Lewis's discourse on Christian Behavior continues with this chapter on justice and society. His reflections and conclusions are fascinating and relevant: "...The real snag in all this drawing up of blueprints for a Christian society [is that] most of us are not really approaching the 

subject in order to find out what Christianity says: we are approaching it in the hope of finding support from Christianity for the views of our own party. We are looking for an ally where we are offered either a Master or—a Judge."
