C.S. Lewis’s The Screwtape Letters offers many interesting and sometimes controversial theological views on a diverse number of topics. While most all of the topics are of at least some interest, certain topics are of particularly greater interest, prompting the reader to question Lewis’s theories and consider the views offered by the world, the bible, and in some cases, science. When the inquiring mind probes these different fields, they will find that they differ almost religiously, often to the point of being complete opposites. However, the Christian reader finds truth only in one of these sources, that being the bible, the very word of God. Therefore to find whether author C.S. Lewis’s theological views are sound and to be trusted, or to scoff at, Christian readers will turn to the word of God for answers. After doing so, the reader will find that C.S. Lewis gives great insight and clarity on the theological issues of purity, love, and marriage. C.S. Lewis talks about these three closely related topics in The Screwtape Letters mainly over the span of three letters. In a way he works in a backwards fashion through these topics, starting first with marriage, then leading on to love, and ending the three linked topics with purity. The human life from teenager to adult often follows a pattern of first struggling with sexual purity, eventually falling in love, and then possibly resulting in marriage; thus this is the route this essay will follow. Unfortunately, the proof for Lewis’s soundness in his statements lies scattered across many different verses, chapters, and books of the bible. Luckily for the reader, however, these proofs have been compiled in this (hopefully) clear cut essay.…
