C.S. Lewis set of 3 Books: Christian Behaviour, Beyond Personality, Broadcast Talks

Beyond Personality, Christian Behaviour, and Broadcast Talks are the three separate books by C.S. Lewis that were combined to form his classic work of Christian apologetics, Mere Christianity. 

These books were comprised of immensely popular radio talks, with a broad British audience during wartime and were first published individually as booklets. In 1952, C.S. Lewis gathered the three works, revised them, and published them together under a new title, Mere Christianity.

This set includes each of the three books, published 1951-52.
