The Church universal also has a set of overlapping responsibilities, but how these responsibilities are translated into the work of individual churches is a tension of its own. Local churches are first obligated to their own members, to preach, worship, disciple, and administer the sacraments. Adding anything beyond this to any individual church is tying on a burden too great to bear. Yet the Body of Christ spread across the world is also responsible for sending messengers of the Gospel to places that have not yet heard it, meeting the needs of the poor (local and distant), and advocating for justice in whatever society they find themselves in. (I would draw primarily from Isaiah 58 as the source of the lattermost impetus.) The Body of Christ also has an obligation to be in communication with itself such that the hand can know if the eye is suffering and then do something about it.
This task might seem impossible, but the power of the Holy Spirit among God’s people allows us to order ourselves according to the moral obligations we have to one another and to the world. We seek in prayer to know which people in need we ought to be in proximity to, and we obey accordingly as we embark on whichever road to Jericho we are called to. Some may physically remain wherever they are; others may move across town, across the country, or across the world. The wealth of believers, once yielded to the direction of the Holy Spirit, also has centripetal and centrifugal forces acting upon it but should in general go to where there is the greatest need and the least knowledge of the Gospel.
A long, complex essay, incisive and provocative. Every thoughtful Christian should read it. I hope to comment more fully later.
