Frederik A.V. Harms examines Calvin's ecclesiology based on his commentary on the Little Prophets from 1557–1559. Harms presents Calvin's view of the church from a historical-systematic perspective. His study of the great reformer's ecclesiology is accompanied by two historical parts. On the one hand, Harms Calvin offers historical context from 1558 to 1559, when he gave lectures on the Little Prophets. On the other hand, Harms provides an overview of the history of interpretation of the Little Prophets from the early church to the first generation of reformed orthodoxy.
