I've shown you, clear as a bell, John Adams flatly stating that our government was...explicitly...not founded on Christianity.
First of all, it should be noted that the specific statement you quoted is not found in the Arabic translation of the Treaty. At all. There is no article 11 in the Arabic where that aspect of the treaty was quoted. The English version of that article in the treaty was not "discovered" until 1930. That treaty was reworked 8 years later and article 11 was no longer part of it.
But that aside, and let us assert that Article 11 is in fact the exact and originally agreed language of the signed treaty sent with JL Cathcart to Tripoli - Why exactly did Adams write that statement to the Dey of Algiers and the Sultan of Tripoli? Was it because Adams was making a manifesto of our origins to the American people?
Or because they were desperate to get a treaty with the Mohammedan barbary regimes to avoid war so soon after our own nation was barely on it's feet? You know, the Barbary coast regimes that considered any Western nation's ships that did not pay tribute via treaty to be fair game for piracy, plunder and crews sold into slavery?
At this point, the argument is pointless...
It most likely is.
you are unable to accept the obvious preponderance of evidence demonstrating just how deeply determined the FF's were to keep religion...even Christianity...out of government.
Well, considering that murder, false witness, adultery, abomination, coveting, stealing, greed and envy are what constitutes government in Washington DC these days, keeping religion out of government and it's public servants and institutions separated from the biblical religion has worked wonderfully for our culture and nation.
Pat yourself on the back for the fruits of your desired historical revisionism are self evident and all around us in this society today.
