Robert L. Dabney (1820–1898), Southern Presbyterian theologian and pastor, predicted the secularization of the public schools back in the 19th century. Dabney was a man who could see the logical outcomes of the policies of his day:
But nearly all public men and divines declare that the State schools are the glory of America, that they are a finality, and in no event to be surrendered. We have seen that their complete secularization is logically inevitable. Christians must prepare themselves then, for the following results: All prayer, catechisms, and Bibles will ultimately be driven out of the schools.
