Ioannis Calvini Opera quae supersunt omnia: Ad fidem editionum principum et authenticarum ex parte etiam codicum manu scriptorum, additis prolegomenis literariis, annotationibus criticis, annalibus Calvinianis indicibusque novis et copiosissmis

This monumental collection, commonly known as the Corpus Reformatorum series, was compiled and published in the mid-to-late 19th century by scholars Wilhelm Baum, Eduard Cunitz, and Eduard Reuss. The project was initiated to provide a comprehensive and definitive critical edition of the theological writings, sermons, and correspondence of Jean Calvin, the French reformer. It was intended to serve as a scholarly foundation for historical and theological inquiry, replacing earlier, less systematic compilations of Calvin’s work.

The editorial team utilized the original editions of Calvin’s publications and cross-referenced them with extant manuscripts to ensure textual accuracy. The inclusion of critical annotations, historical annals, and exhaustive indices transformed the set into an essential resource for academics. Upon its release, the work was widely received as the authoritative standard for Calvinian studies, a reputation it has maintained among historians and theologians for over a century.
