R.J. Rushdoony wrote this essay over 20 years ago, as that lamentable 20th century was winding down.

In a very few words (quite an achievement!), Rushdoony summed up that century’s “heritage of failure” as worldly schemes for salvation, one after another, had their days in the sun and went promptly belly-up. We tried everything we could think of–except God’s word–and it all failed us: politics, education, money, and war. Even a pagan like Robert Graves saw his own 20th-century world as an unholy alliance of Mars, the god of war, Pluto, the god of wealth, and Mercury, the god of thieves.
But the answers, Rushdoony knew, were to be found in the same place where they’ve been always found–in God’s own enscriptured word.
