I'd like to see the rest of that as I've ever saw that one before. I have see this however...
"I am a Christian, that is to say a disciple of the doctrines of Jesus. I have little doubt that our whole country will soon be rallied to the unity of our Creator and, I hope, to the pure doctrine of Jesus also."
What Jefferson meant by that was, much like Gandhi, he admired the
doctrines of Jesus, meaning his peaceful ideals.
Given the whole of Jefferson's writings and thoughts on the matter, no one could come to the conclusion that he was a Christian who believed in the divinity of Jesus or the Christian religion, nor that he thought well of it.
Another Founding Father said this....
"It is impossible to govern the world without God and the Bible. Of all the dispositions and habits that lead to political prosperity, our religion and morality are the indispensable supporters. Let us with caution indulge the supposition that morality can be maintained without religion. Reason and experience both forbid us to expect that our national morality can prevail in exclusion of religious principle."-George Washington
I find it odd that we revere our founding fathers with such awe as to their personal characters and opinions. They had human failings like anyone else, and erred in their opinions as much as anyone else. Washington, Jefferson and Madison, very liberal in their ideals of freedom, all had slaves, for example. They all changes their opinions on matters political and religious matters and with respect to freedoms over the course of their lives and presidencies during very tumultious times. Quite mining does very little to shed the light of their thoughts on our times of today.
Suffice to say if you sat down to dinner with the three above, I think it very unlikely that you would come to the conclusion that they are Christians (though admittedly, Washington was probably the closest of the three).
And, as this report states, it appears that Washington was wrong.
