Patrologiae cursus completus

The Patrologiae cursus completus is a monumental collection of writings by early Christian authors, compiled by French priest and publisher Jacques-Paul Migne in the 19th century. This extensive series is divided into two main parts: Patrologia Latina, which contains the works of Latin ecclesiastical writers up to Pope Innocent III, and Patrologia Graeca, featuring the writings of Christian Greeks up to 1439.1

This collection is invaluable because it preserves many texts that are otherwise difficult to find. It is considered a foundational resource for studying patristic literature, which encompasses Christian writings from before the 8th century. Migne's goal was to make these important theological works accessible at affordable prices.12
