Newt Gingrich on this link spreads one of David Barton's phony quotations. His page says:
Washington’s personal journal provides more evidence of his deep faith:
"It is impossible to rightly govern the world without God and the Bible. It is impossible to account for the creation of the universe, without the agency of a Supreme Being. It is impossible to govern the universe without the aid of a Supreme Being."
Sorry, Washington never said this and these utterances and not found anywhere in the primary source record. They are part of David Barton's phony quotations, which he admonished his followers to no longer pass. Maybe if he didn't try to euphemize them with the label "unconfirmed," fewer folks would still be passing them.
