The spark that still shines: John Calvin on conscience and natural law

John Calvin (1509–64), a central figure in Reformed theology, is perhaps best known for his bleak doctrine of total human depravity. This dismal view of human reason has commonly overshadowed his statement that ‘some sparks still shine’. This article proposes that Calvin’s account of conscience, by conserving an illuminated space in human nature, makes possible a formal doctrine of natural law. Calvin enlists the interconnectedness between the knowledge of God and human reason to frame his anthropology. According to this, human reason was originally created to perfectly access knowledge of God but after the Fall, can only attain imperfect access. Within this broader framework, by adopting a dialectic of dual perspectives, Calvin maintains that, however fallen, human nature still partially reflects the Imago Dei as first intended. As through a glass darkly, this divine image is reflected in human conscience endowing it with sufficient knowledge for moral discernment. Calvin’s emphasis on ‘common grace’ in the preservation of this knowledge allows him to simultaneously maintain human ignorance and their universal accountability to objective norms. In this way, Calvin’s account of conscience enables him to hold both apparent extremes in tension: the immanent fallibility of human beings with the external normative standards they ought to pursue.
