Reddit mentions of The Religious Beliefs of America's Founders: Reason, Revelation, and Revolution (American Political Thought (University Press of Kansas))

I disagree with you.

The founding fathers were, by and large, deists. Notice the Declaration specifically names a "Creator." It doesn't mention the Christian god.

Since you mentioned Adams, he had a deep distrust of Roman Catholicism and signed the Treaty of Tripoli while in office, which includes the following: "As the Government of the United States of America is not, in any sense, founded on the Christian religion;"

Jefferson, Adams, Madison, Franklin, Paine, Hamilton, and even Washington were not mainstream Christians. Don't equate belief in god with Christianity. Billions of people are non-Christian and believe in god.

If you want to read more, here's a book written by an actual historian: http://www.amazon.com/Religious-Beliefs-Americas-Founders-Revelation/dp/0700620214/ref=asap_bc?ie=UTF8

Yet there are a ton of quotes attributed to them in both directions. You can not make the claim that the founding fathers were religious or atheistic based on quotes alone. There is an intresting book that covers the topic here.

The gist is a majority identified as religious, the books claims the leaders, Adams, Jefferson, Franklin, Wilson, Morris, Madison, Hamilton, and Washington, belived in theistic rationalism, which, as it sounds, is an attempt to rationlize religion.

Now calling the constitution a compromise, in the way you did, is a bit misleading. Granted compromise is the corner stone of democracy, yet it seems to me you are implying that the compromises are a bad thing. Thankfully, the compromise that is the first amendment allows us to have this little talk free of governmental regulations.
