... I want to emphasize from the outset that I believe that we have far more critical issues... the hungry children I saw in West Virginia, the old people who cannot pay their doctors bills, the families forced to give up their farms -- an America with too many slums, with too few schools, and too late to the ... outer space. These are the real issues ... And they are not religious issues -- for war and hunger and ignorance and despair know no religious barrier.
... it is apparently necessary for me to state once again -- not what kind of church I believe in, for that should be important only to me -- but what kind of America I believe in.
I believe in an America where the separation of church and state is absolute; where no Catholic prelate would tell the President -- should he be Catholic -- how to act, and no Protestant minister would tell his parishioners for whom to vote; where no church or church school is granted any public funds or political preference, and where no man is denied public office merely because his religion differs from the President who might appoint him, or the people who might elect him.
I believe in an America that is officially neither Catholic, Protestant nor Jewish; where no public official either requests or accept instructions on public policy from the Pope, the National Council of Churches or any other ecclesiastical source; where no religious body seeks to impose its will directly or indirectly upon the general populace or the public acts of its officials, and where religious liberty is so indivisible that an act against one church is treated as an act against all.
... I believe in an America where religious intolerance will someday end, where all men and all churches are treated as equals, where every man has the same right to attend or not to attend the church of his choice...
That is the kind of America in which I believe. And it represents the kind of Presidency in which I believe, a great office that must be neither humbled by making it the instrument of any religious group nor tarnished by arbitrarily withholding it -- its occupancy from the members of any one religious group. I believe in a President whose views on religion are his own private affair, neither imposed upon him by the nation, nor imposed by the nation upon him as a condition to holding that office.
I would not look with favor upon a President working to subvert the first amendment's guarantees of religious liberty; nor would our system of checks and balances permit him to do so. And neither do I look with favor upon those who would work to subvert Article VI of the Constitution by requiring a religious test, even by indirection. For if they disagree with that safeguard, they should be openly working to repeal it.
I want a Chief Executive whose public acts are responsible to all and obligated to none, who can attend any ceremony, service, or dinner his office may appropriately require of him to fulfill; and whose fulfillment of his Presidential office is not limited or conditioned by any religious oath, ritual, or obligation.
This is the kind of America I believe in ... I do not speak for my church on public matters; and the church does not speak for me. Whatever issue may come before me as President, if I should be elected, on birth control, divorce, censorship, gambling or any other subject, I will make my decision in accordance with these views -- in accordance with what my conscience tells me to be in the national interest, and without regard to outside religious pressure or dictates. And no power or threat of punishment could cause me to decide otherwise.
But if the time should ever come... 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.
