This one-volume introduction to systematic theology draws deeply on the catholic and Reformed heritage to present the major doctrines of the Christian faith, displaying the power of theological retrieval for the church's renewal. Leading Reformed theologians, such as Kevin Vanhoozer, John Webster, Michael Horton, and Oliver Crisp, offer the "state of the question" on standard theological topics and engage in both exegetical and historical retrieval for the sake of theological analysis. The book represents the exciting new theological trajectory of Reformed catholicity.
