John Calvin was ever the pastor, not only to those close to him but also to those far away, not only to normal believers but also to those in high places. In the dedicatory letters to his writings, Calvin very often addresses kings, queens, and other rulers. He places their reigns on the continuum of the kingdom of Christ from its beginning until its consummation. On this continuum, Calvin encourages and exhorts rulers to work for the restoration of true doctrine and the eradication of all heresy. He does this in the context of each dedicatee’s context and current affairs. These texts reveal a form of pastoral ministry seldom discussed.
