Calvin's great concern is that Christians should "rightly use the Lord's Supper." He is, from beginning to end, a pastoral theologian (surely any other kind is guilty of a category mistake?).
In seeking to serve the church he wants to be sensitive to two things: (i) the mystery of the Lord's Supper, and (ii) the nature of communion with Christ..
Calvin now turns to the theme of the Lord's Supper. His concern is twofold: (i) to provide a simple explanation of the Supper and (ii) to resolve difficulties related to it. What he does in IV. 17. i is worthy of imitation, namely the provision of a simple but rich exposition of the meaning of Communion. This at least we should share with Calvin: a concern that the Lord's people understand what they are doing at, and how they are to think about, the Supper: What is the Lord showing us at the Table?
"Fear not, Abram: I am thy shield, and thy exceeding great reward."
In my last letter, I wrote that the Puritans show us how to marry doctrine and practice in our preaching. I'd like to add that they stressed the practice of piety (praxis pietatis), or practical godliness, flowing out of sound doctrine—just as much as Augustine and Calvin before them.
The Westminster Directory for Worship summarizes the Puritans’ commitment to sanctified application:
Olaudah Equiano – Waking Up Christians to the Evils of Slavery
John Chrysostom and Olympias – Finding Comfort in Troubled Times
Basic information – four ideas
