You know I love ya, but … 😉 I feel like I have to confess … that I am a post-congregational Christian. And I think your overview makes a mistake in mixing post-church (or, I prefer the term post-congregational) Christians with those who are de-churched non-Christians (those who have grown up in Christianity but have rejected it later in life for whatever reason).
Although your overview here (which I just found ironically by doing a Google search on “post-congregational”) makes it sound as if all post-congregational Christians are “lost souls,” I am finding that the opposite is in fact true. Those I know who are choosing the route of post-congregationalism (if that’s even a word) are doing so out of a missional motivation to intentionally be the Church outside of traditional church structures in order to be salt and light amongst a largely de-churched world.”
Steve Knight, a Post-Congregational himself, has begun a dialog with me in comments to a post I made on that topic on Leadership Network’s Digital Blog. See his entire comment and my response here.
