Pauline Epistles
See also: Paul of Tarsus and JudaismThe theory is further developed in a later work (1835, the year in which David Strauss' Leben Jesu was published), Über die sogenannten Pastoralbriefe. In this Baur attempts to prove that the false teachers mentioned in the Second Epistle to Timothy and Epistle to Titus are the Gnostics, particularly the Marcionites, of the 2nd century, and consequently that the Pastoral Epistles were produced in the middle of the 2nd century in opposition to Gnosticism.
He next proceeded to investigate other Pauline epistles and the Acts of the Apostles in the same manner, publishing his results in 1845 under the title Paulus, der Apostel Jesu Christi, sein Leben und Wirken, seine Briefe und seine Lehre. In this he contends that only the Epistle to Galatians, First and Second Epistle to the Corinthians and Epistle to the Romans are genuinely Pauline, and that the Paul of the Acts of the Apostles is a different person from the Paul of these genuine Epistles, the author being a Paulinist who, with an eye to the different parties in the Church, is at pains to represent Peter as far as possible as a Paulinist and Paul as far as possible as a Petrinist.
