The Corpus Catholicorum (Corp. Cath., CCath., or CC) is a collection of sixteenth-century writings by the leading proponents and defenders of the Roman Catholic Church against the teachings of the Protestant reformers.
The full title of the series is: Corpus Catholicorum: Werke katholischer Schriftsteller im Zeitalter der Glaubensspaltung, i.e., Body of Catholic [writings]: Works of Catholic authors in the Time of the Splitting of the Faith.
The series, intended as a counterpart to the Corpus Reformatorum, was conceived in 1915 by Professor Joseph Greving (1868–1919) of the University of Bonn, and was announced that same year in the Theologische Revue as a "Plan für ein Corpus Catholicorum" or "Plan for a Corpus Catholicorum."[1]
