Final answer:
The term 'double cure' in Christian theology indicates a dual aspect of salvation, involving both spiritual healing and forgiveness of sins. It is inherently linked with both the spiritual and social realms, with baptism, confession, and penance being key elements.
Step-by-step explanation:
The term double cure refers to a concept within Christian theology that represents a twofold aspect of salvation: spiritual healing and forgiveness of sins. This dual aspect speaks to the idea that the spiritual and social elements of life are interwoven. The physical healing of sickness often had spiritual implications. In the context of the question, the best interpretation of the term would likely be 'Forgiveness from original sin and its expression in the life of a believer'. This involves both the cleansing from original sin, often symbolized through the practice of baptism, and the transformation and sanctification that is meant to occur in the life of the believer, which is an ongoing process involving confession and penance.
Much of medieval Christian practice was deeply intertwined with both social and spiritual components, often blending physical healing with spiritual salvation. The practice of confession, for instance, was intended to address the spiritual state of the individual, while pilgrimages and the laying on of hands served to combine physical action with spiritual theory and belief.
