This is an interesting question and many, most including me, for a long time, see/saw these words as defining the same thing. I was jarred to the difference by Kris Anne Hall. She spoke on, the US Constitution history and how it became one of America's founding documents. My bride/supervisor had to travel from Independence to The Trinity Baptist in Grove, Oklahoma last week (2-13-14). Kris Anne Hall hour presentation was worth every minute, mile and expense. She is kickass good.
