In the past two decades, Margaret Barker has managed a miracle: in a prodigious output of a dozen scholarly books and book chapters, as well as numerous articles and conference addresses, Barker, a Cambridge-educated independent scholar, Methodist lay preacher, and former president of the Society for Old Testament Study, has successfully shaken the very foundations of Old Testament and early Christian scholarship. Is it not obvious that the Christianity of Jesus' day and shortly thereafter was heavily influenced by Greek culture? Is it not clear that Jesus' teachings were a product of the Jewish culture, especially the synagogue culture, of his day? "No," says Barker to these claims; it is neither obvious nor clear that Christianity had its origin in these influences. A careful reading of noncanonical sources such as the Enoch literature and the Dead Sea Scrolls suggests that Jesus was influenced by something much more ancient than Hellenistic or synagogue culture. He seemed to have in mind the theology and ordinances of the first Jewish temple, the temple as it had existed before the accretions of paganism and the "reforms" of King Josiah in the seventh century BCE. Indeed, if Barker's thesis holds up to scholarly scrutiny, everyone will be forced to redefine Jesus as a restorer of a religion that had been lost rather than as an inventor of something new.
Such a reworking of centuries of scholarship will not be easy. Think of the scores of German Protestant scholars whose work constituted the academic foundation of intertestamental scholarship throughout the twentieth century and whose labors are now being called into question. Think of the millions of Christians of all stripes who have been taught to believe in a strict trinitarian monotheism—a belief Barker claims is inconsistent with both ancient Jewish religion and the religion Jesus restored. Despite these formidable obstacles, the Germans are diligently reading Barker and are finding much of value, as are the Catholics, the Russian Orthodox, and many others. At least sixty reviews of Barker's works have already been published (including the lead review in the Times Literary Supplement of 2003), and Barker has been asked to speak at conferences and symposia in Europe, Turkey, and the United States, including at a Brigham Young University devotional in 2003 and at the Joseph Smith Conference in Washington, D.C., in 2005.
