He said 'dunghill', but not quite in the manner in which you portray. Jefferson believed the Bible had been 'contaminated' by the early Christians in an effort to make Christianity more appealing to pagans. His desire was to glean the *pure* teachings of Jesus from the chaff of early Christian meddling.
In his letter to John Adams dated 1813, he wrote:
I have performed this operation for my own use, by cutting verse by verse out of the printed book, and arranging the matter which is evidently his, and which is as easily distinguishable as diamonds in a dunghill."
Here is the actual letter if your interested in the truth instead of parroting what you've heard:
(The 'dunghill' reference can be found toward the bottom of the 2nd paragraph)
To John Adams Monticello, Oct. 12, 1813
while the phrases "laws of Nature" and "Nature's God" have a lot more to do with Deism than Christianity.
Our legal system says otherwise- From the LEGAL definition of 'natural law'
n. 1) standards of conduct derived from traditional moral principles (first mentioned by Roman jurists in the first century A.D.) and/or God's law and will. The biblical ten commandments, such as "thou shall not kill," are often included in those principles.
For giggles & grins, another Jeffersonian quote:
of them, who have perverted them for the structure of a system of fancy absolutely incomprehensible, and without any foundation in his genuine words. And the day will come when the mystical generation of Jesus, by the supreme being as his father in the womb of a virgin will be classed with the fable of the generation of Minerva in the brain of Jupiter. But we may hope that the dawn of reason and freedom of thought in these United States will do away with all this artificial scaffolding, and restore to us the primitive and genuine doctrines of this the most venerated reformer of human errors."
Thomas Jefferson, in a letter to John Adams, April 11, 1823
Nice try though.
Back at 'cha!
