In this article, the aim is twofold: firstly, to explore, through a systematic literature review, what discourses on religion may be identified in previous research that focuses on students' perspectives, and secondly, to discuss this in relation to research concerning challenges and opportunities in Scandinavian religious education (RE) and classroom negotiations, which is presented as a background to and scientific landscape for the study. Seven discourses relating to students' understanding of religion have been identified in the text sample from the systematic review, religion as: "threatening," "a relic," "needing to be tolerated," "truth claims," "plastic," "source of existential curiosity," and "security and comfort." The findings show how these discourses together constitute a broader repertoire of discourses on religion than can be found in the Scandinavian RE classroom research presented as a frame for the study, especially when taking into account current orders of discourse and dominance structures. As stressed by discourse theory and sociocultural perspectives on learning, having access to broad repertoires of discourses on religion provides a basis for more nuanced ways of thinking about religion. It is vital that teachers are aware of this and can challenge dominant discourses and broaden existing repertoires. An important step in such a direction is an awareness of discourses on religion, such as the seven presented here, which may potentially be present in the classroom, even in practices other than the ones these discourses emanated from.
