> If America was not founded as a Cristian nation, why then are such a vast number of city names Cristian based?
Because most Americans are and have been Christian. Nevertheless, the Constitution is quite silent on the whole Christianity thing. The First Amenment stands in stark opposition to the First Commandment.
The US was not founded as a Christian nation, as an atheist nation, or as any type of nation WRT religion. It was founded as an Enlightened nation, with the government deriving it's power from the governed. The United States was founded with a reverence for Democracy, a pagan Greek concept originally; to see the Biblical view of Democracy, read Numbers 16: 2-49, where God wipes out 15,000 Israelites because 250 of them wanted democratic representation.
Founded on Christian principles and founded as a Christian nation are not the same thing.
Nobody said "Christian nation." The word was "principles," and that is undoubtedly correct.
Many of the colonies were founded on explicitly Christian grounds, however -- Massachusetts (Puritans), Pennsylvania (Quakers), Maryland (Catholic), Rhode Island (Non-conformist), and Connecticut (Puritan). The remaining colonies had very strong Church of England ties, and the Founders were all religious men.
The First Amendment Establishment clause was not anti-religious; indeed, it was precisely the opposite. The aforementioned colonies were founded as a means to escape the oppression of the state religion of England. Freedom to exercise Christian worship was the primary driver for putting the Establishment clause into the Constitution.
God spoke to the people through the prophet Samuel on the evils of monarchy and the tyranny of the State.
God condemned the rise of humanism, again represented by a totalitarian State, in the account of the Tower of Babel.
The spheres and offices of Priest and King were separate.
The people were part of the election of civil leaders in the Old Testament and we find checks and balances in the civil law regarding the State in the Old Testament.
Our Declaration of Independence explicitly finds our rights granted by and rooted in Not the State, nor a document, nor in the consent of the governed but in the Creator.
In the "godless" Constitution, above George Washington's signature is written, "In the Year of Our Lord." Whose Lord? The incarnate and virgin born, Jesus Christ. Given the times and popular sentiment (just look at the example of Enlightenment France - rights rooted in the State, granted to the people by an omnipotent State) the term, "Year of Our Lord" could have remained unused. That is was included is telling.
Enlightenment thought, with its latent humanism, bore its seed in the 20th Century under Hitler, Stalin, Mussolini, Mao, Pol Pot, etc.
We are not a Democracy. We are a Republic. And the Constitution requires each State to have a Republican form of Government.
The Founders did not think very highly of Democracy or Mob-ocracy. Here's what Madison, the father of the Constitution, thought of democracies: "Democracies have ever been spectacles of turbulence and contention; have ever been found incompatible with personal security, or the rights of property; and have, in general, been as short in their lives as they have been violent in their deaths."
As to your exegesis of Numbers 16:2-49. It may reflect a biblical view on democracy, but most clearly shows how God deals with revolt and rebellion. The Mob got what it deserved.
The Founders frowned on democracy. Read the Federalist Papers.
