Paul Christian - A Jewish Dominican Preaching for the Jews

The so-called Barcelona disputation of 1263 was one of the earliest Jewish-Christian disputations in medieval Europe. The disputants were Paul Christian, a Jewish convert to Christianity and member of the Dominican order, and the well known Jewish sage Ramban (Rabbi Moses ben Nahman of Gerona). In the disputation Paul Christian used an innovative method: he attempted to prove the truth of basic Christian dogma, for instance that the Messiah had already come, by using classical Jewish texts, especially the Talmud. Paul Christian used the same method in his sermons which the Jews in the area were forced to listen to. When one analyses the arguments he employs, it becomes obvious how he alludes to both Jewish and Christian traditions in order to convince his listeners.
