I don't have the best notes on Brad's presentation, in part because much of his talk is also summarized in his book THE MISSIONAL QUEST.
But here is what I have
"There are no unsacred places, there are only sacred places and desecrated places"--Wendell Berry
He referenced Oldenburg--Great, good place
And he talked about three places where we experience life
First places--Home. Our missional practice there is neighboring. We should offer Biblical hospitality. This is different from entertaining. Hospitality speaks of the LOVE of the stranger. In order to do this we need to have margin in our lives, because "relationships happen in the margins"
Third place--Where we hang out. Our missional task in these places is twofold
1. Identify and engage third places
2. Create third places
3. Support and defend third places
