It sounds like it’s the name for an effort to find, and focus on, the positive aspects of the Church through all of history (including recent history) rather than the (simpler) method of focusing on what we think has been wrong.
I’ll be the first to admit that I have focused on what’s wrong far too many times, so this is a breath of fresh air for me. It’s much easier to see what’s going wrong than it is for us to overlook what’s wrong and see past it to what is right
But the big question then becomes: what does it actually LOOK LIKE for people to start living this “deep church”? Seems like the answer to that is going to be something that’s up to all of us to create… What will we do to make this a reality? What will it take?
