'We have sick souls when God's physic works not': Samuel Rutherford's pastoral letters as a form of literary cure.

Samuel Rutherford's letters draw on biblical imagery and idiomatic metaphors, including contemporary discourses of illness and medicine, to diagnose and promote the spiritual and physical health of individual believers and the Scottish Kirk. This essay examines how Rutherford used language to care for his correspondents enacting a form of literary cure through the letter as a communication technology. Interrogating Rutherford's use of language theologically, politically, and practically to negotiate God's providential care for his people, the traumatic splintering of the church and state in England and Scotland, and caregiving within covenanting communities, reveals how his epistolary practice expands knowledge of the church's historical provision of care, and the intersection of religious and medical caregiving in early modern Scotland. Rutherford's lexical and metaphorical creativity, rendering complex theological concepts emotionally intelligible and rhetorically effective, ensured his letters provided comfort to covenanted godly communities and underwrote their posthumous publication as a devotional and literary classic.
