C.S. Lewis embraced Christianity in 1931 after a long process of conversion.
Lewis had returned to belief in God in 1929, but he later described his commitment to Christianity as taking shape in 1931. Conversations with fellow writers J.R.R. Tolkien and Hugo Dyson helped him reconsider how Christian belief related to myth, history, and the person of Jesus. Lewis’s conversion became a major turning point in his intellectual and literary life.
The dates 1929 and 1931 are both connected with his religious development, which can cause confusion. In 1929, Lewis became a theist; by 1931, he identified as a Christian. He later became one of the twentieth century’s best-known Christian apologists through books, broadcasts, essays, and lectures.
