How does John Calvin understand and depict the relationship of God with humanity? Until this study, the most influential readings of Calvin have tended to assume a dialectical divine-human opposition as fundamental to his thought. In this fresh consideration of Calvin's Christian vision his consistent and pervasive appeal to the Trinity in understanding the divine-human relationship is delineated and imaginatively rendered. Tracing the trinitarian theme in its many dimensions throughout the reformer's work, Philip Butin offers a revised look at the vital role of the Trinity in Calvin's thought, in the process recovering Calvin as a significant historical source for contemporary trinitarian theological reflection.
