What name was given to C.S. Lewis’s BBC radio talks later published as Mere Christianity?

C.S. Lewis’s BBC radio talks were first published under the name Broadcast Talks.

Lewis delivered a series of Christian radio talks for the BBC during the Second World War. The first group was broadcast in 1941, followed by additional series in 1942 and 1944. The talks were written for a general audience and explained basic Christian ideas without depending on a particular denomination.

The initial book version appeared in 1942 as Broadcast Talks. Later collections brought the material together under the titles Christian Behaviour and Beyond Personality. In 1952, the three sections were revised and published together as Mere Christianity, the title now most familiar to readers.

Because Mere Christianity is the standard modern title, readers may overlook the earlier publication name. Broadcast Talks is not a separate argument unrelated to the later book; it is the original title of the first collected portion of Lewis’s BBC work.
