Abstract:
This article is an exercise in Practical Ecclesiology. The author reflects on church, mission and
ethics from historical, hermeneutical and strategic perspectives. Using the ecclesiology of Karl
Barth as a point of departure, the author argues that the church needs to be church if it wants
to be a credible witness to the Gospel of Jesus Christ. Integrity is essential if a church wants to
be missional. Integrity means the church has to become what it already is, the body of Christ.
This contribution is dedicated to Prof Graham Duncan, professor emeritus of church history
(University of Pretoria), a man of integrity and dedicated to the missional calling of the church.
