Non-Christian education puts the child in a vacuum, the result is that the child dies. Christian education alone really nurtures personality because it alone gives the child air and food. Modern educational philosophy gruesomely insults our God and our Christ; how then do you expect to build anything positively Christian or theistic upon a foundation which is the negation of Christianity and theism. No teaching of any sort is possible except in Christian schools.
— Cornelius Van Til, quoted by Voddie Baucham in “Whoever Controls the Schools Rules the World” at 21:48
