One of the most effective ways to overturn a culture is not to take it on directly, but to undermine it gradually. If you carry out a full-frontal assault on majority opinion, people become alarmed and fight back. But when you do it slowly, step-by-step, you can make your destruction look harmless... even reasonable.
That's exactly what's happening in this country.
For the past half century, there has been a slow but unrelenting attack on the Christian foundations of the United States. The evidence is beyond dispute. First, secularists took prayer out of the public schools, because it "promoted religion and alienated non-believing children." Even a simple moment of silence was too threatening.
Then they wanted the study of the Bible taken out of schools, because that "promoted Christianity." Never mind that the Scriptures form the basis of Western civilization and thought, and have inspired believers and non-believers alike over the centuries. Try reading Shakespeare or Dante or Robert Frost or just about any of the classics of Western literature without some familiarity with the Bible, and you'll be lost.
Of course, public monuments listing the 10 Commandments had to go, too, because displaying the moral foundation of Western law somehow endorsed Judeo-Christian religion. In 2003, Roy Moore, the former Chief Justice of the Alabama Supreme Court lost his post for refusing to remove one such monument from the state courthouse.
That wasn't the only display non-believers wanted gone. Every year, there are fewer nativity scenes on display in places where they've been seen and appreciated for years. Just last week, the New Jersey Department of Transportation removed a nativity scene from the St. George Ferry Terminal. They let a Christmas tree and a menorah remain, with one clueless city representative claiming a menorah isn't a religious symbol (he might want to take a look at Exodus 25:31-40).
