Using Paul's letter to the Romans as the foundation for constructing a fuller exposition of Paul's whole theology, Dunn's thematic treatment clearly describes Paul's teaching on such topics as God, humankind, sin, Christology, salvation, the church, and the nature of the Christian life. In the process Dunn engages, in a concise way, with what other important scholars have said regarding each area of inquiry.

His work represents a major contribution to the ongoing discussion regarding what Paul's theology is and what its continuing relevance is to the study and practice of religion and theology.
