Mere Christianity by C.S. Lewis
Widely considered one of the greatest works of Christian apologetics ever written, Mere Christianity by C.S. Lewis began life not as a book, but as a series of radio lectures given by Lewis over the BBC to World War II ravaged Britain. Later expanded into book form, Mere Chirstianity explores the most basic (or “mere”) beliefs common to all branches of orthodox Christianity. Employing his razor sharp intellect, Lewis presents a logical case for each of these beliefs, and a compelling argument for Chirstian belief as a whole.
Mere Christianity is not a lite read, but for anyone interested in religion or historical Christianity, it is a very rewarding one.
