This is a really bad article. I'm not going to give it the full fisking.
The Bible is the foundation, the Declaration is the “why,” and the Constitution is the “how” of this wonderful experi-ment in liberty and self-government known as the United States of America....It took 18 centuries of Christian thought to produce the Declaration.
Instead of relying on Mr. Pastore's twaddle, read the Founding Fathers themselves. In particular, here is Jefferson on the ideological sources of the Declaration and notice that Christianity and the Bible aren't listed: "Aristotle, Cicero, Locke, Sidney, &c. ..." Similarly, neither the Federalist Papers nor the Constitution mention Christianity and the Bible.
The article also has gratuitous insults of atheists, evolutionists, and secularists.
