Within the realm of Christian theology there are many fiercely debated topics. One such topic is the question of the how the Law is to be understood in the Christian faith, especially in the light of the gospel and in the life of the Christian.
Taking on this task, Reformation thinkers Martin Luther and John Calvin both put forth ideas of how the Law is to be understood within Christianity.
When given a cursory reading, it will be noticed that Luther put forth two different uses of the Law, whereas Calvin put forth three, a distinction which has caused a fair amount of dispute between Lutheran and Reformed theologians to this day.
In order to gain a better understanding of this doctrine is helpful to compare and contrast these two great thinkers’ views on the topic, paying careful attention to how and why they draw the distinctions that they do. For John Calvin, it will be necessary to analyze his Institutes of the Christian Religion, where he lays out what he sees to be the three uses of the Law. For Martin Luther, it will be necessary to first look at his Commentary on Galatians, where he lays out what he sees to be the two primary uses of the Law; with this done, it will also be necessary to look at various other of Luther’s writings to discern whether or not he indeed limits the use of the Law to those two areas.
Because Calvin is more systematic in his approach to the topic of the uses of the Law, it will be helpful to discuss him first, and thereby gain a solid understanding of the field to be analyzed; with this done we can consider how Luther compares in his writings, both explicitly and implicitly.
