I affirm this message

Before he enter on the Execution of his Office, he shall take the following Oath or Affirmation:—"I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."

New Zealand PM, who looks like a promising young star, took the affirmation route. Our own "affirmation" option was largely put in place for those who did believe in God, but per Jesus, were wary of oaths. "Oath" implies "so help me God," so that is a bit redundant.
