Abstract: Although research on religion, health, and wellbeing has flourished over the past decade, it has received little attention in theological circles, and the general impression is that such research and its interesting findings may not be of interest to theologians concerned with the proper hermeneutics of Christian revealed texts. Two questions could motivate greater engagement between the two fields. The first concerns the question posed above: what can theology learn from this body of research and its indications about the positive effects of religion? The second goes in the opposite direction: to what extent can theology contribute to refining and better understanding or applying such research? For example, greater theological involvement could help answer several open questions in this research, such as those concerning different types of religion and their effects; how to better understand and avoid misconceptions about the healing effects of religion; and how to avoid a complete instrumentalisation of religion as a result of these encouraging data. All this information can assist to better design and apply forms of spiritual care.
