At first, Washington refuse participate communion and later he had. So there are different views and as of different studied of Washington's letters he wrote, it was like a journal.
No, it was a letter written by his Christian minister, Rev. Dr. Abercrombie, to a Christian evangelist. Rev. Abercrombie told him that he died a Deist, not a Christian. George Washington was unlikely to be a Christian.
Abe Lincoln was the same as well.
Here's an actual excerpt from Herdon to Mr Remsburg regarding Abe's beliefs:
"Before I wrote my Abbott letter, I diligently searched through Lincoln's letters, speeches, state papers, etc., to find the word immortality, and I could not find it anywhere except in his letter to his father. The word immortality appears but once in his writings.
If he had been asked the plain question, "Do you know that a God exists?" he would have said: "I do not know that a God exists."
At one moment of his life I know that he was an Atheist. I was preparing a speech on Kansas, and in it, like nearly all reformers, I invoked God. He made me wipe out that word and substitute the word Maker, affirming that said Maker was a principle of the universe. When he went to Washington he did the same to a friend there.
Mr. Lincoln told me, over and over, that man has no freedom of the will, or, as he termed it, "No man has a freedom of mind." He was in one sense a fatalist, and so he died. He believed that he was under the thumb of Providence (which to him was but another name for fate). The longer he lived, the more firmly he believed it, and hence his oft invocation of God. But these invocations are no evidence to a rational mind that he adopted the blasphemy that God seduced his own daughter, begat a son on purpose to have mankind kill him, in order that he, God, might become reconciled to his own mistakes, according to the Christian view.
The best evidence this side of Lincoln's own written statement that he was an Infidel, if not an Atheist, as claimed by some, is the fact that he never mentions the name of Jesus. If he was a Christian, it could be proved by his letters and speeches. That man is a poor defender of a principle, of a person, or a thing, who never mentions that principle, person or thing. I have never seen the name of Jesus mentioned by Mr. Lincoln.
Mr. Lincoln never mentioned the name of Christ in his letters and speeches as a Christian. I have searched for such evidence, but could not find it. I have had others search, but they could not find it. This dead silence on the part of Mr. Lincoln is overwhelming proof that he was an unbeliever.
While Lincoln frequently, in a conventional way, appeals to God, he never appeals to Christ nor mentions him. I know that he at first maintained that Jesus was a bastard, and later that he was the son of Joseph and not of God.
Lincoln was not a Christian in any sense other than that he lived a good life and was a noble man. If a good life constitutes one a Christian, then Mill and a million other men who repudiated and denied Christianity were Christians, for they lived good and noble lives."
