What was the original title of C.S. Lewis’s first BBC broadcast series on Christianity?

The original title of C.S. Lewis’s first BBC broadcast series on Christianity was Broadcast Talks. The talks were delivered during the Second World War and later revised and published in book form.

Lewis began broadcasting the talks in 1941, when the BBC sought clear religious programming for a public living through wartime uncertainty. His conversational style made difficult theological ideas accessible to a broad audience.

The material was later published in Britain under titles including Broadcast Talks, Christian Behaviour, and Beyond Personality. These sections were eventually brought together as Mere Christianity, the title most readers now recognize.

Because Mere Christianity is the famous collected book, it is often incorrectly treated as the original broadcast title. The broadcasts were also not church sermons in the usual sense; they were carefully prepared radio talks intended for listeners from different Christian backgrounds and for people exploring Christianity.
