The intersection of whiteness and Christianity receive increasing academic attention and has been explored from different perspectives. Yet, despite scholarship on the whiteness of Christian identity in relation to racial prejudice or on the colorblindness of 'white' as an aesthetic ideal in Christianity, the construction of white discourses has not been examined thoroughly from the perspective of religious spaces. Drawing on a spatial approach, I investigate how the material and visual construction of whiteness dis/enables encounters with difference. The whiteness of places often goes unnoticed under the guise of neutrality, even though it reproduces hierarchies of visibility, reinforces dominant positions and constitutes what is out of place. Drawing on parish-based research in Belgium, I will combine material and visual analysis in order to examine performances of whiteness and diversity in symbols, objects, iconography and church design. In conversation with art-based research, I explore the limitations and possibilities of material engagement - as a situated participatory practice - to address unacknowledged whiteness. Ultimately, this presentation aims to contribute to a deeper understanding of spatial representations of whiteness as to create space for encounters with difference.
