Flannery O’Connor was thrice blessed: she was Catholic, she was southern and she was an Irish American. She also was one of the great writers of the 20th century combining an extraordinary ability to put words together in a pleasing way with a talent for developing stories and mesmerizing readers. Many of her writings are deeply Catholic. And she was a top drawer Thomist. The inestimable Ralph Wood, a scholar of the first order affiliated with Baylor University has written a thorough and fascinating piece dealing with “the place of the demonic” in O’Connor’s writings.
