It is my pleasure to introduce Timothy Miller’s book.
Miller’s book has arisen from spending much time and energy in examining triperspectivalism, as developed especially by John Frame and me. Miller is a sympathetic analyst who has succeeded in understanding triperspectivalism from the inside, rather than from a distance, and so you will find in his book an accurate portrayal. The presentation is also clear and helpful for readers. At the same time, Miller has applied his own insights to explain triperspectivalism in his own way. He has rightly been willing to point out areas of weakness and areas that could use further development. He has offered some development himself, by proposing some terminological labels for clarification and by exploring whether there is an intrinsic “order” in some of the triples, an order mirroring the intrinsic order in the Trinity.
All this work makes his book a valuable resource on the subject. I am grateful that someone with Miller’s ability has seen fit to offer the first published book-length study of triperspectivalism, and a good book at that. It has helped me to gain perspective (!) by hearing someone else’s voice, and seeing details noticed that I had not attended to myself.
John Frame and I have hoped that the methods of triperspectivalism might be of service for the glory of God and for the edification of the people of God. May Miller’s book also contribute to these goals, by helping the people of God to serve him with all love and faithfulness.
