James Spencer and Ashish Varma return to the diagnoses that narrow the church's vision, this time with fragmentation — the way faithful Christians end up separated from one another not by heresy but by tradition, idiom, and the slow drift of communities that no longer talk across their boundaries.

James opens with a job interview from 2005 where a pastor announced he wanted no one in the role who wouldn't bleed for the Southern Baptist faith. Both men are clear that boundaries have real value; the question is what happens when a community's distinctives quietly become the test of who counts as a Christian at all.

The conversation leans on George Lindbeck's argument that doctrine is second-order — an attempt to make sense of the biblical narrative rather than the thing itself — and on what gets lost when that ordering flips. Along the way: the ecumenical councils and why some councils didn't make the cut, the filioque and the East-West split, Genesis 22 and whether its tension sits in the text or in front of it, and why James has traded getting it right for getting it plausible.
