The Trinity: Evidence and Issues is a modern up to date defense of the trinity. Morey has an excellent introduction where he establishes epistemological issues. He approaches the study of the Trinity using an analytic, deductive, or a priori method. This entails going from the whole to the parts. He defends the a priori method because the Trinity does not originate with human experience but with special revelation. Morey outlines the differences between humanist, liberal, and orthodox approaches to Scripture. The author does not believe that one can approach Scripture without presuppositions, since even the presupposition that one has no presuppositions is a presupposition. He defends the doctrine of God’s Oneness and His incomprehensibility. The incomprehensibility of God is an important doctrine for the Trinity, since the Trinity is incomprehensible. If God is truly infinite we would expect that there would be things about Him that we could not fully understand. Morey has a very effective approach in that he continually asks if the Unitarian/Arian/Jewish view is correct, what would we expect to find? If the Bible teaches the Trinity we would expect to find plural nouns, pronouns, verbs, and adjectives used of God. On the other hand if the Arian view were correct we would not expect to find these things. His approach to the biblical evidence was very helpful as it clarifies what sort of evidence would be consistent with a particular viewpoint before one studies the issue.
He then covers the OT evidence for the multi-personal God. He discusses verses where plural nourns, verbs, pronouns, and adjectives are used of God as well as all the references to Theophanies in great detail. He also has a very helpful discussion of the evidence for the Trinity in the Old Testament.
He has a chapter on the Dead Sea Scrolls and how that before Christ came Jewish commentary on Messianic verses were consistent with what Christians contend in relation to Christ today. The purpose of this chapter was to show that the NT view of Messiah was thoroughly Jewish and not pagan. He proves this conclusively with quotes from the Dead Sea Scrolls as well as Targums and Pseudopigraphic literature.
