John Calvin has been the subject of numerous studies, but most have focused on one aspect of his thought or a limited selection of his writings. This study of Calvin adopts a uniquely holistic approach. Randall Zachman begins with a brief biography and considers Calvin's own understanding of his ministry as a teacher and pastor. From this perspective, he surveys Calvin's writings and their place in the work of reforming the church - both through the training of clergy and the instruction of the laity. Zachman then considers Calvin as a theologian. In contrast to Martin Luther, Calvin sought to balance the verbal proclamation of the Word with an emphasis on the visible manifestation of God - both in creation and in Christ. This study will be of great interest to Reformed clergy and to students of the Reformation and Calvinism.
