I found this article, 5 Reasons America Is Not—And Has Never Been—A Christian Nation, and I wanted to speak on this. This is a classic case on how someone can be technically correct, yet totally wrong.
I will agree, that the federal government is purposely neutral concerning religion in the Constitution. James Madison, the man who wrote the initial draft of the Constitution, never wrote about his religious views. Our Founding Fathers wanted to avoid at all costs any hint of an "official religion." They broke away from England who had a state-approved religion (the Church of England), the head of that church was King George III himself.
Thus, when the Constitution was written, it specifically stays silent on any particular religion, even including in Article 6, Clause 3, "... but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States." The first words of the First Amendment also specifically states, "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof;"
With all of that said, the author is correct. Technically.
Here's where the author gets it wrong: The men of that day by and large had a strong moral sense. They and the society they lived in had a strong moral code, with clear boundaries as what was right and wrong. No matter a mans religion, they shared a societal construct that could be traced back through the Magna Carta, the Ten Commandments, all the way back to the Code of Hammurabi. In the time of the Colonies, a mans word was his bond. A man who broke his word was usually ruined, and the punishment would run from derision by the entire local populace, to being tarred and feathered and/or being ridden out of town on a rail.
He had a strong moral compass that was instilled in him at a young age, based on what is known as "Judeo-Christian" beliefs. These were based on the Ten Commandments. Since the 60's, when the "do your own thing" idea came out, our societal rules have fallen by the wayside. The concept of "you can't judge me" has also come into vogue. The structure of our society is unraveling before our eyes. We have been slowly conditioned to "let the government do it" as far as punishing those who break the rules.
The result? A country where you commit an average of three felonies a day. A country overburdened with thousands upon thousands of laws, rules, regulations and policies. It is nigh on impossible to go on about your day and not break some law. The only question when you are caught breaking a law is, how much effort does the government want to put into investigating you and your subsequent prosecution. History is replete with major arrests and prosecutions that started with a minor traffic violation. Timothy McVeigh was pulled over for an expired license plate. And there is a thousand more examples.
The end result is we have no internal moral compass any more. We have become content to let others define our standards and morals. We defer to authority, and thus forge the very chains that will be used to enslave us. We need to stand up for what we know is right and against what we know is wrong. When someone tells us we have to stop doing something we are doing because "it might offend someone" we need to stand up and say, "I refuse to let my actions be dictated based on how someone else might feel."
