Scripture is Acts 4: 23-33 and the focus is on how the early church was in unity.  I proffer that they were in unity in terms of mission, vision, and values.  The Resurrection is the engine that drove the growth in of the early Church.  

The focus here is on people, not buildings, or denominations.  This is an initial exploration of changing our belong, believe, become to something new and different.  Hospitality, helping, hope and healing.  There is a both an inward and outward focus simultaneously:  Caring for their people and carrying the story into the world.
