John Piper posted an interesting quote on his blog yesterday. He writes,
J. Gresham Machen saw in 1933 what many are trying to say today about the need for private education.
The only way in which a state-controlled school can be kept even relatively healthy is through the absolutely free possibility of competition by private schools and church schools; if it once becomes monopolistic, it is the most effective engine of tyranny and intellectual stagnation that has yet been devised. (J. Gresham Machen: Selected Shorter Writings, 167)
