Here is a brief excerpt and introduction:
C. S. Lewis was an Anglican, not a Lutheran, yet he had a remarkable grasp of the role of Law and Gospel. Even when Lewis championed the notion of mere Christianity, as the vestibule from which one could choose between various denominations 5, his presentation of the basic claims of Christianity presupposes the distinction. The idea is further illustrated throughout his works.
This paper will begin by substantiating Lewis’s commitment to the Law/Gospel distinction in his basic theology. It will then examine two of the methods Lewis used to present the Law as an effective preparation for the Gospel. These techniques are of interest both for sermon writing and for pre-evangelistic witness and apologetics.
