Calvin published “The Institutes of the Christian Religion” in Latin, preceded by an Address to King Francis I. The work, published in Basel, presents the theological and biblical foundations of the Reform and their consequences. He bases himself on Luther’s theology – justification by faith; salvation through grace – not without assigning it consequences that are often quite different, particularly concerning the organization of Churches, the liturgy, the relationship with the world. Other editions in French followed.
