"Especially do the evils of the times, the folly and blindness of the masses, the injustice of rulers, the perversion of religion in unfruitful ceremonialism work upon the souls more finely attuned as a stimulus and spur; the feeling of the evil stirs their moral judgment or conscience to the criticism of the existing situation, and out of the criticism there grows for them the new ideal which impresses itself upon them as the truth that has the power to save from the corruption of the time; and while they first raise themselves to this ideal, they also win power and courage to draw others toward it. Thus they become the proclaimers of a higher truth which, over against the antecedent error, appears as something wholly new, as a revelation from above, but which is, indeed, nothing else than a higher development of the impulse toward truth and righteousness that is a natural quality of the human mind."

“The fundamental error of the theologians of the new faith of the present day consists in this, that they think one can without hesitation acknowledge the validity of the same scientific method in the realm of nature which they refuse to apply to that of history. ... What consequence now will follow the application of the doctrine of evolution to the theological consideration of history? First of all, it is evident that it excludes miracles in every sense of the word—not merely the nature-miracle but also just as much the spirit-miracle, i.e. the intervention of a foreign power in the human soul, whereby conditions are produced in it which do not result from the causal connection with antecedent conditions. If it is the methodic cardinal proposition of the science of today that we have to explain every condition as the causally determined development out of a preceding one, this excludes on principle the appearance of a condition, event, action, or personality which is not explicable out of the factors of the preceding conditions.”

“The divine in Jesus does not denote a violent rupture of the course of human history with the exclusion of all causal connection and all human personality, but it lies at the basis of all this history from beginning to end; it dwells in it as the divine Logos, as the rational aptitude of human nature, as impulse to the true and good, as God-consciousness. All progress in the development of mankind from the lowest grades upward, every achievement of culture which makes rude nature the servant of reason, every formation of higher ethical ideals, and every clarifying and deepening of the God-consciousness, is an effect and a revelation of the divine Logos dwelling in our race.”

“Here is the basis of the modern critical biblical science, which treats the documents of Christianity and Judaism according to the same principles of historical investigation which are valid in all other historical domains, particularly in that of the history of the ethnic religions.”

“It is a hyperbole excusable in poetic language, but not scientifically valid, when he is identified with the ideal of humanity. The ideal is the unconditioned, the absolute, but every phenomenon in time and space is conditioned and limited, and cannot therefore coincide with the ideal. This hyperbole of pious faith may grow out of noble feelings, but for all that it remains essentially false, and is harmful when seriously regarded as dogma.”
