To the greater part of the church, when in 1859, after twenty years of work in accumulating the proofs of his theory, he at last gave it to the world, it seemed quite as bad as murder. It is very interesting now to look back upon the history and career of the Darwinian theory in the last thirty years; to recall, first the fierce outcry and denunciation it elicited, then the gradual accumulation of corroboratory evidence from all quarters in its favor; the accession of one scientific authority after another to the new views; the softening, little by little, of ecclesiastical opposition; its gradual acceptance by the broad-minded alike in theological and scientific circles; then, in these recent years, the exaltation of the new theory into a scientific and philosophic creed, wherein matter, force, and evolution constitute the new trinity, which, unless the modern man piously believes, he becomes anathematized and excommunicated by all the priests of the new dogmatism. In the field of science, undoubtedly, evolution has won the day. Nevertheless, in religious circles, old time prejudices and slow conservatism, clinging to its creeds, as the hermit crab clings to the cast-off shell of oyster or clam, still resist it. The great body of the Christian laity looks askance on it. And even in progressive America, one of the largest and most liberal of American denominations has recently formally tried and condemned one of its clergy for heresy, for the publication of a book in which the principles of Evolution are frankly adopted and applied to Christianity. For a man to call himself a Christian Evolutionist is (we have been told by high Orthodox authority) a contradiction in terms. I think it is safe to say to-day that Evolution has come to stay. It is too late to turn it out of the mansions of modern thought. And it is, therefore, a vital question, "Can belief in God, and the soul, and divine revelation abide under the same roof with evolution in peace? Or must Christianity vacate the realm of modern thought and leave it to the chilling frosts of materialism and scepticism?" Now, if I have been able to understand the issue and its grounds, there is no such alternative, no such incompatibility between Evolution and Christianity. There is, I know, a form of Evolution and a form of Christianity, which are mutually contradictory.
