In 1893 Asa Gray of Harvard, one of the first advocates of theistic evolution recognized the conflict between evolution and theism. The God implied by evolutionary theory and the data of natural history is not a loving God who cares about his productions. He is careless, indifferent, almost diabolical. I will answer your question about evolution leading to atheism in a later column. As a result, the whole biblical system of salvation collapses .
Evolution thus becomes the most potent weapon for destroying the Christian faith.
That new faith is not necessarily outright atheism, since this is only for the very few, for the dedicated purist. It is tailor-made for those for whom there is still a need to satisfy the worship principle. In the mid 1800's Harvard and Yale were considered strong, orthodox Christian colleges, but by the end of the century they had abandoned these beliefs to become what they are today. Perhaps with the efforts of Asa Gray at Harvard and James Dana at Yale. He was one of the earliest and loudest advocates of theistic evolution.
