The religious roots of this country were extremely weak. They had to add a religious element to it because otherwise they couldn't justify the American Revolution at all. The King of England wasn't just a civil ruler; he was also the head of the Church of England.
That's why religion had almost no role -- other than legal protection against the establishment of an official national religion -- in the founding of the country.
In more cynical moments I wonder if colonial faith was everything it was cracked up to be.
Nonetheless there were bright flashes of faith in the founding days.
*The religious roots of this country were extremely weak.”
I’m astounded at that statement. Had it not been for religion, of numerous flavors, from New England meeting houses in 1600 to the backwoods of NC/TN 50 years later where Lutherans and Baptists built their meeting houses, there would have been no Great Awakening, no challenge to the divine right of a king, no revolution at all. And certainly no concept of Inalienable Rights granted from God.

That depends on what you mean by "the founding of the country."
And the reason religion may not have played a role in writing the Constitution is that there were several different, strong, conflicting religious denominations and traditions.
The Founders had a way of not talking about things that could be divisive.
Alexis de Toqueville would have disagreed with you. Who is the “they” you are referring to?
Are you even aware of Washington’s warning regarding factions and the “Man on Horseback”...on how he viewed “Religion and Morality as being the Twin Props upon which our freedoms rested”? You need to study a little more...I don’t think you are ready for prime time!
