Most churches accept the doctrine of the Trinity, and their theology is at least somewhat Trinitarian, but very few emphasize the Trinity as the source of the gospel. The doctrine of the Trinity is not a side point, or just one of many other doctrines. It should be the organizing principle for other doctrines. Whether we are talking about sin or salvation or the church, we want to ask, how does the doctrine of the Trinity help us understand this particular doctrine?
