Via CaseyOR, John F. Kennedy on September 12, 1960:
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 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 it. If they disagree with that safeguard, they should be out openly working to repeal it.
[. . ..] And in fact,this is the kind of America for which our forefathers died, when they fled here to escape religious test oaths that denied office to members of less favored churches; when they fought for the Constitution, the Bill of Rights and the Virginia Statute of Religious Freedom[. . . .]
[. . .] Whatever issue may come before me as president — 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 the national interest, and without regard to outside religious pressures or dictates. And no power or threat of punishment could cause me to decide otherwise.
[. . .] I ask you tonight to follow in that tradition, to judge me on the basis of my record of 14 years in Congress, on my declared stands against [. . .] unconstitutional aid to parochial schools [. . .] — [consider] the statement of the American Bishops in 1948, which strongly endorsed church-state separation, and which more nearly reflects the views of almost every American Catholic.
(Emphais supplied.) Today's Republicans and religious leaders have launched a culture war, and people like E.J. Dionne are applauding that war. Shame on them.
