"Christianity, if false, is of no importance, and if true, of infinite importance. The only thing it cannot be is moderately important"
About this Quote
The craft is in the calibration of scale. Lewis pairs “no importance” with “infinite importance,” extremes that refuse the modern habit of treating beliefs as lifestyle accessories. The subtext is practical: if the resurrection and the claims about God are true, then Christian ethics aren’t optional advice and worship isn’t private therapy; they’re responses demanded by reality. If they’re false, then Christianity isn’t a “good framework” that deserves partial subscription. It’s error dressed as meaning, and error doesn’t become noble by being comforting.
Context matters: Lewis writes as a former atheist turned Christian apologist, speaking into a 20th-century Britain where Christianity lingered as cultural wallpaper even as conviction thinned. Postwar anxiety and disillusionment made “soft” belief tempting: keep the ceremonies, keep the moral language, keep the social cohesion. Lewis treats that compromise as intellectually dishonest. The quote works because it doesn’t argue Christianity is true; it argues that half-belief is a category mistake. It forces the reader to feel the cost of evasiveness.
