Malcolm B. Yarnell III is Research Professor of Systematic Theology at Southwestern Baptist Theological Seminary in Fort Worth, Texas, where he enjoys exploring theology with his graduate students. He is the author of three widely-reviewed books, the first on systematic theology, The Formation of Christian Doctrine (B&H Academic, 2007); the second on biblical theology, God the Trinity: Biblical Portraits (B&H Academic, 2016); and the third on historical theology, Royal Priesthood in the English Reformation (Oxford University Press, 2014). He recently published a treatise on philosophical theology, John Locke's 'Letters of Gold' (Oxford, 2017), and co-authored a book on covenant ecclesiology, The Fourth Strand of the Reformation (Oxford, 2018). Dr. Yarnell has edited twenty books and journal issues and has contributed more than 125 essays, academic and popular, in the fields of systematic and historical theology as well as biblical theology and public theology. His next three scheduled volumes include a biblical theology of the Holy Spirit and a major text on the doctrine of special revelation with David S. Dockery. When not teaching, writing, or speaking to international academic or church audiences, Malcolm's personal passion is to engage in the contextual theological interpretation of the canon of Scripture through weekly teaching in the local churches.
