“It is a privilege to serve as the doorman to welcome readers into the remarkable world of reflections that Dr. Vern Poythress provides for us in this substantial work. . . . [He] undertakes the task of helping us to see the sheer wonder of God as we reflect on his self-testimony. . . . We want to be able to say with Jeremiah, ‘Let him who boasts boast in this, that he understands and knows me, that I am the Lord’ (Jer. 9:24). In Knowing and the Trinity, Vern Poythress helps us to do precisely this. . . . I bid you to explore and enjoy!”

—Sinclair B. Ferguson, Chancellor’s Professor of Systematic Theology, Reformed Theological Seminary

“In this fascinating and highly accessible book, Dr. Poythress puts his perspectival method to work in a wide-ranging exploration of Trinitarian theology. Underlying his discussion is the conviction that while this is a mystery surpassing our capacities, God has revealed himself in creation and grace, his triune fingerprints evident wherever we turn. Any discussion of the doctrine of God should take Poythress’s important contribution into serious consideration. I know of nothing else quite like it.”

—Robert Letham, Professor of Systematic and Historical Theology, Union School of Theology (formerly Wales Evangelical School of Theology)

“In recent decades, many evangelical scholars, students, and laypeople have found triperspectivalism extraordinarily helpful, but they have also found it confusing. Vern Poythress has given us what amounts to a primer on this subject. His explanations are brief and clear. He securely anchors his outlooks in the Scriptures and in orthodox Trinitarian theology. The illustrations and glossary make Poythress’s discussions accessible to a wide range of readers. Study questions encourage both theoretical and practical reflection. This book is a window into ways of thinking about and living the Christian faith that will greatly benefit us all.”
