Combining theological and medical perspectives is indispensable for the historical study of the interconnections between mind, body, and soul. This article explores these relations through the history of Finnish psychosomatic medicine, and uses published and archival materials to examine the intellectual biography of the Finland-Swedish theologian turned psychiatrist Asser Stenbäck (1913–2006). Stenbäck's career, which evolved from priesthood to psychiatry and politics, reveals a great deal about the tensions between religion and medicine, the spiritual and scientific groups that impinged upon psychosomatic (...) medicine, and ideas on how health and Christian morality were interconnected. The biographical approach is adopted to unearth the values encoded in medical concepts, and through this, to point towards another, underexplored dimension of the health–religion relationship. In addition to their emotional aspect, religious doctrines are intended to organise life and give it meaning. Stenbäck's ideas tied these experiential and normative spheres together by defending an irrationalist substratum of the world in the secular age of medicine. His work illustrates how the inner experience of faith can become both medically and politically purposive. It is worth combining these perspectives in historical research as well in order to better understand how the theological, medical, and political worlds are in dialogue when it comes to human problems.
