference to Turkish national identity rather than a community of faith.
Of 72 mentions of “Holland” in the sermons, only 17 concern the Muslims who actually live in the Netherlands.
Religious, national and homeland identities are woven together in the sermons rather than kept apart.
Without naming them, the sermons cast political opponents such as the Gülen movement as deceitful, using the concept of taqiyya.
Diyanet has become one of the most significant religious authorities shaping the hybrid identity of Turks abroad, reproducing an “us versus them” divide.
