There has been quite the uptick regarding the topic because of fears that America has lost its greatness. "America's Destiny Must Be Freedom," is a commentary I penned in June related to that fear, as well as an overview of America's freedom narrative. I also hosted an Acton on Tap on American Exceptionalism last August. I addressed the history of the theological roots, the different strains of thought related to American Exceptionalism, and the debate today.
After you listen to the podcast, check out the links below for additional resources related to American Exceptionalism. The sources offer a diversity of thought on the subject.
