I'm a Christian and I believe that also.
George Washington, the first president of the United States, never declared himself a Christian according to contemporary reports or in any of his voluminous correspondence. Washington Championed the cause of freedom from religious intolerance and compulsion. When John Murray (a universalist who denied the existence of hell) was invited to become an army chaplain, the other chaplains petitioned Washington for his dismissal. Instead, Washington gave him the appointment. On his deathbed, Washinton uttered no words of a religious nature and did not call for a clergyman to be in attendance.

In the political documents, correspondence, and other writings of Washington, few references to the prevailing religion of his day are found. In no instance has he expressed a disbelief in the Christian religion, neither can there be found in all his writings a single sentence that can with propriety be construed into an acknowledgment of its claims. Once or twice he refers to it in complimentary terms, but in these compliments there is nothing inconsistent with the conduct of a conscientious Deist. Religions, like their adherents, possess both good and bad qualities, and Christianity is no exception. While there is much in it deserving the strongest condemnation, there is also much that commands the respect and even challenges the admiration of Infidels. Occupying the position that Washington did, enjoying as he did the confidence and support of Christians, it was not unnatural that he should indulge in a few friendly allusions to their religious faith.
In his "Farewell Address," the last and best political paper he gave to the Christian religion is not once named. In this work he manifests the fondest solicitude for the future of his country. His sentences are crowded with words of warning and fatherly advice. But he does not seem to be impressed with the idea that the safety of the government or the happiness of the people depends upon Christianity. He recommends a cultivation of the religious sentiment, but evinces no partiality for the popular faith.
It would appear that we'll never know if Washington was a Christian or not. But, do you not find it somewhat strange that, if he was a Christian, he never declared so (even on his deathbed)? From my experience, people of faith tend not to be so secretive about their beliefs...<
