Dialogic preaching

Brian Colmery has begun looking at dialogic preaching at Sycamore:

Preliminary evaluation: dialogic preaching can be a good thing. What we need is a theologically sound definition, and we are working towards one now. We have two boundaries (one, really): God’s word must be allowed to stand as authoritative over and above the thoughts, emotions, or logical arguments of those in the congregation. And over the preacher.
