Interesting article. I can think of even two more significant reasons: Firstly the Bible is true. Secondly, only the Bible can provide the worldview coherence that education necessitates.
Why? Why shouldn’t elements of the Bible be taught in public schools? It has had an unparalleled impact on Western culture, history, music, the arts, politics, morality, law and literature. Are we embarrassed about our country’s foundations or, worse, have we become intellectual cowards?
