As a Lutheran, I would take exception that Calvin is more important than Luther. It was Martin Luther, long before John Calvin, that had established the Protestant work ethic and the teaching on vocation. I would agree with his views on the difference between Calvin and Luther when it comes to the distinction between the two kingdoms. As the saying goes, Calvin loved the glory of God, while Luther gloried in the love of God.

Luther and Calvin served their purpose.
