"And no power or threat of punishment could cause me to decide otherwise. But if the time should ever come -- and I do not concede any conflict to be remotely possible -- when my office would require me to either violate my conscience or violate the national interest, then I would resign the office; and I hope any conscientious public servant would do likewise. But I do not intend to apologize for these views to my critics of either Catholic or Protestant faith; nor do I intend to disavow either my views or my church in order to win this election. If I should lose on the real issues, I shall return to my seat in the Senate, satisfied that I'd tried my best and was fairly judged. But if this election is decided on the basis that 40 million Americans lost their chance of being President on the day they were baptized, then it is the whole nation that will be the loser, in the eyes of Catholics and non-Catholics around the world, in the eyes of history, and in the eyes of our own people. But if, on the other hand, I should win this election, then I shall devote every effort of mind and spirit to fulfilling the oath of the Presidency -- practically identical, I might add, with the oath I have taken for 14 years in the Congress. For without reservation, I can, solemnly swear 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 -- so help me God."
This is John F. Kennedy's address to the Greater Houston Ministerial Association.
