Church is about people, practical activity and Christian living. The doctrine of the Trinity seems not only about theology, but about that side of theology which has very little to do with everyday realities like the church. Such thinking, to borrow from Edmund Blackadder, could hardly be wronger. It is by understanding herself in the light of the Trinity that the church fulfills her calling. The church is a visual aid of the Trinity. Something of God's three-in-oneness is reflected in the life of his people.
