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)(HT: Desiring God Blog)
No, Machen is not a contemporary politician, he wrote those words in 1933.
"If our theology does not quicken the conscience and soften the heart, it actually hardens both; if it does not encourage the commitment of faith, it reinforces the detachment of unbelief; if it fails to promote humility, it inevitably feeds pride."(HT: Vitamin Z)
