Well, religious nutbag Mike Huckabee claimed that most of the signers of the declaration of were clergy, which means that according according to Republican math, 1 out of 56 equals most. John Witherspoon* was the only active clergymen. The right wing Heritage Foundation claims that there were two signers who were former clergymen, and Adherents.com said four signers of the declaration were current or former full-time preachers.
George Washington was probably a deist, who refused communion. All indications are that he was more involved with Masonic theology (God as creator and now not involved on a day to day basis with the world). He rarely if ever, referred to Jesus.
John Adams became a Unitarian, rejecting fundamental doctrines of conventional Christianity, such as the Trinity and the divinity of Jesus
In his, “A Defence of the Constitutions of Government of the United States of America” [1787-1788], John Adams wrote:
“The United States of America have exhibited, perhaps, the first example of governments erected on the simple principles of nature; and if men are now sufficiently enlightened to disabuse themselves of artifice, imposture, hypocrisy, and superstition, they will consider this event as an era in their history. Although the detail of the formation of the American governments is at present little known or regarded either in Europe or in America, it may hereafter become an object of curiosity. It will never be pretended that any persons employed in that service had interviews with the gods, or were in any degree under the influence of Heaven, more than those at work upon ships or houses, or laboring in merchandise or agriculture; it will forever be acknowledged that these governments were contrived merely by the use of reason and the senses.
“. . . Thirteen governments [of the original states] thus founded on the natural authority of the people alone, without a pretence of miracle or mystery, and which are destined to spread over the northern part of that whole quarter of the globe, are a great point gained in favor of the rights of mankind.”
Jefferson believed in materialism, reason, and science. He never admitted to any religion but his own. In a letter to Ezra Stiles Ely, 25 June 1819, he wrote, “You say you are a Calvinist. I am not. I am of a sect by myself, as far as I know.”
James Madison found established religion pernicious.
In 1785, Madison wrote in his Memorial and Remonstrance against Religious Assessments:
“During almost fifteen centuries has the legal establishment of Christianity been on trial. What have been its fruits? More or less in all places, pride and indolence in the Clergy, ignorance and servility in the laity; in both, superstition, bigotry and persecution.”
“What influence, in fact, have ecclesiastical establishments had on society? In some instances they have been seen to erect a spiritual tyranny on the ruins of the civil authority; on many instances they have been seen upholding the thrones of political tyranny; in no instance have they been the guardians of the liberties of the people. Rulers who wish to subvert the public liberty may have found an established clergy convenient auxiliaries. A just government, instituted to secure and perpetuate it, needs them not.”
Then there is the treaty of Tripoli, ratified in 1979
As the Government of the United States of America is not in any sense founded on the Christian religion; as it has in itself no character of enmity against the laws, religion, or tranquillity, of Musselmen†; and as the said States never have entered into any war or act of hostility against any Mehomitan 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.”
What is clear is that however spiritual the founding fathers were, they were disdainful of organized religion, considering it to be ignorant superstition.
