I don’t have links to such with the Calvinists or even the Mormons. There has likely been some with the Wisconsin Evangelical Lutheran Synod or WELS—a few, as I recall.
But the bulk of such on my part have been face to face with religious leaders of many different denominations and congregations in a variety of contexts across two Continents and half way around the world. I’ve held forth vigorously with a long list of such since about 1967.
In Southern California, I was blessed or cursed to be at least observationally close if not relationally close to quite a number of famous Charismania leadership circles. They certainly caught plenty of such from me.
And, quite frankly, honestly, truly . . . Holy Spirit has led me to lay down ultimatum flavored exhortations to a number such leaders and they were removed from their positions or taken out of this life as a function of their responses. But I haven’t walked in that level of anointing for a long time. That’s not my favorite sort of ‘ministry’ anyway.
By a long shot.
Oh yeah, I would definately say that they would qualify. Their constitution demands a split if there is any disagreement about the one and only way.
