I know less about Albert Schweitzer than I probably should, but what a way to end a book:

He comes to us as One unknown, without a name, as of old, by the lake-side, He came to those men who knew him not. He speaks to us the same word: ‘Follow thou me’ and sets us to the task which He has to fulfill for our time. He commands. And to those who obey Him, whether they be wise or simple, He will reveal Himself in the toils, the conflicts, the sufferings which they shall pass through in His fellowship, and as an ineffable mystery, they shall learn in their own experience Who He is.

From Von Reimarus zu Wrede: eine Geschichte der Leben-Jesu-Forschung (1906; English: The Quest of the Historical Jesus, 1910)
