You nailed it, LQ. The "arguments" stated above are exactly the same as those used by the mullahs in Iran, or the Taliban in Afghanistan.
This is one of the reasons that Jefferson used "Natures God" and not any single religions "god" in the Declaration of Independence, and why the Constitution forbids the establishment of a State religion in the Bill of Rights.
It's also one of the more incoherent articles I've seen here in awhile. I tried tracking through the arguments but kept finding that it repeatedly tried to prove an assumption by making that same assumption and went around in circles.

The Declaration of Independence refers to "The Laws of Nature and Nature's God" but also to the "Creator," as well as "appealing to the Supreme Judge of the world," and "with a firm reliance on the Protection of Divine Providence."
Humane Laws are measures in respect of Men, whose actions they must direct, howbeit such measures they are as have also their higher Rules to be measured by, which Rules are two, the Law of God, and the Law of Nature; so that Laws Humane must be made according to the general Laws of Nature, and without contradiction to any positive Law of Scripture, otherwise they are ill made. - John Locke, Two Treatises on Government
The Constitution did not forbid the establishment of state religions. The first amendment protected state establishments from encroachment by the establishment of a national religion. Many states had established churches after the ratification of the Constitution. Only after the Civil War and the passage of the fourteenth amendment was the Bill of Rights applied to the state governments.
