If I’m understanding Halden and Ry correctly, the institutional and confessional division of Christianity is a very serious issue that constitutes an offense against the Gospel. In addition, attempting to come up with a solution to that problem is an offense against the Gospel, because all existing attempts to find a solution start from the premise that the church really is divided.
The answer is to recognize that “in Christ,” our apparent divisions are unreal and that there is no obstacle to immediate unity — and then…. Well, I don’t know what we should do next, because all I can think of is talking to other like-minded people about how we can get past the divisions, but that’s “negotiation” and therefore sinful.
Perhaps the really important thing is to have the correct theological opinions and then not do anything concrete, because part of having the correct theological opinions is believing that human agency is somehow inherently problematic or prideful.
In short, I unsubscribed from Halden’s blog a while back and this post reminds me why.
