"The historical Jesus will be to our time a stranger and an enigma. The study of the Life of Jesus has had a curious history. It set out in quest of the historical Jesus, believing that when it had found Him it could bring Him straight into our time as a Teacher and Savior. It loosed the bands by which He had been riveted for centuries to the stony rocks of ecclesiastical doctrine, and rejoiced to see life and movement coming into the figure once more, and the historical Jesus advancing, as it seemed, to meet it. But He does not stay; He passes by our time and returns to His own. What surprised and dismayed the theology of the last forty years was that, despite all forced and arbitrary interpretations, it could not keep Him in our time, but had to let Him go. He returned to his own time, not owing to the application of any historical ingenuity, but by the same inevitable necessity by which the liberated pendulum returns to its original position."

“A word in conclusion about the relations between the whites and blacks. What must be the general character of the intercourse between them? Am I to treat the black man as my equal or my inferior? I must show him that I can respect the dignity of human personality in every one, and this attitude in me he must be able to see for himself; but the essential thing is that there shall be a real feeling of brotherliness. How far this is to find complete expression in the sayings and doings of daily life must be settled by circumstances. The negro is a child, and with children nothing can be done without the use of authority. We must, therefore, so arrange the circumstances of daily life that my natural authority can find expression. With regard to the negroes, then, I have coined the formula: "I am your brother, it is true, but your elder brother."”

“Modern Christianity must always reckon with the possibility of having to abandon the historical figure of Jesus. Hence it must not artificially increase his importance by referring all theological knowledge to him and developing a ‘christo-centric’ religion: the Lord may always be a mere element in ‘religion’, but he should never be considered its foundation. (p. 402)”

“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 tasks which He has to fulfil 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.”

“The ideal "Life of Jesus" [biography] at the close of the nineteenth century is the "Life" which Heinrich Julius Holtzmann did not write — but which can be pieced together from his commentary on the synoptic gospels and his new testament theology. It is ideal because, for one thing, it is unwritten, and arises only in the idea of the reader by the aid of his own imagination, and, for another, because it is traced only in the most general outline.”

“Defined from outside and quite empirically, complete civilization consists in realizing all possible progress in discovery and invention and in the arrangements of human society, and seeing that they work together for the spiritual perfecting of individuals, which is the real and final object of civilization. Reverence for life is in a position to complete this conception of civilization and to build its foundations on what lies at the core of our being. This it does by defining what is meant by the spiritual perfecting of man and making it consist in reaching the spirituality of an ever-deepening reverence for life.”

“The awareness that we are all human beings together has become lost in war and through politics. We have reached the point of regarding each other only as members of a people either allied with us or against us and our approach; prejudice, sympathy, or antipathy are all conditioned on that. Now we must rediscover the fact that we — all together — are human beings, and that we must strive to concede to each other what moral capacity we have. Only in this way can we begin to believe that in other peoples as well as in ourselves there will arise the need for a new spirit which can be the beginning of a feeling of mutual trustworthiness toward each other.”
