The doctrine of the Trinity is foundational to Christian theology, though sometimes daunting—error is probable when biblical texts are read selectively. A careful study of the whole counsel of God, however, will bring needed clarity. In a work geared especially toward leaders in the church, scholars of the Trinity—including Richard Bauckham, Robert Letham, Michael Reeves, and Scott Swain—overview Old Testament teaching, provide Trinitarian readings of the entire New Testament corpus, and explore the practical relevance of the doctrine to prayer, worship, and other aspects of Christian life and ministry.
