I've been enjoying a discussion on Penal Union versus Penal Substitution
over at Jeremy's (the Parable Man) site. They're playing on theological high
ground but simple questions aren't scorned and even adds to the very thrust of
the arguments on both sides. Perhaps you'd like to pitch in, but mind you, it's
not acidic in the least. These folks (Rebecca, Wink and Jeremy) are having an
honest, thought provoking discussion without stepping on each other's toes or
calling any names. Very enjoyable and you can read for yourself in these links.
