The founding fathers wanted a lot of things, Jefferson wanted routine revolution against the government (I happen to think this one should be done), many wanted laws to naturally expire after a certain number of years (in theory a good idea, but in practice would probably produce omnibills with lots of hidden laws). But this is our Republic, and the nature of what We the People want and desire changes. During the heyday of absolute Christian dominance, yeah there were what you said. But what's acceptable and what's not changes with time. The founders owned slaves, so unambiguously claiming that because the founders did it makes it right isn't a complete argument. I happen to like a lot of what the founders said, especially the anti-federalists (whom oddly enough were federalists in the true sense of the word). But what's political philosophy and what is public pressure/accepted norm are two different things. And the pressures and accepted norms change with the generations. Things aren't stagnate. Yes the founders did some of these things, they had religious holidays and evoked the name of gods in relation to politics. But that was then and this is now, the accepted norm isn't one of total and absolute Christian dominance anymore and the government, including the SCOTUS the body which currently has power to interpret the Constitution, has stated that it is no longer applicable.
