Hmmmmm....one has to wonder if there were any great Arminian preachers who switched to the Reform view and never renounced their Arminian church?
Arminians who switched to the Dortist view is a better way of putting it, however, I get your point.
I'm trying to think of one, because there probably is....just on the basis of probability if nothing else.
I don't know Whitefield's early history, so I don't know what route he traveled in getting to his dortism....but he's a possibility.
It's a possibility with just about any of the Anglicans since they had both ends of the calvinist spectrum operating within their church.
Mostly restraining myself from responding in kind.
