The third criteria for a nation to be considered Christian, as stated in a prior article, would be that the constitution and resulting government contain a built in assumption that the citizenry is Christian. There is a subtle difference between this criteria and the first. The first criteria required that there be accepted laws that are by definition Christian in nature. To determine the validity of the third criteria we would need to establish that the constitution in general will not work unless the United States was a Christian nation. For example in Iran the laws and government are so intertwined with the Muslim religious establishment, that the government could only function where the population is Muslim. That is not to say that accommodations are not made for other religions. But these accommodations are exceptions to the general precepts of the nation of Iran .
So, does our constitution have a built in assumption of a Christian citizenry? It would probably be safe to say that the founding fathers acknowledged the difficulties that would arise in a nation of free people without religious convictions.
"We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge, or gallantry, would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other." John Adams to Massachusetts militia 1798
There is no doubt that our nation has gone through cycles of prosperity and peace, as well as cycles of economic depression and civil war. It would seem that much of the tragedy that is part of our history can be traced back to “Avarice, ambition, revenge, or gallantry”. In general, a religion that censures these undesirable qualities would better suit a nation that desires freedom and prosperity. Are these censures unique to Christianity? No, there are many religions that have a good strong moral code within their teachings. Is it likely that the colonial citizenry would have ever adopted one or more of these religions to where it became the predominant religion of the country. No, in fact the only two non-Christian religions that ever gained the slightest foothold in colonial America were witchcraft and voodoo. There were, of course Jews scattered throughout the colonies, mostly in the south. But given their small numbers, it was unlikely that Judaism would ever become the predominant religion of the United States .
Are there examples of other countries with a similar form of government, that are not Christian that have a long history of freedom and prosperity? No, throughout the world, the only nations that have formed a constitutional democratic form of government that has lasted more than 30 years have been Christian nations.
Does being a Christian nation guarantee democracy will hold? No, Germany and Italy are examples of democracies that within their constitutions fell to fascism.
Our nation and its political structure do require the people to be moral people. We see where it unravels when that morality is violated. That morality does not have to be labeled as Christian morality. However, Christianity and the moral teaching of its founder, have the best chance of guiding people in this country to make choices and live lives that nourish freedom and prosperity.
