In this chapter, the Kumla Prison Monastery is discussed as an example of the ambiguous policy and practice of Swedish secular state institutions in relation to the field of religion. Kumla is the largest prison in Sweden, and one of the most protected and secure ones. It holds convicts serving long sentences. This prison conducts a very special activity, probably unique in the world: the ‘Monastery’, which allows convicts to undergo a long silent spiritual retreat, as initiated by Ignatius of Loyola, a sixteenth-century Catholic priest. Although Swedish official policy is that state authorities should be religiously neutral, this use of religion in prison illustrates a certain ambiguity of the Swedish secular state institution.
