Richard Muller, a world-class scholar of the Reformation era, examines the relationship of Calvin's theology to the Reformed tradition, indicating Calvin's place in the tradition as one of several significant second-generation formulators. Muller argues that the Reformed tradition is a diverse and variegated movement not suitably described either as founded solely on the thought of John Calvin or as a reaction to or deviation from Calvin, thereby setting aside the old "Calvin and the Calvinists" approach in favor of a more integral and representative perspective. Muller offers historical corrective and nuance on topics of current interest in Reformed theology, such as limited atonement/universalism, union with Christ, and the order of salvation.
