If our nation was founded as a Christian nation does not Christian specifically refer to Christ, Jesus Christ? So I assume there are many references to Jesus in the original documents. At least a single reference to Jesus in the founding document perhaps? One? Anywhere?
Names for the Judea-Christian God found in the Declaration of Independence:
Creator
Supreme Judge
divine Providence
But that's just the Declaration of Independence. In the context of societies built largely on the social and political theories of Puritanism and Covenant theology, first in New England, then in the middle colonies, then in the southern colonies, the principles of our early Christian society are the principles referred to in the DoI.
So
Creator was code for: Jesus
Supreme Judge was code for: Jesus
divine Providence was code for, you guessed it: Jesus
And Christian "principles" was how our government was shaped? Don't read much, do you?
If you read much (do you?), you can see for yourself that Abraham called God the
Supreme Judge. It's a term common in Rabbinic literature. And
divine Providence is also a name for Him common in Jewish thought and also in Christian theology, including Calvinism (covenant theology).
And do you think government is not based in principle? Governments just appear out of the sky?
Seriously, read some.
