Excommunication for Debt in Late Medieval France

Using quantitative and qualitative methods to re-evaluate the role of late medieval church courts, Tyler Lange examines the relatively common occurrence of excommunicated debtors. This reveals how day-to-day credit functioned in the late Middle Ages, what debt meant to contemporaries, and how believers understood the Church.

Late medieval church courts frequently excommunicated debtors at the request of their creditors. Tyler Lange analyzes over 11,000 excommunications between 1380 and 1530 in order to explore the forms, rhythms, and cultural significance of the practice. Three case studies demonstrate how excommunication for debt facilitated minor transactions in an age of scarce small-denomination coinage and how interest-free loans and sales credits could be viewed as encouraging the relations of charitable exchange that were supposed to exist between members of Christ's body. Lange also demonstrates how from 1500 or so believers gradually turned away from the practice and towards secular courts, at the same time as they retained the moralized, economically irrational conception of indebtedness we have yet to shake. The demand-driven rise and fall of excommunication for debt reveals how believers began to reshape the institutional Church well before Martin Luther posted his theses.
