I'll leave a few quotes so that you can see other opinions by some of those signers of the documents you cite:
I think you'll find these FAR more inciteful and in opposition to what you are saying:

John Adams in a letter to Thomas Jefferson:

"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!"

James Madison:

"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:

"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."
