Why is there this constant battle about the US being a Christian nation...?

You're quite right, supporting slavery clearly proves they were christians.

The founding fathers were against the existence of a state religion. Many of them, or their families, had come to America to seek religious freedom. They were not all Christians and the ones who were Christians belonged to branches of Christianity which had bitterly and often violently opposed each other in Europe. The United States of America has never been a Christian nation and was never intended to be. Certain aspects of certain Christian ideal have shaped us, for example the idea of hard work in order be successful in life comes from the Calvinist Puritans. I was not aware that Christians put the Constitution on a pedestal, but whatever an American's faith the Constitution does deserve to be elevated, respected and revered because it is our greates national document and is perhaps the greatest document ever created by the human race.

We were never formally declared to be a Christian nation. That statement only applied because there once was a time when most of our citizens were Christians. The evidence of our nation's Christian heritage is overwhelming. The proof of our founder's religious beliefs is incontrovertible. You can hardly take a step in Washington DC and not run into monuments and landmarks that preserve that very idea.

Even though the majority of our founders were Christians, they worked hard to avoid establishing a theocracy. But at the same time, they knew that our form of democracy would only work with a free and moral people.

The battle is this...

There is an atheistic movement afoot that is seeking to rewrite our history and to rid the nation of its Christian beginnings. They can't stomach the historic references to God and The Bible, and they would like nothing more than to purge them from our existence. But they're meeting some considerable resistance.

Most christians don't put the Constitution on a pedestal. In fact christians hate the Constitution because it keeps their illogical thinking at bay. Christians like the Declaration of Independence because the word "Creator" is used.

It isn't even a governing document, but what can you do?

No, a christian's sin does not change the truth of God, or the truth about why we came to this country and on what principles we relied for guidance. There is no such thing as a christian who lives in this world without sin. When you go to the store for meat, and they sell you some that is bad, do you stop shopping there? Do you stop eating because you ate some bad meat? I do not expect you to believe, even if you could look at a man and know for certain that he was a perfect man...because the only perfect, sinless man ever born was killed because He told the truth, and man would not hear it.

Christians don't put the constitution on a pedestal. We just believe the historical facts surrounding how this country began as one nation, under God.

The constitution is a great document because it is alive (figuratively). I attribute it quite a bit of value, as close to sacred as you can get without believing in magic and gods and unicorns.

It is designed to become more perfect and to come from the people. In that sense it is a very humanist document. And in general, the constitution and its interpretation does trend towards becoming better and better.

OUr founding fathers were Diests not Christian or Atheist. But just beacause our founding fathers were or were not something does not change the fact that the majority of the US population is Christian!

It also does not change the fact that all the presidents in history were Christian, or that we still swear on the bible, or that before the Congress starts their meeting they always pray, or how "In God we Trust" is on every $ bill, and in the pledge.

We might have seperation of church and state(which I agree with) but that does not change the fact that we are still mostly a Christian Nation!

If you read back in history, southern Baptist did a lot of the pressing on congress for wording on money,

President Eisenhower changed the one nation under God in the pledge of a legends. Burn a witch save

a Christian is the continuance of delusional thinkers and their idiocy. Money, Power and Greed.

Some were Christian, but not all of them.

This site here that gives good info regarding the US being founded as a Christian nation. (Not)

Because the Christian-industrial complex wants to rebuild the US in its vision so by making the US a 'Christian nation' they can start to marginalize other religions and push their beliefs into government.
