Current literature about religion in higher education typically emphasizes belief as a central component of religious identity. Through framing this discourse with a critical social justice lens, I argue that there needs to be a purposeful distinction between religious/spiritual belief and religious identity/culture in order to acknowledge the socio-cultural nature of religion and to more clearly understand the privilege/oppression dynamic associated with it. By describing the way Christian privilege and religious oppression are often independent of individuals' religious or spiritual beliefs, I discuss implications of this over-emphasis on belief for religious minorities and explain how focusing instead on religious culture can help make campus-based interfaith initiatives more social justice oriented.
