From Theological Graffiti:
Fast forward to 2013, when I and three others co-directed the first Open theology conference geared toward non-academics. This conference was supposed to gather all those who have embraced Open theism and are trying to live it out in their everyday contexts. Right away, it became clear we hadn’t fully anticipated just how different were all the other views Open theists hold. There were folks from widely divergent points of view—not just moderate evangelicals, like we expected. Some who attended were dyed-in-the-wool Fundamentalists. They balked at the suggestion that theistic evolution should be accepted by Open theists, and they insisted that the Bible be considered “inerrant.” Open theism had it’s first faction.
The “conservative/progressive” split in any U.S.-based theological movement isn’t so shocking. Virtually every U.S. denomination has some form of it. But what did surprise me was when the non-Fundamentalist Open theists began to splinter into even more factions. The next to demand their views be accepted by all Open theists were those who affirm the early Creeds of the church in addition to the Bible as authoritative.
