Not very often. In fact, almost never. (Scrupulously avoiding the ad hominem goes a long way here.)
So when I see one, I pay attention. From the following post entitled, Three Misuses of the American Founding & Religion For Political Purposes, commenter Kari writes:
Some of you who doubt the christianity of our forefathers should actually read some historical documents with quotes by them, nearly all of them not only believed in but worshipped Jehovah God and were Christians who definetely [sic] believed in Jesus Christ! I am so tired of everyone trying to change history and say that our forefathers really weren't Christians. IT IS IN HISTORICAL DOCUMENTS...READ IT!!! Stop living in denial and read for yourself. Why do you think there were so many references to God and the 10 commandments made by these men. Did Christians falsify things to our advantage? I think not. Our nation used to be a Christian nation, that was the only way that a small group of colonists was able to win their independence from England who was a SUPERPOWER!! These men prayed daily for God to be with them during this endeavor and he was because they worshipped him and believed in his word...our whole nation did.
It is a shame that as Americans our true history is being removed from history books and warped and twisted by heathens who do not believe in God or His divine words. It should be a requirement that all judges(especially supreme court), lawyers and politicians read all of our historical documents that set precendence [sic] in the forming of the laws of our once great country and be forced to follow them.
People like you sicken me for you are warping history to suit yourself!
Well I think this is directed towards me, so I will answer.
1) Kari never touched one point I made; I would appreciate if she told me where in my post I specifically went wrong.
2) If you are "sickened" by what I write, I cannot apologize because because I have done nothing wrong. I have only recited facts and logic (and admittedly my understanding thereof which may be subject to debate). Perhaps the facts of history, not the myths that you were taught by Christian Nationalist history revisionists "sicken" you.
3) Jehovah God, Christians, Jesus Christ, Historical Documents and Ten Commandments.
a) From my meticulous study of the primary sources, I admit a strong majority believed in "Providence" and, as part of "Christendom" thought of themselves as "Christians" in some sense.
b) However -- and she can correct me if I am wrong -- that's not enough to be a "Christian" and believer in "Jehovah" as the "Christian Nationalists" articulate the concept.
c) Alternatively, some friends of mine, very generous in their ecumenicism, argue any kind of connection to belief in an active Providence equals Jehovah worship. For scriptural support, think of Acts 17, where St. Paul encountered seemingly pagan monotheistic Greeks who worshipped the God of the Bible without consciously knowing they did.
The key American Founders (Washington, Jefferson, and Madison, specifically) believed UNCONVERTED Native Americans who worshipped the monotheistic "Great Spirit" believed in the same God Jews and Christians did. I guess Jehovah and the unconverted Natives' "Great Spirit" God are one and the same. Likewise Allah is Jehovah, even if the Muslims, like those Native Americans, get some of the details wrong.
But it's that line of thought -- that Jews, Christians, theological unitarians (Trinity deniers), Mormons, Jehovah's Witnesses, Muslims -- all worship the same God, the true God (Jehovah). I know Mormons and JWs didn't exist during the American Founding. Though the Swedenborgs, who did, make for a good substitute.
I don't see "Kari" as arguing from this corner; correct me if I am wrong.
d) Re the historical documents: You may be able to find some more general God words in the US Constitution, Declaration of Independence and Federalist Papers. But you don't see "Jehovah" or "Jesus Christ" in them. The US Constitution does use the conventional "In the Year of Our Lord" (i.e., AD on our currency) for dating purposing. Trying to make "God" out of that shows how nominally the US Constitution invokes God. (In other words, if the US Constitution is not "Godless," it is "Godly" in the most nominal sense only.)
e) The Ten Commandments: What are you talking about? Where did George Washington specifically invoke the Ten Commandments? John Adams and Thomas Jefferson both DOUBTED that we had the correct version of the Ten Commandments? What about James Madison? A supposed quotation of his on the Ten Commandments circulated (in large part to the efforts of David Barton who is still trying to live this down) only later to have been debunked.
I think Kari's note is important because it illustrates how corrupt the rot is among the home schooled "Christian Americanists." David Barton et al. may not be so stupid to themselves make such grievous errors. But they give winks and nods to the kind of errors this commenter makes.
