The twentieth century witnessed a lively debate over the extent of Hellenization in the Levant, particularly among the ancient Jews, which has continued until today. Interpretations on the rise of Early Christianity, which was applied most famously by Rudolf Bultmann, used to see Judaism as largely unaffected by Hellenism, and the Judaism of the diaspora was thought to have succumbed thoroughly to its influences. Bultmann thus argued that Christianity arose almost completely within those Hellenistic confines and should be read against that background, as opposed to a more traditional Jewish background. With the publication of Martin Hengel's two-volume study "Hellenism and Judaism" (1974, German original 1972) and subsequent studies "Jews, Greeks and Barbarians: Aspects of the Hellenisation of Judaism in the pre-Christian Period" (1980, German original 1976) and "The 'Hellenisation' of Judaea in the First Century after Christ" (1989, German original 1989), the tide began to turn decisively. Hengel argued that virtually all of Judaism was highly Hellenized well before the beginning of the Christian era, and even the Greek language was well known throughout the cities and even the smaller towns of Jewish Palestine. Scholars have continued to nuance Hengel's views, but almost all believe that strong Hellenistic influences were throughout the Levant, even among the conservative Jewish communities, which were the most nationalistic.
