This volume presents the spirituality of John Calvin in three short texts drawn from his Institutes of the Christian Religion. Many consider Calvin the most influential thinker of the sixteenth century. His ideas flowed from Geneva into northern Europe, to the English-speaking lands of Britain, and through the Puritans to North America. The prolific writings of Calvin across several genres open up many aspects of Christian living, and each one offers an entree to his spirituality. On the supposition that "spirituality" refers to the way people or groups lead their lives in relation to ultimacy, three texts have been chosen to form the axis for this interpretation of Calvin's contribution. These texts deal with his theological view of law, a definition of sanctification, and a short treatise on the Christian life. The portrait of Calvin's spirituality that emerges from these texts and the larger framework of his theology, his ecclesiology, and his career as church leader and civic organizer can be summarized in the following phrase: a practical spirituality of sanctification by participation in society. One cannot find all of that in these texts, but they establish a platform on which the pieces fall into place. The story of his early life and formation, along with several key ideas that characterize the man and his vision, will help to draw a sharper, more distinctive picture of at least this influential aspect of Calvin's spirituality. It is one that bears direct relevance, with appropriate adjustments, to life today.
