Calvin, not Luther was the signal figure at Ratisborn, and if he found the statement acceptable, one must say that this made Charles V’s hopes for reconciliation vitually impossible. Recall that Luther had broken with Erasmus, and now we have a ferocious reasoner in Calvin, whose views were anithetical not only to those of Rome but of Constantinople. The East had not accepted Augustine and the West had softened his view; Now we have the arch-Augustinian, who for the last 25 years of his life dominated the Christian world.
Hmmm, interesting points. That’s Regensburg, not Ratisborn though. It seems to me a figure before Calvin, Aquinus, and his followers were also quite Augustinian. I believe both the Western and Eastern churches though had become prima facia semi-Palagian, by an large though—a stance always popular even since Augustine’s own day.
