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.

04

Religion, cohesion and public policy

Research with direct policy relevance: prevention of radicalisation, transnational religious governance through mosque sermons, citizenship and religious education, and polarisation in public debate.

“
Since the 1980s, Turkey has used Friday sermons to convey the state’s and religious authorities’ interpretations of Islam to a wide public.
Since 2002, sermons on religious and ethnic minorities by Diyanet and its Dutch branch passed through three stages: plurality, superiority, and polarisation and suppression.
The ethos and institutional culture of Turkey’s Presidency of Religious Affairs changed markedly within fifteen years.
In recent years, Friday sermons were intensively modified to safeguard Sunni Islam and to monopolise the Turkish interpretation of Islam.
Growing nationalist and authoritarian tendencies in Turkey turn Diyanet’s informal religious education into a vehicle for ultra-nationalist ideas.
