I'm not aware of anything more specific than this letter regarding Jefferson's view of the relationship between church and state. A "one-way wall" probably is not the best way to describe what I think Jefferson believed, but my point is that today people are erroneously using Jefferson's phrase "wall of separation between church and state" to mean something Jefferson never meant.
To put it simply, I think the Establishment Clause has been interpreted far too broadly in recent years.
