The Holy Trinity: In Scripture, History, Theology, and Worship

Robert Letham (MAR, ThM, Westminster Theological Seminary; PhD, Aberdeen University) is professor of systematic and historical theology at Union School of Theology in Bridgend, Wales, and the author of a number of books, including The Holy Trinity, The Lord's Supper, and Union with Christ.

The doctrine of the Trinity demands the careful study of biblical exegesis, historical theology, Christian orthodoxy and heresy, interdenominational differences and discussions, systematic theology, and practical implications. Robert Letham’s outstanding book (this substantially updated and expanded version is even better than the first) covers all the bases well, and yet still leaves us in awe of the incomprehensible mystery of our triune God. -- Joel R. Beeke, President, Puritan Reformed Theological Seminary

The doctrine of the Trinity is the foundation stone of a distinctively Christian theology, and interest in it continues to grow. In this revised version of his earlier study, Bob Letham takes us through its many aspects, including the controversies that have surrounded it, and guides us to an understanding based on Scripture, faithful to the orthodox tradition and sensitive to today’s needs. Essential reading for us all. -- Gerald Bray, Research Professor of Theology, Beeson Divinity School, Samford University

It is a pleasure to recommend the second edition of Bob Letham’s The Holy Trinity. This ancient doctrine has stirred up new discussion since his acclaimed first edition, but the author has kept up with what has been going on. So I suppose it is fair to say that this augmented text does not contain the author’s last word on this fundamental Christian mystery, but he has given his readers his latest word. In it, Letham continues to display more of his learning and more of his characteristic watchfulness when met by the latest Trinitarian neologisms and analogies. -- Paul Helm, Emeritus Professor of the History and Philosophy of Religion, Kings College, London

This is a very solid, well-reasoned, and well-researched volume on the doctrine of the Trinity. Letham is a master of historical theology. He brings his immense learning to bear on many contemporary Trinitarian issues in an astute and compelling way. Anyone who reads this work will be greatly informed and enriched. -- George Hunsinger, Hazel Thompson McCord Professor of Systematic Theology, Princeton Theological Seminary
