Delve into the arguments central to Christianity as C.S. Lewis in Mere Christianity creates a rational case for his religion. Although slightly preachy in its format, this resource fully outlines, in two different sets, the essential questions, philosophies, and ideas presented by Lewis in his radio addresses. Many questions are complex enough to develop into essays, but are also well-suited to incite debate. The instructor can choose the questions between the sets that are best suited for the needs of the class.
