In this broad survey of the efforts to establish, amend, or deny the historical Jesus, Albert Schweitzer presents the history of a debate about what mattered most to millions of people: If God had entered human history, what could history tell about it? Throughout the course of this heated and prolonged dispute, one retelling of the life of Jesus followed another, enjoying -- in Schweitzer's phrase -- "the immortality of revised editions." Lesser writers might consider differences of opinion as signs of a hopeless enterprise, but Schweitzer instead finds immense value in the differences. Approaches and conclusions may differ, he concludes, but the quest for the historical Jesus has provided ample testimony to the importance of the effort and the rewards of the experience.
