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 parishoners 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.
