Both church and state in sixteenth-century Protestant Geneva helped to resolve local disputes, particularly over issues of sex, marriage, and family which dominated the proceedings during John Calvin’s tenure from 1541 to 1564. The Genevan Consistory, comprised of pastors and political officials, was a preliminary hearings court with power to summon and examine witnesses and documents, and to issue spiritual sanctions from admonition to excommunication in an effort to reconcile disputants, reform delinquents, and restore legal and moral order in the city. But the Consistory left it to the Genevan City Council to prosecute serious offenses and offenders, and to issue legal orders respecting divorce, inheritance, marital property, child custody, and other legal issues. This Article sketches this new collaborative regime of dispute resolution, and then analyzes several illustrative cases from the Consistory records.
