Which Christian denomination did C.S. Lewis join after his 1931 conversion?

After his 1931 conversion, C.S. Lewis joined the Church of England.

Lewis had been raised in the Church of Ireland, but his religious views changed substantially during adulthood. He moved from atheism toward Christianity through a long intellectual and personal process, influenced by conversations with friends including J.R.R. Tolkien and Hugo Dyson.

Lewis described his return to Christianity as occurring in 1931. He became an Anglican, the tradition represented in England by the Church of England, and remained associated with it for the rest of his life. His apologetic writings often addressed broad Christian audiences rather than defending only one denomination.

A common mix-up is to identify Lewis as Roman Catholic because of his close friendship with Tolkien, who was Catholic. Tolkien influenced Lewis’s thinking about myth and Christianity, but Lewis himself was Anglican. Lewis’s denominational identity is therefore distinct from Tolkien’s.
