Back into context of the Church and state debate. This history shows that government and Christianity did not mix well. So, so far we have seen God isn't happy with government. Jesus had issues with the government, as did his followers including disciples.
What was the prevailing mindset of pre revolution and post revolution America? Was the religious experience one of Christian unity? Or was it troubled, one that would lead the drafters of the constitution to want a wall of separation between government and all religious beliefs, even the belief of no God at all?
No God at all? Atheism wasn't a widely accepted belief until the 19 century (1 ). So the founding fathers might not seriously considered it. They would have considered past experiences with intermingling of Church and state and religious liberty.
Roman Catholics experienced disenfranchisement in the American colonies. In News York and Maryland people who were suspect of having "popish beliefs" were required to take oaths. In New Hampshire which was immediately repealed required freemen to be Protestants (2 ).

Some American Colonist seemed more willing to support religious freedom. Such as Virginias bill for establishing religious freedom (10 ).
During the constitutional convention in 1787 early drafts of the constitution Rejected religious qualifications to hold public office Charles Pinckney III of South Carolina proposed and it was unanimously adopted without debate that "no religious test shall ever be required as a qualification to any office or public trust under the authority of the U.

During debates and drafts of the first amendment the subject of protecting religious sects, denominations, groups, or societies. This also included protecting the right to worship, property, and practice these religion. since no religious ideology was excluded it can be derived that all religious Ideologies are included, including the belief in No God at all(13 ).

A peace treaty with the North African government of Tripoli that was approved by congress, article 11 of this treaty said Article 11 read, "As the government of the United States of America is not founded in any sense on the Christian religion -- as it has in itself no character of enmity against the laws, religion or tranquility of Musselmen [Muslims] -- and as the said states have never entered into any war or act of hostility against any Mahometan nation, it is declared by the parties, that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries." (14 ).
