A hundred and fifty years ago today, as the sun broke through the clouds shortly after noon on a wet Washington day, Abraham Lincoln, with one hand raised and the other on an open Bible, took the presidential oath of office for the second time. The speech he just gave had been received by an enthusiastic crowd on the East Portico of the U.S. Capitol. It took about six minutes. Then the oath. Then he said, “So help me God,” bent forward, and kissed the Bible to conclude the solemn ceremony.
