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 in three volumes and ultimately combined as Mere Christianity. In this book, 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. Written in the informal manner in which Lewis delivered his radio lectures, this collection eases students into the world of apologetics.
