Raymond of Penyafort - Gregorian Decretals

Gregorian Decretals

Knowing Raymond's reputation in the juridical sciences, Pope Gregory IX summoned him to Rome in 1230 to help in the rearranging and codifying of canon law. Canon laws, which were previously found scattered in many publications, were to be organized into one set of documents. In particular papal decretal letters had been changing the law over the course of the previous 100 years since the publication of the Decretum of Gratian. Being pleased with Raymond's efforts, the pope announced the new publication in a Bull directed to the doctors and students of Paris and Bologna in 1231, commanding that the work of Raymond alone should be considered authoritative, and should alone be used in the schools. His collection of canon law, known as the Decretals of Gregory IX, became a standard for almost 700 years. When Raymond completed his work, the pope appointed him Archbishop of Tarragona, but he declined the honour. Raymond followed this with the publication of a work on penitential discipline, Summa casuum, which is widely considered an authoritative work on the subject. Canon law was finally fully codified by 1917.
