The Obamas and Clintons visited the tomb of John F. Kennedy at Arlington National Cemetery. November 22 was the 50th anniversary of Kennedy’s assassination. That tragedy completely overshadowed the death on the same day of Clive Staples Lewis—C.S. Lewis, widely considered one of the world’s most influential writers about the Christian faith. He taught English literature at Oxford and also wrote Mere Christianity, The Screwtape Letters, The Chronicles of Narnia, and other books that still sell up to two million copies a year. Lewis was an atheist who became a Christian. He called himself “the most reluctant convert in all England.” He was 64 years old.
