The Epistle of St. Paul the Apostle to the Romans is one of the letters of the New Testament canon of the Christian Bible. Often referred to simply as Romans, it is one of the seven currently undisputed letters of Paul. It is even counted among the four letters accepted as authentic (known in German scholarship as Hauptbriefe) by Ferdinand Christian Baur and the Tübingen School of historical criticism of texts in the 19th century.
