The effort which resulted in effectively "erasing the American memory" (L. Cheney?) by removing from the nation's textbooks any ideas whose roots were in Judeo-Christian thought, under the guise of their own distorted interpretation of Jefferson, has been a most damaging tactic which enabled many other assaults on the Constitution's protections.
Recently, I have posted references to a Centennial Thanksgiving Sermon (1876 - Declaration of Independence) by Rev. Benjamin W. Arnett, delivered at the St. Paul A.M.E. Church in Urbana, Ohio. Already, at that date, he identified a movement whose leaders self-described as "liberals" had dedicated themselves to bringing about radical changes, which were listed in his Sermon. In a section titled, "The Danger to Our Country," Arnett listed the goals of that group. We can read that list and see that, in 2012, the goals have been achieved, for the most part.
Arnett's is a remarkable tracing of the history of nations, especially of American liberty, and should be read by all of us today. He was an Ohio Legislator and Minister and an obvious scholar. His theme was, "Righteousness Exalteth a Nation, but Sin is a Reproach to Any People." It is available at the Library of Congress, American Memory Section, "African-American Pamphlets from the Daniel A. P. Murray Collection," 1820-1920. Once on the site, click on "Read full text."
The roots of the move to take America off its firm foundations were laid early, and its enemies have worked on the dismantling by using self-described "intellectuals" as "useful idiots" in the destruction.
