There is no divergence. I have argued that James Madison and Thomas Jefferson were visionary secularists and that they launched what was a historic, if ultimately faltering, and kind of feeble secularization project. That is true. Other notable Americans of the revolutionary era were acutely Protestant. Patrick Henry and John Jay, for example. They were deeply religious and wanted the US to be so too. So was Timothy Dwight. So were many, many others of the revolutionary generation. Most people probably wanted the US to be a devout country. But there was no agreement on what that meant. The range of positions was broad, very broad.
It is crucial however to understand that “Christian nation” has always been a term of bigotry and exclusion. First, when Americans of the 18th and 19th century used the term they were saying Catholics were not Christians. Then--as now--most Christians in the world were Catholic. It makes no sense to call a country hostile to most of the world’s Christians a “Christian nation.”
