A keen student of theology, August Friedrich Gfroerer (1803-61) became professor of history at the University of Freiburg and also sat as a representative in the Frankfurt parliament, agitating for the reunification of Protestantism and Catholicism. This three-volume work, published in 1838, may be regarded as marking the modern period in the Christian study of Judaism. Gfroerer was the first scholar who attempted to recount the history of Palestinian Judaism at the time of Jesus by using primary source material and without pursuing an obvious apologetic or polemic agenda. More than 2,000 pages in length, the work is a formidable scholarly achievement of lasting value in the field of religious studies.

A keen student of theology, August Friedrich Gfroerer (1803-61) became professor of history at the University of Freiburg and also sat as a representative in the Frankfurt parliament, agitating for the reunification of Protestantism and Catholicism. His academic work marked the modern period in the Christian study of Judaism, making full use of primary sources without pursuing an obvious apologetic or polemical agenda. This two-volume work, published in 1831, is a critical study of early Christianity and the influence that Judaism had on the New Testament. Volume 1 provides a thorough exposition of Philo of Alexandria's philosophy and theology in addition to a biographical sketch. Volume 2 is devoted to substantiating the thesis that the core principles of Philo's theology were already discernible among the Alexandrian Jews.
