In light of the systematized Christian system described by Calvin, the founding fathers had an excellent blueprint to establish a nation. The founders clearly made some mistakes in forming this country; one being the way they setup freedom of conscience. ... Unchecked belief in idolatry like the founders allowed in this country was suicide and today is the proof of their error.
Note: Links to Madison's Notes on the Memorial and Remonstrance added by me.
One of the main founders was James Madison. His understanding of religion and the state was different and he rejected Reformation principles on the subject. Madison's Notes preparing his Memorial and Remonstrance is filled with incoherency.
An unbeliever could make the case Madison was no Christian at all with perfidious statements like these. Another founding father, John Adams was a definite Unitarian, who denied parts of the bible, and was ignorant about the canon of scripture. Today, Adams would be a liberal bigot, which is most of the [D]emocratic party. However, for Madison to even bring these ideas up is troubling. At least Bishop Meade believed he was a real Christian. I'm not entirely convinced to take his word for it.
