In Understanding the Divine, Richard A. Muller clarifies concepts and distinctions used by Reformed theologians of the sixteenth and seventeenth centuries to discuss the essence, attributes, and Trinitarian nature of God. He wipes away caricatures of Calvin and succeeding generations of Reformed theologians as revolutionary thinkers by showing where they retrieved their concepts, the contexts that demanded them to employ those ideas, and what they actually meant. Reading these essays, one comes to see the Reformed tradition as a conservative movement that developed patristic and medieval understandings of God in ways to address emerging problems and concerns of their day.
