Which Christian denomination did C.S. Lewis join in 1931?

C.S. Lewis joined the Church of England in 1931.

Lewis was raised in the Church of Ireland, but his religious commitment changed significantly during adulthood. After a period as an atheist, he returned to Christianity in stages, influenced by philosophical reflection, reading, and conversations with friends including J.R.R. Tolkien and Hugo Dyson.

In 1931, Lewis became a member of the Church of England. He remained an Anglican for the rest of his life and became one of the twentieth century’s most widely read Christian writers. His works include Mere Christianity, The Problem of Pain, and The Screwtape Letters.

Lewis’s writings often sought common ground among Christians rather than focusing on denominational disputes. “Mere Christianity” was his term for the shared core of belief found across major Christian traditions, not the official name of a denomination.
