Theology, to be Christian, is by definition practical. Either it serves the formation of the church or it is trivial and inconsequential. Preachers are the acid test of theology that would be Christian. Alas, too much theology today seems to have as its goal the convincing of preachers that they are too dumb to understand real theology. Before preachers buy into that assumption, we would like preachers to ask themselves if the problem lies with theologies which have become inconsequential.
