I also discovered, to my pleasant surprise that many of the best scholars who debunk the “Christian America” idea are devout traditional Christians, many of whom are concerned with keeping their biblical faith pure from corrupt, non-biblical influences (i.e., “Americanism” or the theology of “Founding era republicanism” which is not biblical, but often presented itself under theological auspices, i.e., “the laws of Nature and Nature’s God,” which many conservative Christians today confuse with “biblical” ideas).
Notable traditional Christian scholars who refute the "Christian America" thesis include Mark Noll, Nathan Hatch, George Marsden, Robert Kraynak, Gary Scott Smith, Gary North, and Gregg Frazer (see more on him below), all of whom possess PhDs from prestigious universities and heavyweights like Noll, Hatch and Marsden are arguably among the most well-respected scholars of American religious history period.
As noted, I saw something wrong with the secular talking points as well. Regarding the debate over whether the Founders were Deist v. Christian, I noticed there was some middle ground between the two systems in which many of America's Founders seemed to believe. They may have been "Christians," but weren't orthodox Trinitarian Christians. Or they may have been "Deists," but they believed in an active personal God which contradicts a fundamental tenet of Deism. They seemed to be theological unitarians or otherwise not identifiably Trinitarian, but didn't belong to Unitarian Churches or "societies" which really didn't exist in the mid-late 18th Century (a few got started in the 1780s, but you could count them on one hand; lots of preachers in the New England Congregational Churches, since the mid 18th Century, were "unitarians," but those Churches didn't become "Unitarian" until around the turn of the 19th Century). In the 18th Century, unitarianism was a personal theology, not a Church.
So, I discovered, the key Founders weren't really strict Deist or orthodox Christians, but somewhere in between. Around the time this lightbulb went off, fortuitously or perhaps Providentially, the Claremont Institute, whose website I had been reading regularly, published an article by Gregg Frazer which perfectly articulated what I saw as a needed new paradigm in the debate. I subsequently purchased his PhD thesis from Claremont Graduate University, parts of which I have read over many times. And, daily, I have expanded my knowledge pouring through the primary sources, reading dozens of books on the matter (reviewing one of them for First Things Magazine; kind of odd in that I'm not a traditionalist Catholic conservative, but a soft secular libertarian; but when they asked me to write that "Briefly Noted" book review, I wasn't about to refuse a magazine that publishes Supreme Court Justices; plus I do greatly respect their high intellectual output even if I often disagree with their positions) and am still engaged in knowledge expansion and mastering the primary sources (with the help of neat tools like search engines and googlebooks) on a daily basis, as an avocation.
When I make arguments and discuss my research on the new paradigm and use the term "theistic rationalist" to describe the creed of America's key Founders, I often cite Dr. Frazer by name. And I do that simply because I want make sure I give credit where credit is due and properly cite my sources.
I also don't want folks to get the misimpression that Dr. Frazer and I necessarily agree on issues other than in the specific sense that I endorse his work. Don't think because I throw his name around that he is a "soft-secularist" and a political libertarian like me; he is not. From what I can tell, he is more of a meat and potatoes religious conservative. And in his commentaries, he stresses his traditional conservative worldview and approach to constitutional interpretation more so than I do when I cite him. So perhaps, for the sake of perspective, I should reproduce one of his brief commentaries replying to common "secular left" talking points, in a local California news outlet:
Scott Holleran (Viewpoint, Feb. 11) overstates his case and misstates history. While the founders were not, as a rule, born-again Christians, they were religious and thought religion very important to the welfare of the nation. None of the founders doubted the existence of God and none was ``openly hostile'' to religion.
John Adams denied America was a Christian nation, but he also said: ``Our Constitution was made only for a moral and religious people.'' James Madison, author of the Establishment Clause, said what it meant: ``that Congress should not establish a religion, and enforce the legal observation of it by law.'' That's it. The Supreme Court in 1947 created the ``separation principle,'' not the founders.
