Why C.S. Lewis Is Essential

C.S. Lewis's contribution to Christianity is extraordinary. Mere Christianity has brought more people to faith than almost any other book of the 20th century. The Chronicles of Narnia has shaped the moral and spiritual imagination of generations of children. The Screwtape Letters provides unparalleled insight into spiritual warfare. The Problem of Pain and A Grief Observed engage suffering with unusual theological and emotional depth.

Lewis was a brilliant Oxford scholar who became a Christian through intellectual argument — his conversion provides one of the most compelling examples of faith reached through serious thought rather than despite it. His writing is clear, honest, and deeply Christian in its fundamental orientation.

Theological Nuances to Know

Some evangelicals have concerns about Lewis that are worth knowing honestly. He held views on purgatory that are closer to Catholic than Protestant theology. He expressed what some call "broader hope" — the possibility that those who never heard the gospel might be saved through responding to the light they had. He smoked a pipe, drank beer, and didn't treat these as sins. These are theological positions that serious Reformed and evangelical Christians disagree with. They do not disqualify Lewis as a Christian or as an essential Christian thinker — they are the nuances of engaging any writer across theological traditions. See C.S. Lewis overview.
