I think you misunderstood me maybe
.. I was agreeing with you about proof...
I do not regard Calvin a trigger word.. I like a lot of what he states but definitely it was his contention that works had to follow faith pretty much how Judges sees it....
Calvin's ideas have permeated doctrine throughout history both the good and that not so good.
My point is the idea that "proof must exist" goes back to the Reformation and I myself do not see it supported by scripture.
Hope I have clarified.
