I call “cite” on the Washington prayer. Whether Washington was a believing Christian or not is, and probably will always be, unknown. He certainly was not the sort to proclaim a belief in Christ. The rector of the church that he attended with his wife, James Abercrombie, has said that he was a Deist (as reported by The Reverend Bird Wilson, an Episcopal minister who made an exhuastive study of Washington after his death, and concluded that he was a Deist “and nothing more”).
What IS known is that Washington was scrupulously opposed to praying out loud or in public, especially when he was in office (which was actually a matter of some amusement, as people often tried get to him admit this or that religious belief, and he always coyly avoided their questions). He seemed to consider public prayer unseemly. When speaking of fate/divine type subjects, he also spoke of Providence, rather than God or Christ. The only known mention of Christ in his own writing was a poem he wrote for an assignment when he was thirteen:
Assist me, Muse divine, to sing the morn
On which the Savior of mankind was born
– George Washington, poem, age 13, from Franklin Steiner, The Religious Beliefs of Our Presidents, p. 20
So, while I don’t think the claim that he was a Christian should be dismissed, I am skeptical of purported prayers and such that present the matter as definitive.
This is especially so because there are lots of utterly bunk “founding father” quotes floating around, invented by people like Daniel Barton of Wallbuilders Inc. (and later admitted to). The most famous regarding Washington is a supposed prayer set on a plauqe at St. Paul’s Chapel, Broadway and Vesey Streets, New York City. It contains things like “Almighty God, we make our earnest prayer that Thou wilt keep these United States…” and ends with the standard Episcopal “Grant our supplication, we beseech Thee, through Jesus Christ our Lord. Amen.” However, none of these things appear in the original letter that this is quoted from. This sort of misrepresentation happens all the time. Indeed, the original letter, which mentions only a plain “God” and “Divine Author” is not even in Washington’s handwriting, but his secretaries, who were known to pen and embelish things in his name when he was busy.
Even if you ignore that complication, however, what I think is important to ask is why anyone would want to misrepresent that letter in order to make Washington sound more pious and flowery. The original needs no embelishment, and is certainly highly laudatory of “our blessed religion, and without an humble imitation of whose examples in these things [humility, charity, mercy, etc.], we can never hope to be a happy nation.”
The beliefs of the various founding fathers are complex and diverse. They range from very orthodox Protestant Christian (Hamilton) to regegade Christian (Jefferson) to Deist heretics (Paine, maybe Madison and Franklin). It’s silly to try and pigeonhole an entire country based on their beliefs. In fact, it’s cynically dishonest. For while the religious beliefs of the founders were manifold (and changed over lifetimes as well), they very clearly agreed on one thing: that one’s beliefs were private matters of personal conscience, not to forced on anyone else with the aid of the state, or ever used to deny or specially privelege someone’s participation in public life.
Washington, for instance, was a passionate defender of tolerance, and of basic respect for everyone, regardless of belief.
When securing workmen for his estate, he said: “If they are good workmen, they may be of Asia, Africa, or Europe. They may be Mohometans, Jews or Christians of any Sect, or they may be Atheists.” Washington, letter to Tench Tilghman, cited in Paul F. Boller, George Washington & Religion. page 118
When clergymen complained that the Constitution did not reference Christ, Washington replied: “I am persuaded, you will permit me to observe, that the path of true piety is so plain as to require but little political direction. To this consideration we ought to ascribe the absence of any regulation, respecting religion, from the Magna-Carta of our country.” Washington, Papers, Presidential Series, 4-274
He was quite a character (and nothing like the saint he is often portrayed as: for instance, it’s rarely mentioned that he had something of an amusing vain streak for the latest fashions
).
