As we start considering what planning we need to do for our future, one thing we will need to face fully an a real, instrospective questions. One of them is, "Are we, as a congregation (including the pastor!) really ready to reach out to unchurched people and receive them into our wider church life?"
A definition is called for. People who write about evangelism generally refer to "unchurched" people as those who are not part of a Christian fellowship and never really were except perhaps very temporarily. As for people who were longer-term participants in a church but who do not presently attend, I have usually seen them referred to as dischurched. These are awkward constructions, of course, and places labels on people that they may not agree with or like. Nonetheless, I think the distinction is important.
