Ted Peters brings Trinitarian theology conversation to a new level by examining the works of Karl Barth, Karl Rahner, Eberhard Jungel, Jurgen Moltmann, Robert Jenson, Wolfhart Pannenberg, and Catherine Mowry LaCugna. He highlights talk about the becoming of God by process theologians, sexism in Trinitarian language by feminists, and divine and human community by liberation theologians. Peters addresses the relationship of God's eternity to the world's temporality, and claims that thinking of God as Trinity affirms that the word "God" applies to both eternity and temporality.
This is a short book that introduces the reader to trinitarian theology. The first three chapters introduces standard problems of trinitarian theology and the basic history, whether early church (notions of substance, person, the filioque clause, Augustine and the Cappadocians, etc.) or the trinitarian revival of the last century (Barth, Rahner, Pannenberg, Moltmann, Lcugna, Jenson, etc.).
The final chapters is the real substance of the book where the author works through understanding God's time and eternity in light of recent physics of the nature of time. It is an excellent discussion with a good constructive statement at the end of the chapter.
