Which religion did C.S. Lewis embrace in 1931 after returning to belief?

The story behind the answer

C.S. Lewis embraced Christianity in 1931 after returning to religious belief.

Lewis had described himself as an atheist for part of his adult life, although his views developed through reading, conversation, and philosophical reflection. His friendship with J.R.R. Tolkien and Hugo Dyson was especially influential during the period in which he reconsidered Christianity.

Lewis became a theist in 1930 and then returned to Christianity in 1931. He later became one of the twentieth century’s most widely read Christian writers, producing works such as The Problem of Pain, Mere Christianity, and The Four Loves.

The date is sometimes simplified to “1930,” because that was the year Lewis moved from atheism toward belief in God. The more specific milestone usually given for his conversion to Christianity is 1931. His writings drew on Anglican Christianity, although his influence extended across many Christian traditions.
