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.

“
Among Dutch-Turkish Muslims, high religiosity takes different forms and rests on different motivations; there is no single way of being a devout Muslim.
The distinction between the “great” and “little” traditions of Islam is key to understanding the religious life of Turkish Muslims, in Turkey and in the diaspora.
For Muslims in Europe, the real question is not whether one is a believer, but whether the content of one’s belief makes one open to others or ethnocentric.
The economic disadvantages of immigrant life play an important role in the kinds of religiosity Muslim migrants choose on Europe’s religious market.
Dutch-Turkish Muslims express their faith through particular religious voices, and these voices can be expected to change as their circumstances change.
As the economic position of Muslim migrants in Europe improves, a more reflexive and spiritual form of religiosity can be expected to develop in the long term.
