Luther saying that the gospel enables the Christian to say to Satan “kiss my backside”
“It is the supreme art of the devil that he can make the law out of the gospel. If I can hold on to the distinction between law and gospel, I can say to him any and every time that he should kiss my backside. Even if I sinned I would say, ‘Should I deny the gospel on this account?’
. . .once I debate about what I have done and left undone, I am finished. But if I reply on the basis of the gospel, ‘The forgiveness of sins covers it all,’ I have won.”
–Martin Luther, quoted in Reinhard Slenczka, “Luther’s Care of Souls for Our Times,” Concordia Theological Quarterly 67 (2003): 42.
