There is no significant example in history, before our time, of a society successfully maintaining moral life without the aid of religion.
And the consequences to our country?, Well, John Adams pointed it out:
“Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.”
Our system of government cannot survive without a Judeo-Christian society underpinning it. Kicking the underpinnings out, will collapse it.
