Mere Christianity is a wonderful distillation of the beliefs that unite Christianity across its many denominations, delivered by one of the twentieth century’s most talented and compelling writers. As a former atheist himself, Lewis is well-positioned to deliver compelling arguments and counter-arguments for Christianity, steel-manning his arguments against outside criticisms and objections. In this masterclass of Christian apologetics Lewis delivers excellent arguments and explanations for the existence of a transcendent moral law; explains the nature and reason for evil and pain; advocates the importance of the virtues of prudence, temperance, justice, and fortitude; the importance of persistent faith and sacrifice despite failure; and gives the most digestible explanation of trinitarian monotheism I have encountered.
Mere Christianity is a short read, yet it is worth absorbing it slowly and reflecting on the arguments Lewis is presenting in each chapter. This book was originally a series of radio addresses, and even in its written form, it reads like a conversation. Each chapter is a perfectly succinct argument or musing on a particular aspect of Christian belief, and this makes this Mere Christianity an easy document to quickly reference and re-read.
