"Just as the wave cannot exist for itself, but is ever a part of the heaving surface of the ocean, so must I never live my life for itself, but always in the experience which is going on around me. It is an uncomfortable doctrine which the true ethics whisper into my ear. You are happy, they say; therefore you are called upon to give much."

“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.”
