In the last thirty years, books on the Trinity have abounded. There seems to be a fascination with this mysterious topic, especially among systematic theologians. This present book has no intention of adding to the plethora of treatises on the Trinity. The main question with which it is concerned is what is really scripturally tenable with regard to the Trinity and what is unwarranted theological construction or even speculation. What takes shape here is a story: how the doctrine of the Trinity developed over the subsequent centuries from the traces in Scripture to a centralized dogma at the heart of Christian teaching. We witness in this an evolution from proclamation to controversy to speculation. What are we to make of this doctrine? How do we articulate the biblical faith today?
