Is the US Constitution based on secular, Judeo-Christian values or Social Darwin theory?

I believe the US Constitution, as amended is based on Judeo-Christian values which supports a free market capitalism system based on Social Darwinist's form of government.

The constitution itself without the amendments is a stand alone proof of Social Darwinist's value... the amendments added shortly after represent Judeo-Christian values.

Do you agree or disagree and why?
