he pointed out that the flaw in Calvinism is its reliance on humanly limited reason in building the doctrine of double predestination.
I would think the opposite would be the case. I think the unreasonableness of the doctrine explains its unpopularity. Unaided reason tells us that God is Good. Therefore, it would be impossible for Him to will damnation for some people from all eternity, particularly without regard to their actions and decisions for or against God.
Yes, but the Calvinist unaided reason tells us that God is omnipotent and omniscient, therefore if X is eternally damned, then God made him. Charles Henrickson's point (really, the Lutheran Synod's position as I understood it) was that these two views that humans have of God,-- God of love and God of power, are not reconcilable under pure reason.
This may not be a proper thread to discuss this at length.
Pastor, why do you think the Muslims persist in their faith?
