A few Christian fundamentalists attempt to convince us to return to the Christianity of early America, yet according to the historian, Robert T. Handy, No more than 10 percent probably less of Americans in 1800 were members of congregations.
The Founding Fathers, also, rarely practiced Christian orthodoxy. Although they supported the free exercise of any religion, they understood the dangers of religion. Most of them believed in deism and attended Freemasonry lodges. According to John J. Robinson, Freemasonry had been a powerful force for religious freedom. Freemasons took seriously the principle that men should worship according to their own conscience. Masonry welcomed anyone from any religion or non-religion, as long as they believed in a Supreme Being. Washington, Franklin, Hancock, Hamilton, Lafayette, and many others accepted Freemasonry.
The Constitution reflects our founders views of a secular government, protecting the freedom of any belief or unbelief. The historian, Robert Middlekauff, observed, the idea that the Constitution expressed a moral view seems absurd. There were no genuine evangelicals in the Convention, and there were no heated declarations of Christian piety.
George Washington
Much of the myth of Washingtons alleged Christianity came from Mason Weems influential book, Life of Washington. The story of the cherry tree comes from this book and it has no historical basis. Weems, a Christian minister portrayed Washington as a devout Christian, yet Washingtons own diaries show that he rarely attended Church.
Washington revealed almost nothing to indicate his spiritual frame of mind, hardly a mark of a devout Christian. In his thousands of letters, the name of Jesus Christ never appears. He rarely spoke about his religion, but his Freemasonry experience points to a belief in deism. Washingtons initiation occurred at the Fredericksburg Lodge on 4 November 1752, later becoming a Master mason in 1799, and remained a freemason until he died.
To the United Baptist Churches in Virginia in May, 1789, Washington said that every man ought to be protected in worshipping the Deity according to the dictates of his own conscience.
After Washingtons death, Dr. Abercrombie, a friend of his, replied to a Dr. Wilson, who had interrogated him about Washingtons religion replied, Sir, Washington was a Deist.
Thomas Jefferson
Even most Christians do not consider Jefferson a Christian. In many of his letters, he denounced the superstitions of Christianity. He did not believe in spiritual souls, angels or godly miracles. Although Jefferson did admire the morality of Jesus, Jefferson did not think him divine, nor did he believe in the Trinity or the miracles of Jesus. In a letter to Peter Carr, 10 August 1787, he wrote, Question with boldness even the existence of a god.
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.
John Adams
John Adams
John Adams
Adams, a Unitarian, flatly denied the doctrine of eternal damnation. In a letter to Thomas Jefferson, he wrote:
I almost shudder at the thought of alluding to the most fatal example of the abuses of grief which the history of mankind has preserved the Cross. Consider what calamities that engine of grief has produced!
In his letter to Samuel Miller, 8 July 1820, Adams admitted his unbelief of Protestant Calvinism: I must acknowledge that I cannot class myself under that denomination.
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.
James Madison
Called the father of the Constitution, Madison had no conventional sense of Christianity. 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.
Benjamin Franklin
Although Franklin received religious training, his nature forced him to rebel against the irrational tenets of his parents Christianity. His Autobiography revels his skepticism, My parents had given me betimes religions impressions, and I received from my infancy a pious education in the principles of Calvinism. But scarcely was I arrived at fifteen years of age, when, after having doubted in turn of different tenets, according as I found them combated in the different books that I read, I began to doubt of Revelation itself.
. . . Some books against Deism fell into my hands. . . It happened that they wrought an effect on my quite contrary to what was intended by them; for the arguments of the Deists, which were quoted to be refuted, appeared to me much stronger than the refutations; in short, I soon became a through Deist.
In an essay on Toleration, Franklin wrote:
If we look back into history for the character of the present sects in Christianity, we shall find few that have not in their turns been persecutors, and complainers of persecution. The primitive Christians thought persecution extremely wrong in the Pagans, but practiced it on one another. The first Protestants of the Church of England blamed persecution in the Romish church, but practiced it upon the Puritans. These found it wrong in the Bishops, but fell into the same practice themselves both here [England] and in New England.
Dr. Priestley, an intimate friend of Franklin, wrote of him:
It is much to be lamented that a man of Franklins general good character and great influence should have been an unbeliever in Christianity, and also have done as much as he did to make others unbelievers (Priestleys Autobiography)
Thomas Paine
This freethinker and author of several books, influenced more early Americans than any other writer. Although he held Deist beliefs, he wrote in his famous The Age of Reason:
I do not believe in the creed professed by the Jewish church, by the Roman church, by the Greek church, by the Protestant church, nor by any church that I know of. My own mind is my church.
Of all the systems of religion that ever were invented, there is no more derogatory to the Almighty, more unedifiying to man, more repugnant to reason, and more contradictory to itself than this thing called Christianity.
