"In 1943 England, when all hope was threatened by the inhumanity of war, C. S. Lewis was invited to give a series of radio lectures addressing the central issues of Christianity. First heard as informal radio broadcasts, the lectures were then published as three books and subsequently combined as Mere Christianity. C. S. Lewis proves that "at the center of each there is something, or a Someone, who against all divergences of belief, all differences of temperament, all memories of mutual persecution, speaks with the same voice," rejecting the boundaries that divide Christianity's many denominations."--BOOK JACKET.
