C.S. Lewis described his conversion to Christianity as taking place in 1931. He had returned to belief in God earlier, but he later identified 1931 as the year he accepted Christianity.
Lewis’s intellectual and spiritual journey included conversations with fellow writers J.R.R. Tolkien and Hugo Dyson. On 19 September 1931, Lewis, Tolkien, and Dyson discussed Christianity and myth during a late-night conversation at Oxford. Lewis’s conversion followed this period of reflection, though accounts simplify a process that unfolded over several years.
His later Christian writing included Mere Christianity, The Problem of Pain, and The Screwtape Letters. Lewis was an Anglican, and his works generally aimed to explain shared Christian beliefs rather than promote a narrow denominational position.
