You need to get a refund for the course.
That was too many years ago.
It seems one more doctrine for Christians to fight over. It's a valid word and if it's all I learned in that course, I got my first understanding of how Christians bickered to the point of bloodshed over Jesus' teachings.
I just don't feel like arguing about it. I tried to post benign material which I believed to be of merit, without rancor either way on my part, and people either ignore it or you pick on me for what I'm not sure.
I shouldn't have said where I first learned that word and the context was the Reformation, not theology.
