It’s a debate that isn’t going to go away any time soon. The nature of valid ongoing revelation is under debate.
I would believe any valid answer is going to be Jesus centered rather than denomination-centered or congregation-centered. Who gets glorified, God or man?
The date for a unified church and the unconfused literal authority associated directly with such a thing, until something happens to reverse it, has passed. Luther and other reformers, from that standpoint, are only late to a sad party that already began with the Roman and Orthodox churches. We are thrown on Christ and the bible by necessity, to weather this dark season of the universal church until Christ shall personally call it back together.
The ultimate test of a part of the church as a vehicle through which Christ leads, would be the visible results. Does this look unmistakably like Christ. Does this look like the work of a God “with which all things are possible”? The presence of complete mortal perfection isn’t needed to see the unique approaches to the holy that the Lord works in this mortal world.
I think there is room for all to get off their own private high horses here.
What particular "churches" are still receiving "ongoing revelation" or even debating about it?
