What Christian denomination did C.S. Lewis belong to when he died?

C.S. Lewis belonged to the Church of England when he died.

Lewis was raised in the Church of Ireland, which is part of the Anglican Communion. Although he became an atheist during his youth, he returned to Christianity in the late 1920s and became an Anglican.

His conversion developed through conversations and friendships, especially with Christian writers such as J.R.R. Tolkien and Owen Barfield. Lewis later wrote widely read works explaining Christian belief, including Mere Christianity and The Problem of Pain.

Lewis was not a Roman Catholic, although his writings influenced readers in many Christian traditions. He also did not present himself as the founder of a separate denomination. At his death in 1963, he was a communicant member of the Church of England.
