One of the more dense focal points of the argument against an originally Christian United States is that there was a severe wanting of true Biblical Christianity; a wanting which started during the founding of America. This is especially pervasive as they moved past the founding and into the Second Great Awakening. Fea describes the Second Great Awakening as so:
Humans were no longer…waiting passively for a sovereign and distant God who…offered select individuals the gift of eternal life. Instead, ordinary American citizens took an active role in their own salvation…the new theology empowered individuals to decide their own religious fate by accepting or rejecting the gospel message.
In this philosophy and theology, Americans became their own saviors. They were in charge of saving themselves; whether or not God wanted to save them did not matter. The problem here is that this was not and is not Christianity; this is moralism. The implicit idea of this theology is that humans can be good enough to determine if they may enter heaven or not. In other words, this theology is centered on the idea of self-salvation.
The Second Great Awakening was a force driven by its teachers and preachers. Many of these “Christian” teachers, such as Theodore Dwight Woosley, proclaimed that the majority of Americans believed in Jesus Christ and the Gospel. This pervasive assumption led to evangelists such as Billy Sunday that would take the assumption even further and say, “Christianity and Patriotism are synonymous terms…”. This absurd assumption projected Christianity onto Americans and inspired a self-fulfilling prophecy across the nation. This notion encouraged Americans to think, “I love this country; therefore, I am a Christian. God bless America!”
This is just not how Biblical Christianity functions; this is American nationalism. Mercy Otis Warren was another teacher who did not fight for Biblical Christianity but rather fought for this sense of nationalism. She is quoted as saying “religious and moral character of Americans yet stands on a higher grade of excellence and purity than that of most of other nations.” There was an implicit sense of arrogance in the fact that the people Ms. Warren knew were better than the people she had heard about in other nations. A true Christian would see Romans 3:23 and acknowledge the equal depravity of all mankind. The practicing Biblical Christian was the exception in this revival, not the rule.
If the United States was founded and purposed in Christianity, then America would look vastly different than it did and does. If the founders of the United States intended for the nation to be attached to a specific religion, then they all would have had at least moderately uniform thought processes on that matter. The part of America that gives people hope – domestically and internationally – is that basic American tenet of freedom and the ability to believe what one wants to believe without ridicule and persecution. The United States was not founded and purposed in any specific religion; rather, it was founded and purposed in freedom – all encompassing freedom.
