To not digress too much, though I felt Tom deserves a bit of a counter view. Though Thomas Jefferson was a very real and very flawed man in many ways he also contributed greatly to our political philosophy and system as can be imagined in the Declaration of Independence. There are many genius bit of ideas and knowledge expressed by him including his active efforts to separate Church and State (and being the origin of that phrase). There are many more contributions of the same nature from him. This does not wash out the multiple bad things he did.
Just a side note. His letter was about not having a national religion not taking God out of Government. They held church in the captital.
Now back on track
