Albert Schweitzer in "The Quest for the Historical Jesus," acknowledges that Reimarus's work "is a polemic, not an objective historical study", while also referring to it as "a masterpiece of world literature." According to Schweitzer, Reimarus was wrong in his assumption that Jesus's end-of-world eschatology was "earthly and political in character" but was right in viewing Jesus as an apocalyptic preacher, as evidenced by his repeated warnings about the destruction of Jerusalem and the end of time. This eschatological approach to understanding Jesus has since become universal in modern biblical criticism. Schweitzer also comments that, since Reimarus was a historian and not a theologian or a biblical scholar, he "had not the slightest inkling" that source criticism would provide the solution to the problems of literary consistency that Reimarus had raised.
