Referencing people whom continue to deny the religious foundation of the great nation of the United States of America, I believe people are entitled to their own opinion but not to their selective and fabricated "facts". I digress at this time to say it use to be said that "what you do not know won't hurt you" but I say at this time its "the things you know and believe as fact but are not, these are the things that will hurt you and everyone else ". The facts are 36 of the 55 framers of the constitution in Philadelphia 1787 were members of the continental or Confederation congress - except for 5 exceptions; they were orthodox members of one of the established Christian communities. For the 39 of the 55 framers of the constitution who signed the constitution their religious membership are as follows:

 Congregationalist - 5
 Deist - 4 
  Episcopal - 15
 Lutheran - 1
 Methodist - 2
 Presbyterian - 7
 Quaker - 3
 Roman Catholic - 2

The 4 Deist that signed were the only Deists of the 55 framers of the Constitution! The colonists were familiar with deist thinking. But deism never gained a strong foothold in America. The first Great Awakening, the religious revival of the 1740s, was partially responsible for cutting short the spread of deism. In many states at the time of the Constitutional Convention, confessed deists were not allowed to hold public office. Deism was generally held in low esteem, as such laws indicate. Additionally, Deism as practiced at the time of America's founding was far different from what we find in our country today, and it certainly was not atheism. In addition, somehow the Supreme Court deemed in the 1900's that the constitution deemed there was a "separation of church and state" by a letter Thomas Jefferson (taken out of content) wrote to some church but what is ironic about that is Thomas Jefferson was not a signer of the Constitution, writer, or a participate at the Constitutional Convention. Thomas Jefferson like Samuel Adams was out of the country so why was a subsequent letter written by Jefferson so germane to the Supreme Court. In addition, the 1797 Treaty of Tripoli was a joke and taken out of content. Why was this so called treaty invented was to pay bribes to pirates. The pirates of (Muslims of Tripoli) the Barbary Coast in general and of Tripoli (in what is now called Libya) in particular were destroying U.S. shipping and holding as prisoners U.S. seamen in the 1790s. It was a serious problem and a series of negotiators were sent to try to put together an agreement to improve it. The Treaty was written by Barlow a friend of Thomas Paine both non believers in God and in the  version of the treaty read and signed by the representatives of Tripoli the famous words were not included (they are not present, as was discovered in about 1930, in the surviving Arabic version). For whatever reason certain words were put into that treaty no one knows but it is very likely that Muslims of Tripoli were in fear of a religious war from the U.S and required it in the so called treaty since they had the upper hand! During the first two presidents (Washington and Adams) we paid bribes to these pirates because America had no Navy! The treaty remained in effect for only four years, replaced, after more war with Tripoli, with another treaty that does not have the famous words included. One or two later treaties even allude to the Trinity. President Jefferson when he became President established a navy and went to war with Tripoli because the bribery and privacy had to stop and Jefferson whom had previously during Washington Administration tried to negotiate with the Muslims of Tripoli stated they could not be trusted and/or reasoned with. And from this episode came a song you remember "from the halls  ..... to the shores of Tripoli!" And if the Constitution is entirely secular then why does it say before all those signatures " in the year of our Lord" what Lord do you think these religious framers were talking about? And for those who think that the religion of America is up for grabs well read the Koran and see how different America will be under that influence!
