Ephesians 1:14 and 1:22, 23 as a scriptural maximum-minimum for ecclesiology. Against the background of a membership decline in mainstream churches in South Africa and abroad, and conscious of the theological debate in which a missional ecclesiology is presented as at least part of the modern-day solution to the problem, this article points in the direction of a Christological ecclesiology as an important ecclesiological point of departure. The article gives an exegetical outline of Ephesians 1:14 and 1:22, 23 as a (...) critical maximum-minimum for a Christological ecclesiology and as a means of making missional ecclesiology more acceptable.
