I wanted to recommend an article by Rev. Michael Ives. The article is called "Parish Evangelism: Rediscovering Focus in Evangelistic and Pastoral Effort." It is a very interesting call to return to a more parish-focused model of church ministry. I think his thoughts warrant careful consideration. There is definitely something to be said for re-implementing, to some degree, a more region-based, local concept of ecclesiastical jurisdiction, both in terms of the church's ministry to members as well as to non-members and non-Christians. He's also written about this here (starting on p. 9).
Rev. Ives is minister of the Presbyterian Reformed Church in East Greenwich, Rhode Island.
