Nowhere had the line between rituals of church and state been more blurred in the post-1945 years than in the way in which the presidential speech making capitalized on the forms of Protestant preaching. The resemblance ran much deeper than the references to God sprinkled heavily throughout presidential speeches or the benedictory forms with which they closed. Adaptation of sermonic authority and sermonic cadence was integral to the high presidential style. The people gathered together–preacher and congregation–to hear their civic creed reaffirmed.
