Along with James Madison, another Virginian who was fairly silent on his religious beliefs was General George Washington. No doubt Christianity, and John Calvin's Exposition of it, was the greatest influence on the American Experiment. Calvin's theory of "Solidarity" is the basis and foundation of Republican Representative Government. Solidarity refers to how an individual refers to a group, nation, or mankind, etc. The group is then viewed and treated in relation to its head or King. Solidarity is the basis of the human race having worth and dignity, as man is made in the image of God, His image imputed by Adam to us (Gen. 1:26-27; James 3:9). Solidarity is the basis for: election, the Levitical Priesthood, Corporate Guilt and Punishment, and Even For the Righteous. Egypt's punishment based on the sins of a few is a classic example.
The Bible teaches the acts and decisions of one's representative are viewed and treated as being one's own acts and decisions. If our representatives declare war, you and I have declared war. Representatives for the mass of people was started by God as far back as Exodus 18. Because man is depraved (Calvin's first point in his five points of Calvinism), checks had to be established to limit his power. The Separation of Powers Doctrine, etc. was derived from the work of John Calvin.
George Washington and the Founding Fathers in general, believed in Calvin's Human Depravity, and they designed our government to reflect that depravity. Far from making a distinct declaration of Washington's faith, below is strong evidence of Orthodoxy, as these notes are in his own handwriting, and apparently has his signature. Since Washington approved these words by his signature, he may have added these words himself. Washington's notes for his Inaugural Address show Calvin's influence:
"The blessed Religion revealed in the word of God will remain an eternal and awful monument to prove that the best Institutions may be abused by human depravity; and that they may even, in some instances be made subservient to the vilest of purposes. Should, hereafter, those who are intrusted with the management of this government, incited by the lust of power & prompted by the supineness or venality of their Constituents, overleap the known barriers of this Constitution and violate the unalienable rights of humanity: it will only serve to shew, that no compact among men (however provident in its construction & sacred in its ratification) can be pronounced everlasting and inviolable--and if I may so express myself, that no wall of words--that no mound of parchmt can be so formed as to stand against the sweeping torrent of boundless ambition on the one side, aided by the sapping current of corrupted morals on the other." [bold face mine]
-George Washington, First Inaugural Address Fragments 1789. The Papers of George Washington Documents.
Washington made other comments about his faith that can be construed, however, below, is most likely a spurious letter; most of Washington's fake letters have no date:
"We have abundant reason to rejoice that in this land the light of truth and reason has triumphed over the power of bigotry and superstition and that every person may here worship God according to the dictates of his own heart."
-George Washington, To the members of the New Church at Baltimore.
So why do secularists claim Washington was Arian? Isn't that appellation a superstition? They make that claim because GW claimed in The 1783 Circular to the States refers to Jesus as "the Divine Author of our blessed Religion." GW's use of "superstition" then, must refer to something other that Scripture, most likely added revelation, and heresy.
If Washington claimed Jesus was Divine, who can claim he denied the Trinity, as well as his understanding man was depraved and need of redemption, which man could not provide, thereby man needing a Divine Redeemer?
As to GW's faith, there is evidence on both sides, however Calvin's Human Depravity need not be disputed.
