"But she was a heretic," I remarked. I can never forget her smile. The sun had arisen in her eyes. "We live in the twentieth century," she replied. And, unconsciously, we both heaved a sigh of relief. I rubbed my eyes to be sure we were not living in the middle ages, when Rationalism was still a babe in swaddling clothes, and Theology was lord of all. This is the twentieth century--for we are drinking at the fountain of Joan of Arc instead of carrying fagots to her stake! One of the sunniest spots in my memory will be my meeting with this peasant woman, with her pitcher, at the fountain of Joan of Arc. But my object in this lecture is to help clear some obscure questions in connection with the trial, martyrdom and subsequent canonization of this girl of nineteen. I wish to bring about a more intelligent appreciation of the story of a young shepherdess, beginning from the day she left her home in Domremy, to the fiery scaffold; and thence to a place among the saints in the Catholic calendar. This is the only instance in Catholic history of a person once destroyed as a heretic who has afterwards received the highest honors within the gift of the Church. In fourteen hundred thirty-one an infallible body of ecclesiastics pronounced this young woman to be "a child of perdition, a sorceress, a seducer, a harlot and a heretic." Five hundred years after, another infallible body of ecclesiastics belonging to the same church pronounced the same "harlot" and "heretic" to be "angelic" and "divine." One infallible pope allowed her to be burned in fourteen hundred thirty-one; another infallible pope denounced her murderers as detestable criminals--which shows how fallible is infallibility.
