Page "Civil religion" Paragraph 35

These two conceptions ( sociological and political ) of civil religion substantially overlap.

In Britain, where church and state are constitutionally joined, the monarch's coronation is an elaborate religious rite celebrated by the Archbishop of Canterbury.

In France, secular ceremonies are separated from religious observances to a greater degree than in most countries.

In the United States of America, a president being inaugurated is told by the Constitution to choose between saying " I do solemnly swear ..." ( customarily followed by " so help me God ", although those words are not Constitutionally required ) and saying " I do solemnly affirm ..." ( in which latter case no mention of God would be expected ).
