In recent years, debates over Trinitarian doctrine have emerged within evangelicalism. In Trinitarian Theology, contributors Bruce Ware, Malcon B. Yarnell III, Matthew Y. Emerson, and Luke Stamps discuss theological methods for forming the doctrine of the Trinity, and the the implications in applying that doctrine to complementarianism. Is this discussion important? The subject matter of Trinitarian Theology casts a long shadow over our faith. The Trinity is central to Christianity, for the vibrancy of our churches, and for the clarity of our witness in the world. The heart of Christianity is trinitarian, because central to the salvation story is the relationship between the Father and the Son. In short, this discussion is of great importance.
