Over on the aomin blog I recently posted Tradition and the House Church Movement. Someone stopped by here and left me an interesting pdf link: Is House Church an Apostolic Tradition? by Michael W. Adams.
My comments on the aomin blog are entirely based on the ISI interview with Mr. Atkerson. I imagine Mr. Atkerson has a more nuanced presentation of "tradition" somewhere in written form. The pdf is a book review of a pro-house church book. I'm sure I only scratched the surface with my review of the interview.
