In 1967, Robert Bellah argued that America’s “founding myth”, what he called American civil religion, helps bind American society together by providing its citizens with a sense of origin, direction, and meaning. For evidence, Bellah primarily turned to the inaugural speeches of American presidents. This paper draws on semantic network analysis to empirically examine the inaugural addresses of Presidents Trump and Biden, looking for evidence of what some would consider aspects of American civil religion. As some believe American civil religion to be no more than a thinly veiled form of nationalism, it also considers the importance of words associated with nationalism. It finds that both Trump and Biden employed the language of nationalism and American civil religion in their respective addresses, and while it found no differences in their use of nationalist discourse, it did find that American civil religion figures more prominently in Biden’s address than in Trump’s.
