The United States was not founded as a Christian nation, because slavery was in the Constitution and Jesus was not. The people who said this, rather loudly and for quite a long time, were called the Covenanters [aka Reformed Presbyterians, Cameronians, Society People, Old Light/Old School, Anti-Burghers, Seceders, Associate Reformed Presbyterians, United Presbyterians, etc.]. Whereas today most religious conservatives insist that America’s Founders created a Christian nation, Covenanters were the most conservative Christians in early America, and they vehemently disagreed. . . . the most strident critique of America’s failure to be a Christian nation came from the right (Joseph S. Moore, Founding Sins: How a Group of Antislavery Radicals Fought to Put Christ into the Constitution, 1).
