Question: “Doctor, many men think and say that the law should be emphasized often for the sake of the profane common people, lest they abuse the gospel. Others say that the common man ought not to be cited as a reason but only the command of Christ, who wishes that the goodness of the Father may become known through the gospel. Which of these opinions is the better?”
The doctor [Martin Luther] replied, “This shouldn’t and can’t be comprehended in a fixed rule. Christ himself preached [the law and the gospel] according to his circumstances. As a passage or text indicates, therefore, one should take up the law and the gospel, for one must have both. It isn’t right to draw everything into the gospel alone; nor is it good always to preach the law alone. The Scriptures themselves, if properly adhered to, will give the answer.”
