"La Due presents a historical survey and authoritative and readable summaries of prominent Catholic, Protestant, and Orthodox theologians. He begins with the Old Testament scholarship of theologians such as Gerhard von Rad and Walter Brueggemann. He then chronicles the doctrine's formulation through the seventh century in church councils and in the writings of the earliest church theologians.

He examines the doctrine as it develops from the Middle Ages to the end of the nineteenth century in the works of theologians ranging from Aquinas to Schleiermacher." "Moving on to the twentieth century, La Due explores the contributions of Catholic thinkers such as Rahner and La Cugna and Protestant theologians such as Barth and Moltmann. Finally, he outlines Orthodox, Liberation, Feminist, and Process contributions to the discussion of the Trinity."--BOOK JACKET.
