Ah, Calvin "corrected" Augustine. He also "corrected" Luther, eh? And "corrected" Paul, I suppose? What an ego!
Do you understand, DB, that is is strong evidence of the charge that the real result of the Reformation is that one assumes the role of Pope in the creation of their own theology.
Calvin corrected Luther and Augustine. The Restoration was full of folks who corrected the Reformers. Each generation brings yet another correction to "Christianity". What makes them more correct? The fact that they lived after the preceding bunch?
The evidence is that these increasing and increasingly myriad number of religions evolve as their beliefs evolve away from the Faith. How many Protestants in the US actually hold Christian beliefs anymore?
What Christian beliefs? The Trinity, for one. Anti-abortion, for another. The Real Presence. The Sacraments. The Apostolic succession. The laying on of hands during ordaining to the clerical status. And so on - these are the ancient Christian beliefs.
